These are General Purpose drives designed for use with Permanent Magnet or Shunt wound DC motors. NEMA 1 enclosed drives are suitable for most industrial applications. The NEMA 4X controls are best suited for washdown or outdoor installations or for extremely dusty applications. Chassis only drives are available for building into equipment, machinery or existing enclosures. Most controls have a dual voltage switch allowing the control to be used with either 115 volt or 230 volt, single-phase, input power at either 50 or 60 Hz service. It is important that the proper voltage motor be ...

One-way DC controls are designed to operate permanent magnet or wound field motors. If the motor's rotation needs to be changed, the armature leads need to be reversed. Some NEMA 1 and NEMA 4X controls offer optional switched for reversal. Stopping of a motor with a one-way control should be done by dynamic braking, some controls offer the Forward-Brake-Reverse switch for this purpose too. Features Full wave SCR control with free wheeling diode (NEMA type K) Field power supply allows use with shunt wound DC motors as well as permanent magnet motors Adjustable accel, decel, current limit, ...
