A simple but versatile device to switch a relay when its input voltage crosses a threshold. Use it to prevent a lead-acid battery from being over-charged or in automotive applications to trigger an extra fuel pump under high boost, anti-lag waste-gate shutoff for example. A PCB mount 12V DPDT relay is supplied but the circuit caters for other types depending on the voltage and current you want to switch. In conjunction with a standard battery charger and suitable resistor, the device can also be used to trickle charge a lead-acid battery.

Features:
* 5 - 24VDC operation
* Adjustable trigger threshold
* Trigger on high or low voltage
* Output state indicator LEDs
* Multiple relay options (Kit supplied with onboard relay)

Kit supplied short-form with double sided, solder-masked and screen-printed PCB, onboard relay and electronic components. Cabling and case not included. PCB size: 107 x 61mm

Optional relays:
24V 12V DPDT PCB Relay: SY-4053
30A 12V SPST Horn Relay: SY-4040
30A 12V SPDT Horn Relay: SY-4070
60A 12V SPDT Horn Relay: SY-4074
