Portable Power Distribution Purpose and Use
The MPD-SS-500D-150KVA-4XTB-18X220V.16A-15X24V.16A-IND portable power distribution system gives operators the ability to power their 220 volt and 24 volt equipment from a single system. On the primary side, operators connect 500 volt line-in power via a customer provided cord. On the secondary side, operators connect to eighteen 220V pin/sleeve receptacles for their 220V equipment and to fifteen 24V pin/sleeve receptacles for 24V equipment.
Operation: A customer provided cord brings in 500V power to the NEMA 3R 225-amp, 600V primary circuit breaker disconnect and passes the current to the transformer. The NEMA 3R 150 KVA transformer converts 500V three phase power to 380Y/220V three phase and passes the current to the secondary panel. The secondary side of the transformer feeds a NEMA 3R 227.9-amp rated 380Y/220V MLO panel. This secondary panel contains two 60-amp and thirty 15-amp breakers, as well as four terminal blocks for 380V (two sets per box, two boxes) and indicator lights to display the status of phases during operation, and passes the current to a 24V single phase 100-amp rated MLO panel on the secondary side. This secondary MLO panel contains fifteen 15-amp breakers protecting eighteen 220V pin/sleeve receptacles and fifteen 24V pin/sleeve receptacles. All receptacles are equipped with weatherproof covers.
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. All panels are constructed of stainless steel. The power distribution unit is protected by a sturdy canopy.
This model is equipped with forklift skid pockets, locking 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.
Certification: Larson Electronics is a UL 1640 panel shop and certified to build portable power distribution systems. All units are built in accordance to NFPA 70 (National Electric Code) and certified to UL 1640. All equipment is NEMA 3R rated for indoor and outdoor use and provide a degree of protection against dirt, water, and ice. NEMA 4 and NEMA 4X equipment can be equipped upon request.
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.
