Larson Electronics 25 KVA Power Substation - 480V to 120/240V 1PH - (12) 125V 5-20R Duplex Receptacles - Rotary Switch

Made in Texas The Larson Electronics MPD-DC-25KVA-480.240.208-120 power distribution substation converts 480V AC electrical current into single phase 120/240V AC. This unit provides operators the ability to safely tap into and distribute 480V AC power from a variety of sources including generators and direct grid power. *PLEASE NOTE: ANY FREE SHIPPING OFFERS DO NOT APPLY TO POWER DISTRIBUTION PANELS, TRANSFORMERS, OR SUBSTATIONS* Portable Power Distribution Purpose and UseThe MPD-DC-25KVA-480.240.208-120 portable power distribution system gives operators the ability to power their 120 volt equipment from a single system. A rotary switch on the transformer is available for selecting the desired input voltage (480V, 240V or 208V). For safety, only one source disconnect on the primary side can be switched on at any given time. The disconnect being used to bring in the desired input voltage must match the selected input voltage on the rotary switch (and vice versa). On the primary side, operators connect 480 volt, 240 volt or 208 volt line-in power via a customer provided cord. On the secondary side, operators connect to twelve 5-20R 125V duplex receptacles for 120V equipment. Operation: Customer provided line-in cords bring 480V three phase power to the NEMA 3R 100-amp, 480V three phase primary disconnect, which contains two 70-amp time delay fuses; or 240V three phase power to the NEMA 3R 200-amp, 480V three phase primary disconnect, which contains two 125-amp time delay fuses; or 208V three phase power to the NEMA 3R 200-amp, 480V three phase primary disconnect, which contains two 150-amp time delay fuses, and passes the selected input voltage in single phase through to the transformer. The NEMA 3R 25 KVA transformer converts the selected input voltage to 120/240V single phase and passes the current to the secondary panel. The secondary side of the transformer feeds a NEMA 3R 125-amp, 120/240V single phase main lug only panel. This secondary panel contains twelve 20-amp breakers protecting twelve 20-amp, 125V 5-20R duplex receptacles. 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 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.
