VSR A - ANALOGUE - 80A/160A - 12V/24V

New product

Sterling Power VSR A - Analogue (Voltage sensitive relay) with selection 12V or 24V and 80A or 160A. The relay allows simultaneous charging of two different batteries.Analogue (Voltage Sensitive Relays) VSR A are the most common VSRs on the market. They simple switch on and off between two preset voltages (on 13.3V and off 12.9V (x2 for 24V)) with a 30 second delay.

More info

They work fine for the majority of applications where you simply need to isolate two battery banks and charge the secondary battery (with 0.0V drop) when the engine is running.

They are not ideal in situations where there is a high current draw from the secondary battery and you are using exotic batteries such as AGM, Gel or Lithium where different voltage switching is required. Likewise, if you require unidirecitonal charging the analogue is not suitable, digital is required.
