Provides independent, constant-current control of two LED loads at up to 4amps continuous DC and a maximum output power of 60 Watts per channel. In Pulse (Strobe) Mode, the ULC-2 is capable of output currents up to 40 amps. The ULC-2 is capable of driving LED forward voltages between 3V and 20V and higher, but with a possible reduction in maximum pulse current. Pulsewidths are adjustable down to 2 microseconds and external trigger rates up to 50kHz.


  • Strobe or Continuous operation
  • 2 Channel Output
  • Din Rail Mountable
  • Compact Design
  • LCD Display
  • Ethernet and USB Connectivity


This unit is a comprehensive control device built for compatibility with standard LED illumination systems.
For continuous, intensity, and strobing control with programmability for preset parameters, trigger delay, and pulse variation via user-friendly LCD or using Ethernet and USB commands.

Wiring Diagram
*Please refer to the diagram below for LED output and trigger input connections.

The ULC-2 shall be powered by a user-supplied power supply having the following ratings:

  • 24VDC
  • 6A
  • Switching power supply preferred
  • To minimize rise-time distortion and guarantee pulsewidth values, keep all LED load wires as short as possible.

ULC-2 Trigger Inputs

  • For external trigger operation, each channel provides separate trigger inputs. Trigger pulses enable the LED output for a period set by the Pulsewidth parameter.

ULC-2 LED Outputs

  • With the ULC-2 un-powered, connect channel 1 & 2 LED loads to the positive and negative LED outputs.
