Step-Down Transformer for 5kVA UPS

The APC Smart-UPS Ultra SRTL5KRMTF converts 208 V input to 120 V output for rackmount or tower setups. It attaches above a compatible SRTL 5kW UPS to power 120 V equipment from an existing installation. The unit delivers 5000 VA capacity in a 2U form factor.

Rackmount or Tower Mounting

The chassis measures 30.5" D x 9.0" H x 23.5" W and weighs 223.0 lbs for stable rack or floor placement. Twelve NEMA 5-20R outlets are grouped with 15 A thermal circuit breakers: two banks of four sockets and two banks of two sockets. Installation requires vertical space above the UPS.

Outlet Groups with Circuit Protection

Four independent breaker groups protect connected loads from overload without shutting down the entire unit. The 120 V output feeds standard North American plugs directly from the transformer. No additional accessories or software are bundled with this model.
