3U PDU Features

Product Overview

Quality products from Marway Power Solutions provide a solid foundation of reliable power distribution for any equipment set. For 30 years Marway has specialized in build-to-order and customized systems designed to save space and weight while meeting the unique needs of each application.

EMI Protection

EMI protection is provided by a power line filter. Noise and harmonics in the facility power lines can cause problems for sensitive electronic equipment. A filter in the PDU helps prevent noise and harmonics from reaching downstream equipment.

Surge Protection

Spike and surge protection is provided by metal oxide varistors (MOVs). Facility power lines can sometimes transmit a sudden increase in voltage. Even though the voltage spike or surge may be very short in duration, it can damage equipment. The MOV in the PDU clamps the line voltage so it cannot exceed a specified value, thus protecting any connected equipment.

Current Protection

Overcurrent protection is provided by one or more circuit breakers. Equipment faults can cause excessive power to be pulled from facility power lines. This can damage the equipment and power cabling. The circuit breaker in the PDU protects downstream equipment by opening the power line if too much current is being consumed.

EPO and Remote Control

The N.O./None remote type label designates a Normally Open Enable/no Disable interface for the remote operation of the PDU.

This remote EPO interface requires an external normally open signal to ENABLE the switched outputs in the PDU. The external ENABLE contacts must be closed to turn on the PDU outputs.

Our Universal Control Panels, are popular systems for providing remote on/off/EPO control of one or more PDUs.


This PDU includes a phase rotation interlock. The interlock monitors the relative phase rotation angle for a three phase circuit. If the phase rotation is incorrect, the interlock is triggered and the switched outlets in the PDU are turned off. The interlock automatically resets when the phase rotation is corrected.
