Made in the USA
The Larson Electronics MPD-208D-45KVA-480D-2X30A power distribution substation converts 208V AC three phase electrical current into three phase 480V AC. This unit provides operators the ability to safely tap into and distribute 208V AC power from a variety of sources including generators and direct grid power.
Portable Power Distribution Purpose and Use
The MPD-208D-45KVA-480D-2X30A portable power distribution system gives operators the ability to power their 480 volt equipment from a single system. On the primary side, operators connect 208 volt via 20` of 2/4 Type W cord. On the secondary side, operators connect to two 460R7W receptacles for 480V equipment. All receptacles are protected by weatherproof covers.
Operation: A 20` 2/3 Type W cord brings 208V three phase power to the 200-amp, 208V disconnect, which is fused at 150 amps, and passes power to the transformer. The NEMA 3R 45 KVA transformer converts 208V three phase power to 480V three phase and passes the current to the secondary panel. The secondary side of the transformer feeds a NEMA 3R 125-amp main lug only panel. This secondary panel contains two 30-amp, 480V, 3-pole breakers protecting two 60-amp, 460R7W, 3P4W, 480V receptacles. With both receptacles fused at 30 amps (even though they are 60-amp receptacles), the maximum amps for the receptacles is 30 amps.
Protective Construction: Unlike many portable power distribution boxes made of plastic and utilizing thin gauge, low grade metals in their construction, this unit is designed for serious use and is ruggedly constructed to withstand demanding conditions and heavy duty industrial applications. The transformer and load assembly is mounted on a 3/16" thick carbon steel mounting platform and the load center/distribution assembly is mounted to the standard 2" x 2" x 1/8" square carbon steel tubing frame, resulting in an extremely stable, durable and well protected power distribution platform. This model is equipped with forklift skid pockets, locking polyurethane casters, and a top located lifting eyelet which allows easy lifting with cable or chain hooks. This can be replaced for an additional cost with stainless steel, hot dip galvanized steel, or aluminum depending on the customer’s needs. Larger units are available upon request and can be equipped with skids or trailer mounted.
Grounding: Transformer is grounded to the frame and we provide a grounding lug on the frame for the earth ground.
~Please check all motor loads for dual rated motors that will work 208 or 240.~
Applications: This power distribution system is ideal for indoor or outdoor use and applications including but not limited to, construction sites, plant maintenance, plant turnarounds, shows, exhibits, and shipyard operations. These power distribution systems are popularly used in applications where external power sources are often necessary. We also offer class rated transformers for use within explosion proof and hazardous location environments.
