Larson Electronics LLC, an industrial lighting company headquartered in Kemp, Texas, has announced the release of its MPD-480-50KVA-24X120.20A-20C mobile temporary power distribution system. The distribution system powers three-phase 480-volt (480V) equipment on single phase 120/240-volt AC (120/240V AC) from generators and direct grid power and can be used in indoor and outdoor work sites such as construction sites and shipyards.
The 480V line-in power connects to the primary side to a 125-ampere (amp) 480V three-phase primary disconnect that contains three time-delay fuses protecting the 50 kilo-volt-ampere (KVA) transformer. The 480V current is then converted to 120/240V AC and passes through the secondary panel that contains 24 20-amp 120V breakers that protect 24 panel mounted 120V 20-amp 5-20R duplex receptacles equipped with weatherproof covers.
This portable power distribution system is designed for use in heavy-duty industrial applications and demanding conditions. The assembly is grounded onto a carbon steel platform with a carbon steel tube frame designed to protect the transformer from damage. Forklift skid pockets, locking polyurethane casters and an eyelet on the top of the frame is designed to make the distribution system easy to lift with cable or chain hooks. The frame can be replaced with additional materials upon request. The system is certified to UL 1640, and all equipment is National Electronic Manufacturers Association (NEMA) 3R rated for indoor and outdoor usage protecting against dirt, water and ice.
"Reliability, durability and safety are crucial for power distribution systems, especially when you’re dealing with the outside elements," Rob Bresnahan, CEO of Larson, says. "This is why we ensure our indoor/outdoor transformers are engineered to perform under rugged conditions and protected from potential damage by steel barriers."
