with a single
-phase
supply power of either 120 Vac, 110–240 Vac, or 200–240 Vac.
Each PDU receives mains power through an inlet located at the rear. Power is distributed to all outlets on one or two
branches depending on the model. A variety of inlet and outlet connectors is available.
All models include a circuit breaker, indicator, surge suppression, and Marway’s RCM

. Additionally, three options of inlet power monitoring with digital display,
a remote on/off/EPO control bus, and an integral EMI filter are available in a variety of combinations.
All models are constructed of a steel chassis, and designed for fixed mounting within a 1U rack space in an EIA-310
compliant rack enclosure.
