The Kussmaul Power Timer, Model TMR-30KE P/N 390-0030-5, eliminates dead batteries caused by power drain from radios and data terminals that operate while the engine is off. The unit allows the use of accessory loads per programmed time limit while preserving the battery for starting the engine.
The Power Timer is programmable, ensuring adequate reserve to start the engine. Rugged construction, powder coated case with epoxy coated components, and water proof time-out setting switches, the unit is designed to withstand 80°C and the vibration of the engine compartment. The 30 amp rating permits powering multiple auxiliary loads/circuits without running the engine.
Features
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 the engine is started. Optional ignition sense input resets power ‘on’ without having to start engine; no delay in use of equipment
