Bridgetek MC-0301-01A Modbus Trailing Edge Light Dimmer
Bridgetek MC-0301-01A Modbus Trailing Edge Light Dimmer can be integrated with dimmable LED lamps for adjusting the percentage of light dimming. The Bridgetek MC-0301-01A features trailing-edge technology, which turns off the current at the end of the AC waveform. The operation is smoother, softer-starting, and silent. The light dimmer controls up to 550W at 240VAC or 230W at 100VAC for single-channel loading.
The Modbus Trailing Edge Light Dimmer provides a 2-digit display that shows the dimming percentage. Zero crossing detection determines whether the AC input frequency is 50Hz or 60Hz before enabling dimming. Additionally, an external dimmer controller can also be used to control light dimming.
