Power Timer

• Programmable disconnect time limit, 15 minutes to 8 hours, so that you can match your auxiliary load use to battery capacity, providing maximum run time yet still ensuring adequate reserve for engine start
• Prevents dead batteries due to accessories being left on and forgotten
• Once power off circuit is activated, power to auxiliary circuits is automatically restored when engine started, no delay in use of equipment
• Low and High Voltage Disconnect
• Simple 3 wire installation:1) Power in from battery, 2) power out to loads, 3) chassis ground. Optional ignition sense wire resets power on without having to start engine
• Rugged construction, plastic case with epoxy potted components, designed to withstand heat and vibration of engine compartment applications, and perform in demanding emergency vehicle applications
• 30 amp rating: Power timer can be applied to multiple auxiliary loads/circuits. Multiple devices can be left on during emergency calls without running engine
