Green Watt Power, a division of Calex Mfg. Co., Inc. announces the introduction of the GLCD 50 Watt constant current dimmable LED power supplies. The dimming options for the GLCD 50 include 0-10V, PWM and external potentiometer. All models feature a universal 100- 277VAC input with nominal output current values of 500mA, 700mA, 1.05A, 1.4A, 1.75A, 2.1A and 2.8A. The dimming range is 10 to 100%. Contact the factory for 0 to 100% dimming options. 

All models are RoHS compliant, IP67 rated and backed by Green Watt Power’s Five Year Warranty. The power factor correction for all models is 0.95 and total harmonic noise is less than 20%. Rise time is 200ms and setup time is 2s. Overshoot and undershoot response is +/-10%. Ripple and noise is 5% of I out. Input to output withstand voltage is 3750 VAC. The MTBF per MIL-HDBK-217F is 200k hours. The operating temperature of the GLCD 50 is -35 to 70C ambient. All models are protected by over voltage protection, short circuit protection and over temperature protection/shutdown with auto-recovery. The case size of the GLCD 50 is 5.98” x 1.73” x 1.25”H.
