Remote On/Off Circuit The remote on/off circuit eliminates the need for a high current switch on the input wiring. The remote on/off connection can be controlled by a power-saving switch or by the motor's run/stop switch (see manual). Adjustable output voltage: can also be used as a battery charger For example, to charge a 12 volt starter or auxiliary battery in an otherwise 24 volt system. All models are short circuit proof and can be connected in parallel to increase the output current. An unlimited number of units can be paralleled. IP43 Protection: When installed with the screw terminals facing down. Screw terminals: No special tools are required for installation.
