The LDU provides individual dimming control for four 28VDC LED lamps. It provides four 28VDC high-current PWM channels.
Each output channel is designed for a load of up to 1A @ 28VDC. The PWM frequency for all four channels is software configurable in the range of 30 up to 400 Hz.
The LDU is connected to CMS controllers via aTIA-485 bus interface.
