Better safe than sorry: our reliable solutions for vehicles in the emergency services sector
LEAB develops and supplies reliable components for vehicles of authorities and organisations with security tasks. These include fire brigades, police and rescue services.
A reliable power supply is essential in these areas, and in many situations even vital. Systems with well-coordinated components are best suited for this. Here we show what these can consist of and which industry solutions we offer.

LEAB uses various components to ensure a reliable power supply under all conditions.

Power and compressed air supply
Full Power: The PowAirBox II
The PowAirBox II (PAB II for short) is a supply system that has been specially developed for rescue and fire service vehicles. It provides a power supply and at the same time a compressed air supply - in other words: charge maintenance for emergency vehicles.
With the 2nd generation of the PowAirBox, we have introduced sophisticated improvements to this industry solution. The optimisations include
Low installation depth (75 mm)
Sensor monitoring with start prevention
Wear-free automatic and manual ejection
Robust IP55 housing
Intelligent power electronics

Small but impressive: the MelfBox
Our MelfBox is ideal for supplying 230 V to special-purpose and utility vehicles. Thanks to its IP55 protection class, it is protected against moisture and dirt particles and can withstand use in challenging conditions without damage.
Delayed electrical activation and electronic disconnection of the load before disconnecting/unplugging the coupling prevent contact burn-off and significantly minimise wear.
Highlights:
Integrated start prevention
Dynamic status display
Protection class IP55

DISTRIBUTE
In the right place at the right time with the on-board power distributor
On-board power distributors act as a safe sub-distribution solution for single-phase AC voltage networks in vehicles. They are used when several electrical consumers are connected to an inverter at the same time.
Our on-board power distributors are equipped with personal protection switches as standard and are quickly installed. In addition, they are available with a variety of socket combinations and mains priority switching.

Insulation monitoring optionally available
Many different models available

CHARGE
TS Pro DC-DC-Charger – Flexibility and reliability compliant with DIN 14679:2024-02
Our new DC-DC charger TS Pro is specially designed for the needs of the fire brigade sector. The charger can be used universally in 12 V or 24 V vehicle electrical systems to recharge the starter batteries of generators or portable pumps. With five charging characteristics for all battery types and the option of measuring the temperature directly at the battery plus an additional power supply mode (AC adapter function), the TS Pro sets new standards in charging technology.

ABC series - Modern chargers for all vehicle electrical systems with lead batteries
You are on the safe side with our ABC series. The DIN 14679:2024-02-compliant chargers are modern installation solutions for the special vehicle sector, in which charging is fully automatic and microprocessor-monitored.
They are suitable for all vehicle electrical systems with lead-acid batteries and are available in protection class I and II with a charging current of 15 A to 120 A. Additional systems, such as temperature sensors or remote displays, can be easily connected. Thanks to 15 selectable charging characteristics, optimum and gentle charging is guaranteed for all variants.

Constantly compliant to standard
Reliability is particularly important in the fire service. Our battery chargers ensure that starter and auxiliary batteries are always supplied with plenty of energy - and strictly follow DIN standard 14679.

STORE AND SUPPLY
LPS II: The all-in-one solution
Mobile power supply is guaranteed with the LPS II - thanks to the integrated inverter, battery management, charging booster, automatic personal protection and more.
DC charging is possible not only from the 12 V, but also from the 24 V vehicle electrical system. Furthermore, the LPS II has a very low self-consumption. In addition, the integrated solar charge controller (MPPT) allows the battery to be charged effectively and gently and expanded with additional devices as required.

Lightweight and compact: DC-DC converters
Our PP series DC-DC converters easily convert your 12 V on-board power supply voltage to a 24 V on-board power supply voltage, for example for radios. The opposite direction is also easily possible.
The devices in the PP series are characterised by their compact dimensions and low weight combined with a high IP protection rating. This makes them a reliable solution, especially under difficult operating conditions.

Friend, helper, guardian
The BW 801e battery monitor is a two-stage safety system to prevent deep discharge of your battery. Acoustic and visual alarm functions warn you of an imminent deep discharge. If current continues to be drawn from the battery, the battery monitor disconnects the connected consumers from the battery to prevent deep discharge. It can be used in both 12 V and 24 V vehicle electrical systems.
