Description
The LE75S-CD Series are constant current mode LED Driver power supplies that operate from a wide range input
of 90 to 305Vac. These models provide up to 2.8A of output current, at a maximum output voltage of 108Vdc, at
up to 75W output power. The LE75S-CD series are highly efficient and highly reliable. Features include dimming
control, overvoltage protection, short circuit protection, and overtemperature protection.

Notes:
1. Efficiency measured at full load, at input voltage noted. Efficiency will be 2% lower if measured immediately after start-up.
2. Measured at 20MHz bandwidth, with noise probe directly across output terminals, and load terminated with 0.1µF ceramic and 10µF low ESR electrolytic
capacitors.
