The IRCLIM10 is intended to limit the large transient current occurring when a mains transformer is first energized. The inrush current of the transformer is limited by means of a triac, switching an ohmic resistor in series with AC mains ("Softstart") prior to switching full AC mains with a relay ("On").

The IRCLIM10 is controlled by either a pushbutton or a switch (jumper selectable mode). The IR receiver module IRRXMOD optionally may be used to control the IRCLIM10 by virtually any IR remote control.

The IRCLIM10 can switch multiple transformers up to a total switching power of 1500VA, the standby power consumption is below 1W.

A NTC thermistor optionally may be connected to the IRCLIM10 to ensure overtemperature shutdown, whereby the shutdown temperature is determined by the NTC specifications.

LEDs may be connected to the IRCLIM10 to indicate the status "Standby", "Softstart", "On" and "Overtemperature".

In conjunction with an appropriate mains transformer and the power supply PSACDC18, the IRCLIM10 is perfectly suited for mono or stereo power amplifiers including one or two Class-D audio amplifier module(s) CLDP500.
