LED dimmer for low-voltage lighting control

Opto 22 has unveiled what it describes as a compact, solid-state and networkable LED dimmer that uses pulse width modulation (PWM) to control LED brightness (0-100 percent) for 9-30VDC constant voltage LED lighting assemblies such as lamps, bulbs, strips, ropes and bars. The Network LED Dimmer can be used alone or teamed with other dimmers and is geared for any application that requires variable light from LEDs.

Lighting designers, facility engineers and architects can use the dimmer in applications such as stage or accent lighting, LED color mixing, path marking, backlighting and facade or wall lighting. When connected to an RS-485 serial network, multiple network LED dimmers can be integrated into a lighting, automation, or building control system that supports DMX512-A, Modbus/ASCII, or Optomux network protocols.

The Network LED Dimmer is also suited for vehicle and vessel applications, where the energy efficiency and long life of low-voltage LED lighting is critical, said the company. Similarly, the Dimmer's small size benefits machine builders who need to implement LED lighting as part of their product.

The dimmer includes a built-in test pushbutton for ramping LED intensity up and down, connectors for wiring a pushbutton for manual operation, and indicator lights to show serial communication and ramping operation.

The Network LED Dimmer, Opto 22 part number LED-SPCV-LV100W, is available at a list price of $79.00.
