Product Description
The 125R4160 is a 100-150 HP 380-460 VAC 3-Phase GV3000/SE AC Drive Controller that was originally designed by Reliance Electric. Depending on when its production dates were, it could have been also made by ABB or Baldor Reliance.
The 125R4160 typically uses a standard V/Hz regulation but it has the ability to change it to a vector regulation. Under the standard regulation it is rated 125-150 HP 170KVA with an output amperage of 210, 168, or 126 A (depending on what kHz it’s using). It has an input amperage of 213 and a full load power loss wattage of 3200. When the controller is using vector regulation it is 100-125HP and 127KVA. It has an input amperage of 159A and depending on the kHz rating an output amperage of 152, 122, or 91 amps. A 250A rated fuse is recommended for this controller.
The 125R4160 uses a NEMA 1 type enclosure. It weighs 96 kg and is 465 mm wide, 1457 mm tall, and 355 mm thick. This enclosure is very tall and has air vents on all sides. On its bottom, the enclosure has two large fans to help keep the air flowing to all of the controller’s internal components. On the bottom and top of the enclosure, there are brackets to panel mount the controller.
The 125R4160 has many internal components that come standard. It has fans that have wire harnesses, a keypad membrane switch that has a mounting bracket, a regulator PCB, a power module interface PVC and fuses that go with it, a thyristor firing pulse PCB and fuses that go with it, a gate driver PCB, two 24V DC fans, bus clamps, intelligent power modules, thyristor precharge modules, a current transformer, a ground fault transformer, and an output reactor.
