AVSPC12 Amber Valley Charge Guard Voltage Sensing Split Charge Device 12V 200A

Amber Valley Developments LLP Based in the UK, is an international speciality manufacturer of vehicle safety equipment. Amber Valley is one of the largest independent European manufacturers of reversing safety, vehicle battery and engine protection products in the commercial vehicle industry. They are constantly in the process of pioneering modern and innovative safety products which meet rigorous industry safety standards.

How It Works

When the engine is running, the Charge Guard senses the voltage and allows the charge through to the auxiliary battery. When the engine is switched off, the Charge Guard monitors the voltage from the starting battery into the unit. When the voltage drops to 12.5V (AVSPC12) or 25.4V (AVSPC24) the unit will separate and isolate both batteries. This means that equipment powered from auxiliary batteries cannot drain the starting battery.

Why You Need One

With today’s engine management systems and “intelligent” alternators you cannot use the charging light on the dash as a switch, also you cannot jump start most new vehicles without the danger of damaging the engine ECU. This unit then becomes cost-effective.

Who Uses Them

Emergency vehicles where battery drain is a problem. Utility and council vehicles where multiple beacons/work lamps or power tools are being charged.

The unit also has a one minute timer built in to eliminate damaging relay chatter caused by a flat auxiliary battery putting too much strain on the unit.
