The 3-digit, 7-segment LED display allows real-time monitoring of control input, load voltage, load current, load power, load resistance, and heat-sink temperature without requiring connection to an external display device.
Error messages (displayed on screen) and alarm indicator (ALM) will blink simultaneously and notify the users if there are operation errors such as diode error, overcurrent, overvoltage, fuse break, heat-sink overheating, or heater disconnection.
The fuse in the power controllers can be replaced easily just by removing a few bolts.
