• Soft-start prevents nuisance tripping and prolongs element life.
• Easy to install.
• Can be installed indoors or out.
The Infresco-S 4kW is part of a family of controllers designed to provide energy saving when used with quartz halogen infrared heaters or other heating and lighting products. The ‘S’ soft-starts the load either automatically, when power is applied to the unit, or by the use of a remote switch (e.g. CC3 Time Programmer). Incorporates zero-voltage switching and a soft-start function to eliminate inrush current - potentially increasing heater element life by up to 30% and preventing nuisance-tripping on heavily loaded circuits. Installation of the unit is simple, and once installed is maintenance-free. The soft-start circuit is initialised each time power is supplied to the unit. Alternatively, a remote switch or heater time programmer can be added using terminals (INPUT COM) on the PCB. (in normal mode the terminals are fitted with a link, this will need to be removed and switch wires fitted).
