25V4151

Product Description

The 25V4151 is a 25HP 380-460 VAC 3-Phase GV3000 series Reliance Electric AC Drive. Baldor Reliance and ABB could’ve also produced this drive depending on its production dates.

The 25V4151 is a PWM drive that is 50/60Hz and 35 KVA. It has the capacity to provide both vector and volts/hertz regulation for the drive. It has a typical output amperes of 39 and input amperes of 44. It has a full load loss of 800 watts. This drive is 376 mm wide, 605 mm tall, and 350 mm thick. It weighs 23.6 kg. This drive uses a 70A rated fuse.

The 25V4251 is covered by a NEMA 1 chassis. It is vented with a covered communications port that allows access to an RS-232 port. For efficient and safe drive use, please ensure that this chassis is not exposed to oil, coolants, airborne contaminants, and corrosive materials. No other devices should be mounted behind this drive.

While a generally reliable indoor drive, the GV3000 series 25V4151 may encounter the occasional fault of function. One fault that may effect the 25V4151 owner during installation or use is the acceleration overcurrent fault, signified on the drive's built-in keypad display with the code OCA. This fault is typically caused due to too short of a drive acceleration time, and can be ratified correctly by increasing the acceleration time parameters at P.001, P.017, and P.021. For more information on GV3000 series fault troubleshooting and corrective actions, the manual D2-3359-6 is a quite helpful reference.

To mount the 25V4151, use the four factory drilled holes on the back of the chassis. Mount it vertically to a panel or flat surface and use four M8 or M10 bolts and washers to obtain a tight mount. These bolts and washers do not come with the drive and are sold separately. All wiring to the drive should meet local and NEC/CEC codes. The wiring going into the drive is routed through a signal control terminal strip, a signal control or snubber resistor braking, and an input power and motor lead. The regulator board has a terminal strip that allows for I/O to be wired in and just below that is a power terminal strip.
