Remote Operated Battery Switch w/Optical Sensor
500A 12/24V
The MD range of battery switches allow you to install the battery switch very close to the battery, to remotely manage the increased electrical loads found on today's boats. This reduces cable lengths and sizes, providing significant savings in expense and weight of copper battery cable. They are ideal for remote isolation of bow and stern thrusters. The 720-MDO has been enhanced to offer easy standard installation, or advanced options capable of switching different voltage circuits from the main supply (for example: a 48 volt bow thruster with a 24 volt house supply). The optical sensor uses the same easy connection for standard installation and gives you the ability to control different voltage circuits such as 36 or 48 volts. It can be used to switch positive or negative lines and the main contacts can be isolated from the control circuit allowing operation via another battery source. This optical sensor also has low stand-by current draw (<5mA).
