Critical Velocity Enterprises, LLC ConstantCurrent PWM Resistive Controller RLC-230

The RLC-230 is a second-generation constant current PWM controller designed for resistive (non-inductive) loads. The control input is via any 5k potentiometer or 0-5V control signal, and the resulting output is a variable 0-100% pulse-width modulated voltage. The controller features two modes of operation: Current Limiting: the maximum allowable current is limited by the onboard trim potentiometer Constant Current: where the current level is controlled by the external pot, and the full scale range from 0 - 30 Amps is selected via the onboard trim pot. Sophisticated algorithms ensure safe operation through automatic fault detection and onboard diagnostics, overload protection, over-temperature protection and reverse polarity protection. Features: Use a 5k pot or 0-5V analog input signal for control Built-in power relay with option for external control Automatic Soft Start ramps up to full power when first powered up to decrease stress on power supplies. Two modes - current control and current limiting Over current protection Over temperature protection Over/Undervoltage protection Reverse polarity proteciton Automatic fault detection and diagnostics 5 low resistance MOSFETs for up to 99% efficiency Ultra-High efficiency design does not require heatsinks Specifications: 30 Amps continuous current 12 V nominal (11-15 VDC) operation PWM Range: 0% - 100% Connections: 0.25 inch quick-connect terminals for power connections Terminal blocks for signal connections
