PCS PulseWorx UPB Wall Switch-Relay/Dimmer

The WS1C was designed to control 0-10V dimmable LED fixtures. It has a 15A rating relay built in, utilizing power relay control (PRC) technology, relay contacts send out signal to 0-10V LED driver to control lighting loads.

With most lighting transitioning to LED both in new installations and retrofit, installers need a method to change the illumination level of LED fixtures that is easy to install, works well, dims and brightens smoothly, and doesn’t suffer from strobing at low illumination levels.

When LED fixtures are installed in office or residential locations it is best to provide a way to change their illumination level for different usages of the space especially since LED lighting can be perceived as much brighter than the lighting it replaces. Common LED drivers have a 0-10V control signal as an input to the LED fixture to set its illumination level, where the voltage level is proportional to the illumination level.
