The 6kW Soft Start controller is designed to reduce the impact on heaters and electrical circuits of high startup currents that occur when full power to the heaters is switched on instantly.
High inductive loads or “Inrush currents” caused by switching on high power equipment instantly can cause damage to the heaters and can also cause nuisance tripping of circuit breakers. Using a soft start controller will eliminate nuisance tripping and prolong the heater’s life due to the gentler start-up time.
The controller works by gradually applying full power over 5 seconds after the current is first detected by the controller.
The unit can work passively by waiting until the current is detected and soft-starting the heater. This makes it ideal as part of a large installation of heaters where a central control such as a thermostat switches several heaters on and off and the soft-start just responds when it detects the current. Alternatively, a simple switch can be connected to the unit to activate the current directly to the unit, making it ideal for smaller or domestic installations where the heater can be switched on directly via the soft-start control. This gives operators a lot of flexibility in how they want to design and control their heating system.
