About the 1AC4103U

1AC4103U is a Reliance Electric GP-1200 drive controller. The voltage is 460 VAC, and the horsepower is 3 HP. The controller is UL listed and is enclosed in a NEMA 1 case. The weight of the controller is 11.5 kg. The controller has two LED indicators. The green LED is normally on and indicates that the controller is running. When the red IET light is on, a drive fault has occurred. When this light is on, the drive will be shut down. To troubleshoot the controller, first clear the fault and reset the controller. If the controller does not restart, follow the steps detailed in the user manual. Flowcharts illustrate how to assess and correct controller faults quickly, safely, and accurately.

The controller includes line transient protection, which prevents power line transients from harming the controller. The controller also includes standard fuses, line-to-line and line-to-ground output short circuit protection, an isolated START/STOP button, function loss circuitry, variable torque V/Hz curve selection, torque boost for increased starting torque, motoring current limit and regenerative voltage limit, local devices for speed, standard coast-to-rest on STOP or ramp-to-rest with a switch change, and IET on high D-C bus voltage. Standard Kit Options include the Local Operator’s Control Station Kit, the Remote Operator’s Control Station, the Consumer Interface Module Kit, the Dynamic Braking Kit, the Digital Meter with First Fault Indication, the Extended Line Dip Module Kit, the Output Frequency Meter, the Output Ammeter, the Output Voltmeter, and the Cabinet Conversion Kit (NEMA 1 to Chassis).
