The IMM01 Immersion Heater Power Halver is designed to halve the power consumed by standard 1-2kW 230V AC immersion heaters. When using the IMM01, the 1kW heater effectively becomes 500W. This ensures the current consumption limit from the mains when a boat is moored is not exceeded. The device is rated at 240V, 6A. The device is simply connected in series with the immersion heater, and to bypass the IMM01, a switch can be connected across the module. The IMM01 possesses thermal and over-current protection and is hermetically sealed in epoxy resin in an ABS enclosure.
