APC Smart-ups RT 1000VA 230V Network Card - SURT1000XLI-NC

APC by Schneider Electric SURT1000XLI-NC Smart-UPS RT 1kVA Online Double-Conversion UPS

Overview

The APC by Schneider Electric SURT1000XLI-NC is a 1kVA / 700W rack/tower online double-conversion UPS designed for 230V environments where power integrity is non-negotiable. Unlike line-interactive or standby designs that react to outages, a double-conversion online topology continuously regenerates clean, regulated sine-wave output — meaning connected loads never ride raw utility power. Every joule passes through the inverter, so transients, sags, swells, and frequency deviations are absorbed before they reach your equipment. That architecture makes the SURT1000XLI-NC the right call for protecting network video recorders, edge servers, access control panels, and managed switches in deployments where a power event and a simultaneous security incident are the worst-case scenario.

The model ships with an integrated network management card slot, making remote power monitoring and load-shedding programmable from within your existing infrastructure management stack. For integrators building converged physical security and IT networks, that single detail changes the support model: you can respond to a power alarm without rolling a truck.

Key Features

• Double-Conversion (Online) Topology: Output is always inverter-derived — no transfer time on outage, zero voltage gap to connected loads. For NVRs mid-write or access control panels mid-door-cycle, even a 4ms transfer window in a line-interactive UPS is a risk. This topology eliminates it.
• 1 kVA / 700 W Capacity: Sized to protect a dense 1U rack shelf — typically a 16-channel NVR with two surveillance drives, a managed PoE switch, and a firewall simultaneously. Know your actual wattage draw before provisioning; 700W leaves margin for a typical mixed-security load but will be tight if you add a dense PoE injector.
• True Sine Wave Output: Active PFC power supplies in modern NVRs and servers require sine wave input or they run hot and fail early. The SURT1000XLI-NC delivers a clean sine waveform regardless of what arrives on utility input — relevant anywhere generator backup is part of the facility plan.
• Wide Input Voltage Range (100–280V AC): The 180V operating window means the UPS rides through brown-outs and overvoltage conditions that would force a lesser unit onto battery. On battery-constrained sites, that runtime preservation matters: you're not burning battery on a 15-minute voltage sag if the inverter can absorb it.
• 420 J Surge Energy Rating: Adequate for standard commercial surge events. Not a substitute for a dedicated surge suppressor upstream of sensitive broadcast or analog video equipment, but appropriate for protecting data-port-connected security appliances.
• 50/60 Hz Auto-Sensing Input Frequency: Deploys without manual jumper configuration in mixed-frequency facilities or international installations where the local grid frequency is indeterminate at procurement time.
• 89.1% Efficiency: For an online double-conversion design, 89.1% is typical class performance. At 700W continuous load, plan for roughly 79W of heat dissipation — factor that into rack thermal calculations in sealed IDF closets.
• Noise Level — 50 dB: Equivalent to a quiet office or library ambient level. Suitable for deployments in open office security operations centers or reception areas where fan noise from UPS hardware is a stakeholder concern.
• Audible Alarms — Low Battery + Overload: Onboard acoustic alerts for two of the most operationally critical conditions. In unattended equipment rooms, audible alarms provide a local early-warning layer independent of network notification systems.
• Auto-Restart: After a utility restoration following a deep discharge, the unit restarts automatically without a manual power cycle. Critical for remote or unmanned sites where a technician isn't available to restore equipment after an extended outage.
• 3:1 Crest Factor: Handles non-linear loads (switch-mode power supplies, UPS-to-UPS chained loads) without waveform clipping. Most commercial security hardware draws crest factors below 3:1, so the SURT1000XLI-NC will manage a realistic mixed load without output distortion.

Integration and Compatibility

The SURT1000XLI-NC (often searched as SURT1000XLI NC) includes a network card slot for remote management integration. The 230V / 50–60Hz specification targets European, Middle Eastern, Asian-Pacific, and international commercial installations — confirm your local grid standard before ordering. The UPS is compatible with APC's PowerChute software ecosystem for automated graceful shutdown sequencing on connected servers and NVRs. For power and UPS solutions in physical security infrastructure, the double-conversion topology pairs well with PoE switches and NVRs that run 24/7 without scheduled downtime windows. Integrators deploying network video recorders should size battery runtime against the longest expected power event or the NVR's graceful-shutdown time, whichever is shorter. Review APC's full APC by Schneider Electric catalog for extended battery module (XL) options that increase runtime on this platform. For multi-device deployments requiring centralized power management, pair with managed PoE switches that support SNMP-based power event coordination.

