    Voltage Switch

    voltage switch

    Introduction:

    Want to trigger a device when a monitored voltage, temperature or light intensity reaches a certain value? The eLabtronics Voltage Switch is an incredibly easy way of doing it.

    The eLabtronics Voltage Switch is a brilliant device. It can be used to monitor the voltage output of existing sensors (accelerometers, pressure sensors, airflow sensors, etc) or by adding a few components, it can monitor temperature or light levels. You can automatically turn on cooling fans when it gets hot, operate a solar water heater pump, switch on lights when it gets dark, sound a low battery alarm, or even turn on a low fuel warning light in a car.

    Features:

    • Independent setting of set-point and hysteresis
    • Monitors input voltage range of 0.1 – 50V
    • Sensing direction: selectable for rising or falling
    • Hysteresis adjustable from 1 – 100 per cent
    • Output can be user-set to be fully on, pulse twice, or continuously pulse
    • Operates from 10 – 40V DC
    • Fuse and reverse polarity protected
    • Can be configured to automatically switch at certain temperature or light level
    • Output power: up to 10 amps continuous with appropriate heatsink, up to 15 amps short pulsed with appropriate heatsink, up to 100 amps with appropriately heatsinked external solid state relay
