Unirom’s Power Transformer Unit is an EPDU providing global electrical interconnectivity between the utility and critical process tooling. Input voltage: 440/400/220/208 VAC 3 phase Delta connection. Output voltage is 208/120V Wye connection. The output rating of the PTU is 30 Amps per phase (120 VAC per phase).
Output breaker includes GFI protected set at 30 mA. A PLC communication provides monitoring for operational safety which includes temperature, phase faults, smoke detection, and controller communication. The enclosure is IP22 rated. The system is designed to be either a stand-alone voltage conversion or can be integrated with a UPS.
The PTU consists of an ultra isolation transformer with grounded internal shielding between primary and secondary windings.
