DIP Switch Current Selection

The DIP switches allow quick selection of 8 different current output levels for each model. Before setting the current via DIP switches, ensure the LED driver is powered off. Powering the driver on again makes the current setting effective. Note: Failure to power off the driver before setting the current may damage the light fixture.

The table shows output current (100mA to 400mA), output voltage (9-42V for most, 9-40V for 300mA), and output power (0.9W-12W) corresponding to different DIP switch combinations.

Flicker Test Sheet

The Flicker Test Sheet details the limits of modulation for different risk areas according to IEEE 1789 standards. It includes tables for modulation limits in low-risk and no-effect areas based on waveform frequency. The Modulation Area Diagram visually represents these risk zones (IEEE 1789 Low Risk, IEEE 1789 High Risk, IEEE 1789 No Effect) against frequency and modulation percentage. The output frequency is 0Hz at 100% brightness, with 0% modulation, which is not depicted on the main diagram.
