APC by Schneider Electric SUVTP20KF3B4S Online Double-Conversion UPS
Overview
The SUVTP20KF3B4S is a 16 kW (20 kVA) external, online double-conversion UPS from APC by Schneider Electric designed for three-phase AC input environments. Online double-conversion topology means the connected load runs entirely on conditioned power drawn through the inverter at all times — there is no transfer time to battery on a utility event, which matters when protecting sensitive servers, storage arrays, or network infrastructure where even a half-cycle interruption can trigger a fault.
With a 16 kW / 20 kVA power rating, the SUVTP20KF3B4S fits medium-density uninterruptible power supply applications: a loaded server rack, a network core room, or a security operations center where you need real power capacity behind a single unit rather than ganging smaller single-phase devices.
Key Features
- Online double-conversion topology: The load never touches raw utility power — voltage is rectified and re-inverted continuously, scrubbing sags, surges, and frequency variation before they reach your equipment. No transfer gap means no restart risk on servers or active recording systems.
- 16 kW / 20 kVA output capacity: Sized for medium-density rack loads. At 249 lbs, this is a floor-standing external unit — plan for dedicated floor space and confirm structural loading before placement in raised-floor environments.
- Multi-voltage AC input (120 / 208 / 220 V): Supports varied facility input configurations, reducing the need for external step-up or step-down transformers when integrating across mixed-voltage infrastructure.
- External form factor: Ships as a standalone external unit, which keeps the UPS serviceable without pulling it from a rack or cabinet — useful in environments where the UPS needs periodic inspection or battery work while the load stays live.
Integration & Compatibility
As part of the broader APC Smart-UPS line, the SUVTP20KF3B4S is designed to integrate with APC's EcoStruxure IT management ecosystem for remote monitoring, event logging, and runtime reporting. Verify specific network card inclusion and power management software compatibility against your current monitoring stack before ordering. For high-availability deployments requiring redundant power paths, consult the APC configuration guides for parallel and redundancy options within this power class.
Frequently Asked Questions
Q: What is the output power rating of the SUVTP20KF3B4S?
A: The SUVTP20KF3B4S is rated at 16 kW / 20 kVA output.
Q: What input voltage does the SUVTP20KF3B4S accept?
A: It accepts AC 120 V, 208 V, and 220 V input, accommodating common three-phase facility configurations without requiring an external transformer.
Q: Is the SUVTP20KF3B4S a rack-mount or floor-standing unit?
A: The SUVTP20KF3B4S is an external floor-standing unit. At 249 lbs, it requires dedicated floor space — it is not a standard rack-mount device.
Q: What UPS topology does the SUVTP20KF3B4S use?
A: It uses online double-conversion topology, meaning the load runs on inverter-conditioned power at all times with zero transfer time to battery during a utility event.
Q: Where can I find the full datasheet for the SUVTP20KF3B4S?
A: The full technical datasheet is available directly from APC by Schneider Electric at apc.com by searching the model number SUVTP20KF3B4S.
The SUVTP20KF3B4S sits in a power class that gets overlooked in favor of smaller single-phase units until someone actually adds up the load — a dense 2U compute row, active storage, and network core in the same room pushes past what a 3–5 kVA unit can handle. At 16 kW with online double-conversion, this unit is the right answer for that scenario.
Technical Highlights:
- Online topology, zero transfer time: Unlike line-interactive designs that switch to battery on a sag, double-conversion means the inverter is always driving the load — a complete utility dropout looks like nothing to the connected equipment.
- 16 kW / 20 kVA capacity: Enough headroom for a mid-density server row or a loaded security operations rack without running the unit above 80% — the standard ceiling for UPS longevity.
- Multi-voltage input (120 / 208 / 220 V): This flexibility simplifies integration in facilities with mixed panel configurations, a common condition in older commercial buildings undergoing IT build-outs.
Deployment Considerations:
- At 249 lbs, this is not a one-person install. Plan for a two-person crew, a pallet jack, and confirm the floor load rating — particularly important in raised-floor data rooms where point loading matters.
- Verify output connection type and confirm your PDU or hardwire termination matches before the unit ships — the SUVTP20KF3B4S product name indicates hardwired output, which requires a licensed electrician for termination in most jurisdictions.
The SUVTP20KF3B4S is well-matched to a security operations center or mid-density server room where a single managed UPS covering the full room load is preferable to multiple smaller units — simpler monitoring, one maintenance contract, and no inter-unit load balancing to manage.
