About the 14C101-1U
Produced by Reliance Electric, the 14C101-1U is a ¼-¾ range HP Controller Model that accepts a control power input of 115 V AC. The device has a power supply input of 5000 and a maximum transfer KVA of 40.0. The device is a full-wave power converter without back rectifier, and features both an analog major and minor loop in order to regulate armature voltage and speed. This particular version of the series is one of the “complete” versions (as opposed to the “basic” version of the part).
The controller has a variety of functions, such as START/STOP, RUN/JOG, FORWARD/REVERSE, torque selection, speed selection, and isolation of armature voltage. The device is highly configurable, allowing users to adjust IR drop compensation, maximum speed, minimum speed, current limit, and acceleration and deceleration rates. In regards to safety, the device guards against automatic restarting of equipment after interrupted a-c incoming power is resumed. Additionally, the device isolates armature voltage and current feedback in order to assure the separation of regulator circuits and power.
