E1040 1A VOLTAGE SENSITIVE SWITCH - 13.1V Switch On (voltage rising)

Specification
This Unit provides a set voltage to switch a load of up to 1A.

The current drawn from the voltage source is < 1mA below the switching voltage.

The output switches On as the voltage rises and Off as the voltage falls.

The switch voltage can be set in the range 10.5V to 14.0V.

This Unit was designed to maintain the Cranking Battery threshold voltage of 12.5V – 13.5V, depending on the setting of the Voltage Adjuster (ie: to suit the application) thus retaining sufficient battery capacity to start the Vehicle.

The Unit also can be used as a Solid State 1A Relay.

The Unit can be used for switching higher power by adding a relay - SEE WIRING DIAGRAM BELOW
