Built-in mains chargers for emergency vehicles with very different usage cycles
Especially in rescue and emergency vehicles, the reliability of the batteries installed in the vehicle is crucial for the operational readiness of the vehicle. Above all, if many permanent consumers put a heavy load on the batteries, there is no time for recharging due to frequent use, or the charger is insufficiently matched to the batteries. In order to meet the special requirements of emergency vehicles, the VAC series was created in cooperation with vehicle and leading battery manufacturers.
Votronic charging technology has been used in professional emergency vehicles such as fire brigades, ambulances and coastguards for years! Quality - Made in Germany - !
The device electronics are protected against moisture and ensure safe operation in the event of strong temperature fluctuations. Permanent consumers connected to the vehicle electrical system (radio devices, charging cradle, etc.) are also supplied without impairing the charging process. The built-in charging current distributor also automatically supplies the starter battery with full charging current if required. When the vehicle is connected to the mains, the engine start lock can be activated via a message output.
The devices are supplied with a temperature sensor 825 to ensure that the batteries are optimally charged. The installation position is variable, thanks to a second device label included in the scope of delivery. Instead of a remote control, a waterproof LED display (see accessories) can be connected to the Remote Control connection socket, which indicates the operational readiness of the device on the outside of the vehicle.
Other special features at a glance:
- Votronic products "Made in Germany"
- High charging capacity even over short distances
- Significantly improved energy balance of the on-board battery
- Optimal charging characteristics for all battery types adjustable with battery selector switch (lead-acid, gel, AGM, lithium LiFePO4)
- Suitable for all alternators
- Automatic, adjustable power control ensures that the starter battery is primarily charged by the alternator when the vehicle electrical system is heavily loaded, thus ensuring that the vehicle can be started again immediately
- Easy installation, no intervention in the vehicle's starter circuit required, device is connected to the charging line to the supply battery
- Parallel operation to increase performance possible
- Especially recommended for vehicles with the Euro 6 standard
- temperature sensor 825 already included
- The charging converters are also characterized by their compact design, low weight (high-frequency switching transformer, switch mode technology) and powerfully dimensioned power components. 6 operating displays provide information about the operating status of the device at any time.
