APC by Schneider Electric SYA8K8P Symmetra LX 8kVA Online UPS Power Array

The APC by Schneider Electric SYA8K8P is an 8000VA / 6400W double-conversion online UPS designed for mission-critical infrastructure where a momentary power interruption is unacceptable. Built on the modular Symmetra LX platform, this external power array runs true online double-conversion at 96% efficiency — delivering clean, conditioned sine-wave output continuously, not just during a transfer event. If you're protecting a security operations center, network equipment room, or edge compute cluster drawing up to 6.4kW, the SYA8K8P belongs on the short list.

Overview

The Symmetra LX architecture separates power capacity from battery runtime, which matters when you're sizing a UPS for a real deployment rather than a worst-case spec sheet exercise. The SYA8K8P ships with two power modules installed and one free slot remaining — meaning you can add a third power module later to increase capacity without replacing the frame. Two battery modules are included and all battery slots are filled at the factory, giving you runtime out of the box with a 3-hour typical recharge time after a full discharge event. The unit is floor-standing (not rack-mountable), finished in black and silver, and weighs just under 445 lbs — factor this into your floor load calculations before specifying it for a raised-floor environment.

Key Features

• Double-Conversion Online Topology: The SYA8K8P runs load power through the inverter 100% of the time, not just during a transfer. There is no transfer time on a power event — the load never sees the mains directly. This matters for sensitive electronics that fail or corrupt data on even a 4ms switchover. If your NVR or server storage has strict input requirements, this is the topology you want, not line-interactive.
• 8000VA / 6400W at 0.8 Power Factor: Rated at 8kVA with a real-power ceiling of 6.4kW, the SYA8K8P handles a substantial equipment load. Verify your actual connected load in watts — not VA — before finalizing the selection. Maximum configurable power is confirmed at 6400W / 8000VA, and maximum output current is 37A.
• 96% Efficiency at Full Load: Double-conversion UPS systems traditionally sacrifice efficiency for protection. At 96% full-load efficiency, the SYA8K8P keeps heat dissipation to 3,485 Btu/h — still significant in a sealed room, but more manageable than older ferro-resonant or low-efficiency designs. Plan your cooling accordingly.
• Modular Power Expansion — 1 Free Slot Remaining: With two power modules installed and one slot open, you can grow capacity in 4kVA increments (per the Symmetra LX product sub-family designation) without swapping the frame. This is a meaningful operational benefit: you don't need to schedule a replacement outage just because your load grew.
• Hard-Wire 4-Wire Output (2PH+N+G): Output is hard-wired, not receptacle-based. This is the correct configuration for permanently installed critical infrastructure loads but requires a licensed electrician for installation and commissioning. If you need receptacle outputs for a server rack PDU, confirm your downstream distribution is compatible before ordering.
• Configurable 208V or 240V Nominal Output: The SYA8K8P supports both 208V and 240V nominal output configurations — useful in environments where the downstream load mix or utility feed varies. Input accepts 120V/208V/240V AC at 45–65 Hz with auto-sensing frequency, covering both 50Hz and 60Hz infrastructure without manual reconfiguration.
• Input Power Factor 0.98 / THD Below 7%: A 0.98 input power factor means the SYA8K8P draws very close to pure real power from your utility feed — minimizing reactive loading on your electrical infrastructure. Input THD under 7% at full load keeps harmonic injection onto the building distribution well within the limits most facility engineers require.
• Lead-Acid Batteries — 3-5 Year Service Life: Battery modules use sealed lead-acid chemistry with an expected service life of 3 to 5 years. Replacement battery part numbers are SYA8K16PX798 and SYBT5. Budget for a battery replacement cycle at the 4-year mark in your maintenance plan. The typical recharge time after a full discharge is 3 hours.
• Sine Wave Output / Up to 5:1 Crest Factor: Pure sine wave output with a crest factor up to 5:1 means the SYA8K8P can handle loads with high peak-to-RMS current ratios — including switching power supplies, variable frequency drives, and medical-grade equipment that would clip or fault on a stepped-approximation waveform.
• Internal Bypass — Automatic and Manual: Built-in automatic and manual bypass allows the load to transfer to mains power for maintenance or fault isolation without a full shutdown. An optional external bypass is also supported for environments where zero-downtime maintenance is a hard requirement.
• Multi-Function LCD Control Panel: The front-panel LCD provides system status, alarms, and configuration access locally. Audible and visible alarms are prioritized by severity — you'll know if a critical fault is in progress versus a warning condition without digging into a management interface.
• Operating Environment — 0 to 10,000 ft Altitude: Rated for operation up to 10,000 feet altitude with 0–95% non-condensing humidity, covering most domestic data center and equipment room environments. Storage altitude extends to 15,000 ft. Acoustic output is 62 dBA — relevant if this unit is floor-mounted in an occupied or semi-occupied space.

Integration & Compatibility

The SYA8K8P is designed for integration into the broader APC by Schneider Electric Symmetra LX ecosystem. Runtime extension is supported via external battery frames — the extendable runtime flag is confirmed in specifications. For deployments requiring network-based monitoring, APC's SNMP management cards are compatible with the Symmetra LX platform (verify specific card compatibility with current APC documentation). The hard-wire output configuration requires coordination with a power distribution solution downstream — a rack-mount PDU accepting hard-wire input or individual branch circuit breakers. Review your UPS selection against actual measured load watts, not nameplate VA ratings, to avoid undersizing. For large security or IT deployments, pair this unit with a managed network switch on a separately protected circuit to maintain monitoring access even during a partial infrastructure event. Consult APC's runtime calculator with your specific battery configuration and load profile for accurate runtime estimates — published runtime tables vary significantly by load percentage.

Frequently Asked Questions

Q: What is the output voltage configuration of the SYA8K8P?

A: The SYA8K8P provides hard-wire 4-wire (2PH+N+G) output and is configurable for either 208V or 240V nominal output voltage. Main output voltage options are 120V, 208V, and 240V depending on configuration.

Q: Is the SYA8K8P rack-mountable?

A: No. The SYA8K8P is a floor-standing unit and is not rack-mountable. It is not compatible with two-post or four-post rack mounting. Plan for floor space and verify floor load capacity — the unit weighs approximately 445 lbs.

Q: How many battery modules are included, and what are the replacement part numbers?

A: Two battery modules are included and all battery slots are filled at the factory. Replacement battery part numbers are SYA8K16PX798 and SYBT5. Expected battery service life is 3 to 5 years with a typical recharge time of 3 hours after full discharge.

Q: Can the power capacity of the SYA8K8P be expanded?

A: Yes. The SYA8K8P ships with two power modules installed and one power module slot remaining. Capacity can be expanded in 4kVA increments by adding a compatible Symmetra LX power module to the open slot, up to the frame maximum.

Q: What is the UPS topology of the SYA8K8P and why does it matter?

A: The SYA8K8P uses double-conversion online topology. This means the load is powered through the inverter continuously — there is no transfer time during a power event. This is the appropriate choice for equipment that cannot tolerate even milliseconds of power interruption or voltage variation.

Q: What is the input power requirement for the SYA8K8P?

A: The SYA8K8P accepts input via a hard-wire 4-wire (2PH+N+G) connector at 208V or 240V AC, 45–65 Hz auto-sensing. Input power factor at full load is 0.98 and input total harmonic distortion is less than 7% at full load.
