Sterling Power ProLatch R – Voltage Controlled Protective Relay

€149,80 - €174,80
Tax included.

Never again a dead starter battery or a deeply discharged leisure battery: The ProLatch R automatically disconnects your batteries from consumers as soon as the voltage falls below a programmed limit. This ensures there is always enough energy for engine starting – and your batteries are protected from permanent damage due to deep discharge.

Tip: Set the shutdown value for starter batteries rather conservatively – this way you will still have enough reserve for the next engine start, even with unexpectedly high consumption.
