APC Symmetra PX - UPS ( External ) - AC 208 V - 30 KW - UPS Battery Lead Acid - - SY30K40F

APC by Schneider Electric SY30K40F Symmetra PX 30kW Modular UPS

Overview

The APC SY30K40F is a 30 kW / 30 kVA three-phase modular uninterruptible power supply designed for data center rows, critical server rooms, and infrastructure deployments where a power interruption — even a brief one — carries serious operational or financial consequences. Running on 208V AC input at 60 Hz, it fits natively into standard North American data center electrical infrastructure without requiring a transformer. The Symmetra PX platform is APC's scalable, frame-based architecture: this 30 kW configuration delivers full rated output from day one while leaving headroom in the Symmetra PX chassis for capacity expansion as your load grows.

For enterprise UPS and power protection deployments, the SY30K40F occupies a well-defined middle tier — large enough to carry a full rack row or a mid-scale virtualization cluster, compact enough to avoid the infrastructure commitments of larger three-phase systems. If you're specifying power protection for a high-density switching or compute environment, the 30 kVA output capacity and 30,000 W real power rating give you substantial margin over typical 80% loading recommendations.

Key Features

• 30 kW / 30 kVA Output Capacity: Full 30,000 W of real power output means no derating games — what's on the nameplate is what the system delivers to your load. At the 80% utilization ceiling most data center managers target, that's 24 kW of usable protected capacity, enough to cover a dense compute row or a mid-scale UPS zone without parallel units.
• Lithium-Ion Battery Technology: Li-Ion chemistry runs cooler and tolerates more charge/discharge cycles than traditional VRLA designs before capacity degrades. In a data center environment where the UPS may float on charge for years between actual events, the reduced sensitivity to partial-state-of-charge cycling is a meaningful longevity advantage. Replacement battery cartridge is the SYBT4.
• 3.7 Minutes at Full Load / 14.2 Minutes at Half Load: These are short runtimes by design — the Symmetra PX is engineered as a bridge-to-generator architecture, not a standalone long-runtime system. If your site has a generator with a 60–90 second start-and-transfer time, 3.7 minutes at full load is sufficient margin. If you need 15+ minutes at full load without a generator, this unit is undersized for that scenario and you should consider external battery modules or a different UPS topology.
• 2-Hour Battery Recharge Time: After a discharge event, the system returns to full battery capacity in approximately 2 hours — fast enough that a second power event later in the same shift won't find the battery still depleted from the first.
• Emergency Power Off (EPO): EPO capability is a code requirement in most data center build-outs (NEC Article 645) and a practical necessity in any room where electrical personnel need to de-energize UPS output fast. The SY30K40F supports EPO, so it integrates cleanly with facility EPO switch panels without requiring external bypass engineering.
• Integrated Ethernet LAN (RJ-45) Port: The onboard network interface enables UPS monitoring, alerting, and graceful shutdown signaling over your existing network infrastructure — no separate network management card required for basic connectivity. This matters when you're integrating with a DCIM platform or configuring automated shutdown sequences on protected servers.
• 64 dB Noise Level: At 64 dB, this unit is louder than a typical office environment (around 50–55 dB) but consistent with data center floor noise. It is not appropriate for open office or near-workspace installations. In a dedicated server room or data center, this won't be a factor.
• Operating Temperature Range 0–40°C: Standard data center operating envelope. Storage temperature down to -15°C means the unit can ship and stage in unheated facilities during winter without damage, as long as it's allowed to acclimate before energizing.
• 0–95% Operating Relative Humidity: Wide humidity tolerance reduces the risk of nuisance shutdowns in environments where HVAC control is imperfect, such as edge deployments or older facilities without precision cooling.
• Audible Alarm: Built-in audible alarm gives on-site personnel immediate notification of a power event without requiring them to be watching a monitoring console — relevant in unmanned or lightly staffed data closets.

Integration and Compatibility

The SY30K40F connects to network management and DCIM systems via its integrated RJ-45 Ethernet port. The APC by Schneider Electric Symmetra PX platform is broadly supported by EcoStruxure IT and APC's PowerChute software suite for automated graceful shutdown of protected servers. For facilities running VMware, Microsoft Hyper-V, or other hypervisor environments, PowerChute integrates with the hypervisor layer to execute live migrations and ordered shutdowns before battery reserves are exhausted.

