LED lighting dimming function is controlled through AC power switch

June 19, 2013 // By Christoph Hammerschmidt
GlacialPower has announced six new constant current and constant voltage step-dimming GP-LP060P LED drivers. The rivers cover the entire DC output range of 12V to 57V DC and deliver up to 60W of power to the LED.

The six products differ in that they provide different voltages at the output; they feature voltage ranges between 8 to 12V and 48 to 57V. The step dimming function for constant current and constant voltage can be controlled through the AC power switch. There are four different dimming levels, which can be controlled by switching the light on and off within one second. When the power is switched on the light will have full luminosity, when it is turned off and on again for the first time the luminosity will reduce to 70%, the second time to 45%, and the third time to 15%.

The drivers have a power conversion efficiency rate of up to 86%. The AC input range of the drivers ranges from 90 to 305V AC and the DC input range of the drivers ranges from 127V to 430V DC, making the drivers an option for practically all usage environments.

The drivers have an IP67 approved fully isolated casing as well as four different protections: Over-Temperature Protection (OTP), Over Current Protection (OCP), Short-Circuit Protection (SCP) and Over Voltage Protection (OVP).
