Vehicle Charge Splitters

Cristec MOSFET splitters allow separate battery banks to be charged from a source, such as a battery charger or engine alternator, without the battery banks being electrically 'visible' to each other. Splitters act as electronic 'non-return valves' for DC power flow and MOSFET type are the most efficient technology available with essentially zero volt-drop.

Simple, Efficient and Reliable

The MOSFET Charge Splitter is the latest technology available and supersedes original Schottky Diode technology which suffers from high voltage drop across the input to output. Now, using MOSFET technology means our modern range of charge splitters are simple to fit and require no operator input. They operate automatically and they have no volt drop at normal operating parameters and insignificant volt drop at full current delivery. They are the most efficient choice for straightforward charge distribution.

Studer Voltage Sensitive Relays

Studer MBR battery separators are microprocessor controlled voltage sensitive relays. The VSR is installed between a ‘primary’ and a ‘secondary’ battery. When the primary is being charged from a charger or an alternator, the VSR automatically connects it to the other batteries in parallel. Whenever the charging process is interrupted, the relay automatically disconnects the two batteries, thus electrically isolating them. This prevents one of them being depleted by consumers connected to the other. The process includes time delays to prevent relay chatter from momentary volt drops and allows them to work in both directions.

They create insignificant voltage drop and have a special feature that they can also protect against any overvoltage which may damage sensitive devices.
