APC by Schneider Electric SURT20KRMXLT-TF5 20KVA 208V Rackmount UPS
The SURT20KRMXLT-TF5 is APC's Smart-UPS RT 20KVA unit built for high-density rackmount deployments running 208V infrastructure — the kind of load-critical environment where a power event means downed servers, offline security systems, or halted production. At 20KVA and 14U of rack footprint, this is a centralized power protection device sized for small data centers, communications rooms, and enterprise equipment closets that need both meaningful runtime and a high outlet count under one chassis.
Key Features
- 20KVA / 208V Output: Sized for racks carrying servers, NVRs, switches, and networked infrastructure simultaneously — 20KVA gives you headroom beyond the average enterprise equipment room load so you're not redlining the UPS during peak demand.
- 14U Rackmount Form Factor: Installs directly into a standard 19-inch rack. The rack-mount profile keeps power protection co-located with the equipment it protects, eliminating the cable runs and single points of failure that come with remote tower UPS deployments.
- 17 Output Receptacles (12x NEMA 5-20R, 4x L6-20R, 1x L6): A mixed outlet bank covers both standard NEMA 5-20R loads and the L6-series twist-lock connections common on higher-draw 208V devices. You're not forced into a PDU layer just to plug in a mix of equipment.
- Maintenance-Free Sealed Lead-Acid Battery: The sealed, suspended-electrolyte design is leakproof — suitable for vertical or horizontal rack installation without the ventilation and containment concerns that come with vented battery chemistries. No routine electrolyte maintenance required.
- Web/SNMP Management Card Included: Network management comes in the box, not as an add-on purchase. That means remote monitoring, load reporting, and graceful shutdown scripting are available from day one without sourcing an additional accessory card separately.
- Smart UPS Signalling RS-232 Interface: The included RS-232 cable supports legacy server shutdown signalling — relevant in mixed environments where older servers or appliances rely on serial UPS communication rather than USB or network-based protocols.
- Rack Mounting Support Rails Included: Rack rails ship with the unit. In high-bay equipment rooms where sourcing compatible rails after delivery introduces delays, having them bundled eliminates a common installation bottleneck.
Integration & Compatibility
The SURT20KRMXLT-TF5 is designed around standard 208V rackmount infrastructure. The included Web/SNMP Management Card enables integration with network management platforms that support SNMP traps — applicable to most enterprise NMS environments. The RS-232 signalling cable supports UPS-aware shutdown on systems with compatible serial interfaces. For deployments running rackmount power protection alongside IP security, network, and compute loads, the mixed outlet bank (NEMA 5-20R for standard loads, L6-20R twist-lock for higher-draw 208V equipment) reduces the need for supplemental PDU hardware in the rack. The APC by Schneider Electric Smart-UPS RT line is a well-established platform in data center and communications room environments. Pair with compatible network switches and NVRs to build a fully protected security and IT infrastructure stack.

Frequently Asked Questions
Q: What outlet types are included on the SURT20KRMXLT-TF5?
A: The SURT20KRMXLT-TF5 provides 12x NEMA 5-20R, 4x L6-20R, and 1x L6 output receptacles — a mixed bank supporting both standard and twist-lock 208V connections across a wide range of rack-mounted equipment.
Q: Does the SURT20KRMXLT-TF5 include a network management card?
A: Yes. A Web/SNMP Management Card is included in the box, enabling remote monitoring and SNMP-based integration with network management systems without a separate accessory purchase.
Q: What battery type does the SURT20KRMXLT-TF5 use?
A: It uses a maintenance-free sealed lead-acid battery with suspended electrolyte — a leakproof design that does not require electrolyte maintenance and is safe for standard rackmount installation orientations.
Q: How many rack units does the SURT20KRMXLT-TF5 occupy?
A: The SURT20KRMXLT-TF5 occupies 14U in a standard 19-inch rack. Rack mounting support rails are included in the box.
Q: What are the physical dimensions of the SURT20KRMXLT-TF5?
A: The unit measures 62.2 cm H x 43.2 cm W x 77.3 cm D (approximately 24.5 in x 17 in x 30.4 in), sized for standard rack cabinet depths common in enterprise installations.
The SURT20KRMXLT-TF5 stands out in the Smart-UPS RT line specifically because of its mixed outlet bank — 12x NEMA 5-20R alongside 4x L6-20R and 1x L6 at 208V. In practice, that combination means you can protect a heterogeneous rack (standard servers on 5-20R, higher-draw storage or networking gear on L6-20R twist-lock) from a single 20KVA source without bolting a separate PDU into the rack just to adapt outlet types.
Technical Highlights:
- Mixed Outlet Bank (17 receptacles): 12x 5-20R plus 4x L6-20R plus 1x L6 under one 20KVA / 208V chassis — fewer PDU layers needed in mixed-load racks.
- Web/SNMP Management Card (included): Ships in the box, not as a paid add-on. SNMP integration means your NMS can pull load data and trigger graceful shutdowns without a technician on-site.
- Sealed Lead-Acid Battery (suspended electrolyte): Leakproof chemistry eliminates the containment and venting concerns common in equipment rooms — install it and leave it without scheduling electrolyte checks.
Deployment Considerations:
- At 14U, the SURT20KRMXLT-TF5 consumes a significant share of a standard 42U rack — plan your rack layout before ordering if cabinet space is constrained.
- The RS-232 signalling cable covers legacy serial-interface servers, but modern deployments running USB or network-only UPS shutdown should verify their management software supports the included interface before relying on graceful shutdown.
This unit fits best in a dedicated communications room or small data center running 208V infrastructure where the load mix genuinely spans both standard NEMA and L6-series twist-lock equipment — the outlet diversity is the deciding factor over simpler single-type 208V UPS options in the same power class.
