SmartFuse

The SmartFuse is an Battery Guard/Protect + „Fuse“ which can detect under voltage, over voltage, over current (overload) and disconnect the circuit. The voltage- and current values are programmable.

The SmartFuse can be used with a (little) remote switch as a Battery(Main)Switch.

Instead of three different individual products, you have with one SmartFuse reducing in costs in purchasing and installation time.

After shutdown (SmartFuse) the consumers by under voltage from the battery, the SmartFuse let charge current through to the battery from the charger, while load is disconnected. For example, by a “combi” inverter (inverter/charger/AC transfer switch combination) so that the battery can be recharged. Only when the “on” voltage has reached from the SmartFuse, then is it possible to get again current/power from the battery.

Properties:

  • Battery Guard/Protect which can detect under voltage, over voltage, over current (overload) and disconnect the circuit.
  • Programmable electronic fuse => Six current values 75-250A
  • To connect the equipment safely without any spark at the battery
  • Battery Main Switch=> Activate or de-activate the SmartFuse is possible with a (little) remote switch
  • After overload/over current shutdown=>Activation with a pushbutton
  • To prevent deep discharge of the battery => Four under voltage programs
  • Charging the battery is possible in case of under voltage shutdown (disconnecting user)
  • Reverse polarity protection of plus / minus battery
  • SmartFuse is fast with overload, normal fuse is slow. No sticking or burning in of contacts possible, likewise no sparks or oxidation of the contacts, as with large DC currents, by use a relay happens.
  • High overload capability (ideal for starting 'Serious' heavy load)
  • Over voltage shutdown (>16V@12V mode, >32V@24V mode)
  • Watertight IP67 housing

Delivery contains:

  • SmartFuse SF250A with mounting plate
