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.
PDU family MPD 920 is a variation of the MPD 520 family, but with the addition of Marway’s RCM control feature. This feature allows individual on/off control of each outlet through Ethernet and serial remote interfaces. All models include a 1U x 16.0" chassis and are designed for single phase AC power.
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.
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.
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.
Sequencing is a feature which turns on the PDU outlets in a predetermined order to help reduce inrush current. First one group of switched outlets turns on, and then after a brief time delay the next group of switched outlets turns on.
Marway’s RCM feature adds intelligent control capabilities to the PDU. This feature is used to remotely switch the outlets on and off via Ethernet and serial interfaces. For a detailed description of capabilities and interface protocols, see the PDU Software page on Marway’s website.
