Solid State Function Modules
Solid State Function Modules - Snap onto a 22.5 relay or contactor
Converter - Converts an analog 0-10V signal to set the power of a load as a percentage depending on an input signal.
Load monitoring - Monitors a load circuit which is connected to the semiconductor switching device. Detected faults are LED indicated and a digital output is available. Basic Module - 6 sub loads, Enhanced Module - 12 sub-loads
Power controller - Combines the functionality of the Converter and the Load Monitoring modules into one module.
Power controller using P control: Maintains the power when the voltage or the load resistance changes.
Soft start current limiting: Limits inrush using phase control, with an adjustable voltage ramp. For applications such as lamps which have a high inrush current.
