Larson Electronics has added to its extensive range of industrial grade lighting equipment with the release of a mobile distribution system that steps down 240 volts AC electrical current to 120 volts AC.

The MDC-240-100MB-1X240.30A-1X240.50A-6X120 temporary power distribution system from Larson Electronics provides a safe and reliable way for operators in industrial settings to tap into and utilize power sources independently of the work area. This unit provides an effective power distribution system for operators performing plant turnarounds, maintenance and cleaning in hazardous areas, equipment installations and repairs, and any activities requiring an alternative to native power sources. The portable transformer is designed to operate with 240 volts 60Hz which it then steps down to 120 volts. The power distribution system on this portable substation makes 120 volts AC available with six 20 amp, 120 volt GFCI protected 5-20 duplex receptacles with weatherproof covers. This system also makes 240 volts available through one 30 amp and one 50 amp receptacle.  

Fifteen feet of #6/4 Type-W line in power cord is included to connect the substation to a primary 240V power supply. An eight foot copper ground wire provides operators the ability to ground the panel via grounding rod. The main load center is protected by a 100 amp load center with main breaker for circuit protection. The 120 volt line out protection is provided by eight 20 amp, 125 volt, 1 pole breakers. The load center is mounted within a NEMA 3R enclosure. The transformer and distribution assembly is mounted to a standard upright steel dolly cart style frame resulting in an extremely stable, durable, and mobile power distribution platform. Two run-flat tires and a cart style mounting platform provides easier substation mobility. This temporary power distribution solution can be modified to meet the needs of job-site receptacle requirements. This power distribution system conforms to UL 508A and is NEMA 3R rated and ideal for indoor and outdoor use.

“This power distribution system is mounted to a dolly style cart for ease of transporting the unit from one location to another,” said Rob Bresnahan with “Featuring a compact design, this system is ideal for applications such as construction sites, plant maintenance, shows, exhibits, and shipyard operations.”
