APC Smart-ups SRT Step-down Transformer 10KVA Rackmount 4U 2X NEMA L5-20R & - SRT10KRMTF

APC by Schneider Electric SRT10KRMTF Step-Down Transformer 10KVA Rackmount

Overview

The SRT10KRMTF is a 10KVA rack-mount step-down transformer designed to bridge the gap between 208V building power and 120V or 240V AC equipment loads in commercial data center and server room environments. If your facility feeds UPS output at 208V but your connected equipment — servers, network gear, AV systems — demands standard 120V NEMA receptacles or 240V AC, this transformer sits in the rack and handles that conversion without requiring an external transformer cabinet or dedicated electrician-wired bypass panel. The unit occupies 6U of rack space, mounts in a standard 19-inch EIA rack at 17 inches wide, and terminates on the output side via hard-wire 4-wire (2PH+N+G) connection, meaning the output feeds a downstream panel or distribution unit rather than individual plug-in receptacles.

Key Features

• 10KVA Power Rating: At 10,000 VA, this transformer supports substantial mixed equipment loads — enough headroom for a fully populated server rack or a dense AV/security distribution stack. Sizing at 10KVA gives meaningful derating room when running at sustained real-world loads, reducing thermal stress on the windings.
• 208V Input / 120V and 240V AC Output: Converts single-phase 208V input — the standard output voltage of many double-conversion UPS systems — down to 120V and 240V AC on the output side. This makes it the correct interface device between an APC Smart-UPS SRT or similar 208V UPS and downstream 120V equipment that cannot accept 208V directly.
• Hard-Wire 4-Wire Output (2PH+N+G): The output terminates via a hard-wire 4-wire connection rather than standard receptacles. For permanent rack installations this is the right approach — it eliminates plug-rated current limitations, reduces connection resistance, and ties directly into a downstream PDU or breaker panel. Plan for licensed electrical work on the output side during installation.
