The BlueCool Soft Start module from webasto reduces short-term, high starting currents that can occur when starting the air conditioning system by up to 70 % and thus ensures a stable 230 V on-board AC voltage. This enables trouble-free operation even in an AC network with weak fuses (e.g. at the dock). The integrated, self-adjusting software adapts to the compressor type and supply frequency and permanently monitors the supply voltage to protect against possible undervoltage and a blocked rotor. The Soft Start module can be easily added to your existing setup by installing in the electronics box of the air conditioner. Suitable for air conditioners with 5,000 - 13,000 BTU/h. Operating voltage: 230 V 50/60 Hz.
