Battery Protector 100

• High switching current 100 A, short-time (2 sec.) overload up to 150 A is admissible, can be switched over to 12 V/24 V board mains supply
• Based on programmed characteristic diagrams of battery, the intelligent automatic switching threshold always calculates the disconnection point “empty” being appropriate for optimized capacity utilization and safe protection of the battery, from powerful consumers (low switching threshold at shorter response time) to very small loads (e. g. “hidden” current consumers with response times over days/months with high response threshold)
• Operation with 3 defined disconnection thresholds can be (manually) adjusted
• The higher set values are keeping the starting ability of intervention vehicles with only one battery circuit
  (according to DIN EN 1789)
• The preliminary alarm with visual (LED) and audible indication (beeper, can be switched-off), as well as a separate warning terminal (PNP, plus output, 0.2 A) allow to the user to take countermeasures in time
  (such as to disconnect consumers, which are not required)
• Solid threaded battery connections for cable lugs M6, inclusive cover for battery connections

Battery Protector 300

Operation as Battery Protector:

• Optical indication of the operating status by two LEDs
• Acoustic alarm can be activated (sounds when the pre-warning threshold is reached or when it is switched off)
• Output for external alarm display (max 0.3 A, short-circuit proof)
• Suitable for all common types of lead-acid batteries with 12 V or 24 V nominal voltage (lead-acid, gel, AGM,…)
• Suitable for Lithium batteries (LiFePO4)
• Additionally usable as a powerful battery main switch with protection function
• Various switching thresholds configurable
• With the EMERGENCY ON function, the shutdown can be canceled manually at any time

Operation as Switch Unit:

• Suitable as battery main switch
• Electronic delay prevents too fast response, e.g. at voltage drops by switching on strong consumers
• Optical indication of the operating status by two LEDs
• Alternatively, it can be used as a remote-controlled power relay („Switch Unit“), e.g. at LCD-Battery-Computer S

Start Alarm 124

According to DIN EN 1789 for intervention vehicles

The VOTRONIC Start Alarm 124 is an alerter with audible alarm (beeper) and visual alarm (LED) for the starter battery of intervention vehicles with only one battery circuit (according to DIN EN 1789, paragraph 4.3.2). The alarm shall warn the driver early of a battery, which is not capable to start.

An additional horn or similar alarm device can be connected to a terminal (PNP, plus output, max. 0.5 A). The reset to normal operation is effected automatically, as soon as the motor is running again. The unit is suitable for 12 V and 24 V operation and for all types and brands of lead batteries. The electronic system is protected against humidity; the connection is made in the rear terminal box.

The own consumption is below 3 mA (according to EN 13976). The intelligent electronic evaluation of the Start Alarm 124 avoids indication errors, such as in case of voltage drops.
