RS PRO Power Controller, Current, Voltage Input, 25 A

RS Pro single phase power controllers are designed to control the load power in function of the input control for resistive and resistive-inductive loads, for automatic temperature control systems in electrothermal devices. The power controller is a contactless power energy electronic device which includes a thyristor connector and electronic gate trigger system (GTS). This allows the change of power delivered from the AC voltage source to the electric energy load in the function of the analogue or pulse driving signal value.

• Universal/User selectable input 0/20mA, 4/20 mA, 0/5V, 0/10V
• Trigger deceleration of soft start type,
• Control of the initial trigger angle value,
• Control of the input line amplification,
• Trigger stoppage by an external signal,
• Wall mountable
• Control mode: on/off (similar to solid state relay), pulse and phase
• Amplification of input control signal (SPAN)
• Limitation of load current
• Overload protection
• Relay outputs
• Signalisation of exceeding the maximum temperature of radiator
• Control of 3 phase load (requires 2 x power controller units)
• IP10 (terminal side) and IP20 (casing side) protection

• Electrical furnaces and drying constructions
• Devices of mechanical engineering
• Production of glass and glazing
• Chemical and petroleum industries

In the case of phase control, the controller meets the requirements of electromagnetic compatibility in terms of noise emissions, only when working near the transition of the supply voltage across zero.
