Series 183 and 184 Drives


The Snap-Trol Series 183 & 184 are full wave DC drives designed for light to middle duty OEM industrial applications where cost effectiveness without sacrificing the quality or performance of the unit is the key. The 183 & 184 have state-of-the-art features while maintaining industry standard mounting and adjustment configurations. The 183, which is U.L. recognized, controls 1/50 up to 2 HP DC Motors (with the appropriate heatsinking). It’s dual input line voltage does not require any internal changes to the drive when line voltage is changed from 120 to 230 VAC. The drive is capable of running 90 VDC motors on a 230 VAC line. This eliminates the possibility of having the unit jumpered for one voltage and applying another, causing the drive to be destroyed. The 184 can control 1 HP to 3 HP DC motors at 120 VAC or 230 VAC. This unit offers one standard package with no need to add heatsinks when an increase in horsepower is required. Connections to both models are 1/4″ quick connections.