Frequently Asked Questions

Q: What is the difference between the SURT1000XLI-NC and a standard line-interactive UPS for NVR protection?

A: The SURT1000XLI-NC uses double-conversion (online) topology, meaning the inverter runs continuously and connected loads always receive inverter-generated power. A line-interactive UPS only activates its inverter on outage, creating a transfer gap of 4–8ms. For NVRs with active disk writes, access control panels, or servers with active PFC supplies, the zero-transfer-time of a double-conversion design is the operationally meaningful difference.

Q: What is the output wattage of the SURT1000XLI-NC, and how do I size my load?

A: The unit delivers 700W of real power (1 kVA apparent). Add up the nameplate wattage of every connected device. A 16-channel NVR (typically 30–60W), a managed PoE switch (varies widely by PoE budget utilization), and a firewall or router (15–40W) will typically land well within 700W, but measure actual draw with a clamp meter if you are close to the ceiling. Do not assume nameplate maximum equals typical operating draw.

Q: Does the SURT1000XLI-NC produce a true sine wave, and why does that matter for modern security hardware?

A: Yes — the SURT1000XLI-NC outputs a true sine wave via its inverter. Modern NVRs, servers, and managed switches with active PFC power supplies require sine wave input to operate correctly. Simulated (stepped approximation) sine wave can cause these supplies to run hot, generate audible buzz, or fail prematurely. Double-conversion designs inherently produce a clean sine waveform.

Q: What input voltage range does the SURT1000XLI-NC tolerate before switching to battery?

A: The unit accepts input from 100V to 280V AC before switching to battery. That 180V operating window provides substantial headroom against brown-outs and overvoltage events common in industrial or emerging-market grid environments, conserving battery runtime for true outage conditions.

Q: Does the SURT1000XLI-NC restart automatically after an extended outage?

A: Yes. Auto-restart is a confirmed feature — the unit will return to operation automatically after utility power is restored following a full discharge, without requiring a manual intervention at the equipment rack. This is essential for unmanned remote sites.

Q: What is the noise output of the SURT1000XLI-NC?

A: Rated at 50 dB, which is comparable to a quiet office environment. It is suitable for installations in occupied spaces such as security operations centers, reception desks, or small server closets adjacent to work areas.

The SURT1000XLI-NC sits in the part of the UPS catalog where topology choice matters more than any other spec. At 1kVA / 700W with a double-conversion online design, it delivers continuous inverter-sourced power — no wait, no transfer gap — which is the architecture I'd specify anywhere a power event coinciding with a security incident is an unacceptable scenario. The 100–280V input window is the other spec I keep coming back to: it's wide enough to ride through the brown-outs common in older commercial buildings without burning runtime on conditions the inverter can handle on its own.

Technical Highlights:

• Online Double-Conversion Topology: Loads never see raw utility power — the inverter is always in the signal path. Zero millisecond transfer time on outage is the practical result; NVRs mid-write and access control panels mid-transaction don't see a gap.
• 700W / 89.1% Efficiency: At full 700W load, expect roughly 79W of heat dissipation. In a sealed IDF closet with no active cooling, that is a real thermal contribution — account for it in rack planning alongside switch and NVR heat loads.
• 420J Surge Rating + Audible Alarms: The 420J rating covers standard commercial transient events. The dual alarms (low battery, overload) give local early warning independent of network connectivity — useful in equipment rooms where SNMP notification may itself depend on the powered network.

Deployment Considerations:

• The 230V / international spec means this unit is not the correct SKU for North American 120V installations — verify site voltage before procurement. The wide 100–280V input range applies to operating tolerance, not voltage selection.
• At 50 dB acoustic output, the SURT1000XLI-NC is manageable in occupied spaces, but double-conversion fans run continuously (unlike standby designs that only spin up on transfer) — factor that into deployments in quiet executive areas or recording studios sharing rack space with security hardware.

For a mid-size international commercial site running a 16-channel NVR, a managed PoE switch, and an access control server in a single rack, the SURT1000XLI-NC with its network card slot gives the security operations team both zero-gap power protection and remote power event visibility from a single appliance — exactly the right fit for a staffed SOC supporting a multi-building 230V campus.
