Reviews For 50V4151

Internal Review

The 50V4151 is a newer regulator board version than the 50V4150 or 50V4140 and has some advanced parameters not available for prior versions. The Nema 1 cover is built of a hardy plastic that is much less likely to break or crack than the material used for smaller horsepower GV3000 drives. Overall, the 50V4151 is reliable and easy to program from the local 4 digit keypad. - AX Control Technician