The 208V AC input aligns with standard data center PDU infrastructure in North America. Verify that your upstream distribution panel and circuit breakers are sized for the inrush and steady-state draw of a 30 kW UPS before installation — consult the APC installation guide for specific breaker sizing requirements. The EPO input requires connection to your facility's EPO switch network; confirm termination and polarity with your electrical contractor before commissioning.

The replacement battery cartridge for this unit is the SYBT4. Hot-swap battery replacement is not supported on this model — plan battery maintenance windows around scheduled downtime. For facilities where zero-downtime battery service is a hard requirement, evaluate whether a parallel-redundant UPS configuration or a model with hot-swap capability better fits the operational need. For complete APC UPS sizing and selection, consider the full Symmetra PX family range to match your growth trajectory.

If your deployment requires extended runtime beyond the 14.2-minute half-load figure, external battery enclosures compatible with the Symmetra PX platform can extend runtime substantially — confirm compatibility with the specific frame configuration before ordering. For power protection planning in multi-rack deployments, factor in the 30 kW ceiling when aggregating per-rack load estimates.

Frequently Asked Questions

Q: What is the runtime of the SY30K40F at full load?

A: At full 30 kW load, the SY30K40F provides approximately 3.7 minutes of battery backup. At half load (15 kW), runtime extends to approximately 14.2 minutes. This unit is designed as a bridge-to-generator system — if your site does not have a generator, evaluate whether extended runtime battery modules are appropriate for your application.

Q: What battery cartridge does the SY30K40F use?

A: The SY30K40F uses the SYBT4 replacement battery cartridge. Note that hot-swap battery replacement is not supported on this model, so battery maintenance requires planned downtime.

Q: Does the SY30K40F support Emergency Power Off (EPO)?

A: Yes. The SY30K40F includes EPO capability, allowing integration with facility EPO switch panels to de-energize UPS output in emergency situations. This satisfies NEC Article 645 EPO requirements common in data center build-outs.

Q: What input voltage and frequency does the SY30K40F require?

A: The SY30K40F operates on 208V AC input at 60 Hz, which is standard for North American data center electrical distribution. Confirm your upstream circuit breaker sizing with the APC installation documentation before commissioning.

Q: Does the SY30K40F include network monitoring capability?

A: Yes. The unit includes an integrated Ethernet LAN (RJ-45) port for network-based UPS monitoring, alerting, and graceful shutdown integration. This enables connection to DCIM platforms and compatibility with APC PowerChute software for automated hypervisor shutdown sequences.

Q: What is the operating temperature range for the SY30K40F?

A: The SY30K40F operates between 0°C and 40°C (32°F to 104°F) with 0–95% relative humidity. Storage temperature range is -15°C to 40°C, allowing staging in unheated facilities as long as the unit acclimated before energizing.

The SY30K40F sits in a specific and well-defined role in data center power architecture — 30 kW of protected output on a Symmetra PX frame, 208V input, Li-Ion battery chemistry, and a 3.7-minute full-load runtime that tells you exactly what this unit is built for: bridging the gap between a utility interruption and a generator that's already on-site and ready to transfer. If you're evaluating this unit, start with that runtime figure and work backward from your generator transfer time before anything else.

Technical Highlights:

• 30 kW / 30 kVA Output: Full rated real and apparent power with no derating — at 80% target utilization that's 24 kW of protected load, enough for a dense 10–12 rack row or a mid-scale hyperconverged cluster.
• Li-Ion Battery, SYBT4 Cartridge: Li-Ion handles years of float charging without the sulfation issues that degrade VRLA batteries in low-event environments. The SYBT4 is the service path — source it before you need it, not after a battery health alert fires at 2 AM.
• Integrated RJ-45 Network Port: Onboard Ethernet means you can connect this to your management VLAN and configure PowerChute graceful shutdown sequences on day one without ordering a separate network card — a common oversight on large UPS purchases that delays commissioning.

Deployment Considerations:

• Hot-swap battery replacement is not supported. Schedule battery maintenance windows during planned downtime cycles — this is a non-negotiable constraint if your SLA requires continuous uptime during service events.
• The 3.7-minute full-load runtime is intentionally short. Deploying this unit without a site generator or external battery extension strategy leaves your load exposed in any extended utility outage. Confirm generator ATS transfer time before signing off on this specification.

The SY30K40F is the right specification for a mid-scale data center row or colocation cage where a generator is already part of the power design, the electrical infrastructure is 208V, and the priority is clean power conditioning and fast bridge-time rather than extended standalone runtime. Edge deployments without generator backup or environments needing 15+ minutes of full-load runtime should look at external battery frame options within the Symmetra PX family before committing to this configuration.
