Dimmable 150-W CC LED drivers offer 94% efficiency

The PDA150 series of 150-W constant current LED drivers target commercial lighting applications. Suitable for use in both dry and damp locations, and featuring optional 0 – 10-V dimming, in addition to a 20-V auxiliary output for controllers, the LED drivers provide flicker- and shimmer-free performance in indoor and outdoor fixtures, area, high bay, and architectural lighting.

Rated for input voltages spanning 120 to 277 Vac, the LED drivers deliver 150-W output with typical efficiencies of 94% at 230 to 270 Vac and 92% at 120 Vac. Available with six constant current outputs (350 mA, 530 mA, 700 mA, 1050 mA, 1500 mA, and 1680 mA), the series has a life expectancy of 50,000 hours at full output power, 50°C ambient temperature, and ≤80°C T_case , and 100,000 hours at ≤65°C T_case , with an operating temperature range from –40° to +85°C. Water- and dustproof per IP66, the drivers can tolerate humidity levels ranging from 10 to 95%, and feature over-voltage, over-current, and short-circuit protection that allows them to withstand sustained open circuit and short circuit output conditions without damage.
