Current Sensing Switch - Low Current - Adjustable (0.5A-2A)

The Powerform model ISNSE-LC-ADJ power sensing switch acts as an automatic on or off trigger for a secondary circuit, when it sense’s a load or current draw that exceeds it’s set rating.

The Low Current Adjustable (LC-ADJ) model can be used to sense a loads between 0.5 amps to 2 amps AC.

It is features two adjustable, front mounted engagement pots. This allows the installer to customise the on / off engagement points between 0.5 amp to 2 Amp.

The unit is suitable for use with both inductive and resistive loads.

The unit is simply connected in series with either the active or neutral line to the load being monitored.

When a load is detected above its set engagement point, the device will automatically switch on / off an independent control circuit or device up to 240 Vac 1200Va 5 amp.

The unit can monitor one or more items provided the maximum current and power ratings are not exceeded.

The unit features auto on when the load is greater than it’s set engagement point (+/-10%), and auto off when the load is less than the set disengagement point (+/-10%).

The unit "looks like" a light circuit to a standard run-on timer, and can safely work well with most run on timer types available on the market.

This then allows you to use a run on timer in conjunction with the ISNSE module, so that you application can be auto on/off, with extra run time via the timer, to allow sufficient extraction of hot / moist air after a process stops.

It is used typically as an add-on module in bathroom, range hood and other domestic, commercial and industrial applications to enable remote switching, when a low current set limit is exceeded.

For example the unit can be wired into a range hood application, so that it can engage a secondary device (damper, booster fan or similar) automatically when it detects the fan (subject to fan size / type), but not engage when the range hood lights are turned on.

The unit can also be used to trigger a C-Bus module, or HPM icontrol I/O module for load monitoring in building management systems (BMS).
