GlacialPower - New GP-CVP040N Series LED Constant Voltage Driver with TRIAC Dimming

GlacialPower, the power division of the LED technology manufacturer GlacialTech Inc, announces the new GP-CVP040N series LED constant voltage driver. It is available in 12 V DC and 24 V DC output rated power of 40.8 W. The driver supports TRIAC dimming function, and appropriates for LED strips application in places such as restaurants, jewelry shop, home and theater.

•    AC input range from 205 to 256 V AC
•    Constant voltage mode
•    Work with leading edge and trailing edge TRIAC dimmers
•    AC phase-cut dimming
•    IP67 rated
•    Safety protections include OVP, OCP, SCP, and OTP
•    Appropriate for LED strips application
•    2 Years warranty
•    RoHS compliant

The dimming adjustment output of the GP-CVP040N series LED driver ranges from 5% to 100%. Works with leading edge and trailing edge TRIAC dimmers. The typical power conversion efficiency is 82% for 12 V and 84% for 24 V. It supports an AC input voltage range from 205 to 256 VAC.
