FAQs
When installing the V48M28T09NV, plan for a three-phase 480 V input with 208Y/120 V outputs, and allocate space for a 16.5 in length by 23 in width by 32.02 in height footprint. The unit is DT-3, totally enclosed non-ventilated, with aluminum windings and a 260 lb weight, which supports mounting on standard frames and minimizes ventilation requirements. Include primary protection, appropriate clearance, and accessible voltage taps (+/− 2.5%) for voltage compensation.
This transformer provides a 9 kVA rating with a 480 V primary and 208Y/120 V secondary, suitable for powering multiple control circuits or small motor starters. Operates at 60 Hz with a 150 °C rise rating. Taps include 2 at +2.5% FCAN and 4 at -2.5% FCBN, enabling minor voltage adjustments to compensate distance and load variations without rewiring.
Yes. The unit is a Totally Enclosed Non-Ventilated (TENV) dry-type transformer, designed for dusty or space-constrained environments. It carries UL Listed certification, which provides third-party safety verification. For regional compliance, verify CE or IP requirements with your local codes and Eaton datasheets; regional certifications may vary by market.
Common applications include powering machine control panels, OEM equipment enclosures, and small distribution blocks within manufacturing plants. Its DT-3 dry-type design, compact footprint, and voltage-tap options support reliable power for PLCs, relays, sensors, and control circuits in space-limited panels, reducing wiring complexity and improving maintenance efficiency.
The transformer is backed by Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, rely on the dry-type, sealed enclosure to minimize dust ingress, inspect connections periodically, and verify tap settings during commissioning and after long cable runs or load changes to maintain voltage accuracy.
