Product Description

The 0-56950-50 one of a few boards that comprise a 50HP 460VAC GV3000 drive. The 0-56950-50 unit is a printed circuit board that serves as the power supply board for 50HP GV3000 AC Drives. It can be installed in a variety of 50HP 460VAC models with varying NEMA ratings and regulator board versions.

The 0-56950-50 board is responsible for keeping both the internal power supply regulated and stable throughout the GV3000 AC Drive, to ensure that all of its component materials are distributed with equal amounts of power. It is built for the maximum distribution of up to 15 volts of direct current.

The 0-56950-50 board is incredibly important to ensure that the many other regulation functionalities of the other PBC components are achieved. Several of the GV3000 Drive’s input and output nodes require a sourced power supply from an internal source, or one from an external plug in. The Form A and Form B contactor points are rated for a 5 ampere resistive load, at a rate of up to 250 volts of alternating current, or 15 volts of direct current. The analog output requires a scaled voltage, ranging from 0 to 10 V/DC. The intake becomes proportional to that of the drive’s controlled motor speed and torque.

The 0-56950-50 Power Supply Signal board is reconditioned by AX Control Inc.’s on-site staff of repair technicians. We offer an automatic warranty upon purchase.

Reviews For 0-56950-50

Internal Review

The 0-56950-50 is an impressive power supply board used in dozens of 50HP 460VAC GV3000 drives. The fact that it can be installed in so many different models makes it valuable and multifaceted. Installation is easy as it only requires two ribbon cables to be reattached and a few fan cables as well. If it does become faulty, this is usually apparent via burn marks on the PCB. Reliance Electric did an excellent job with the 0-56950-50 and with GV3000 drives in general. That is likely why they continue to have a large installed global base. - AX Control Technician
