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
