Constant current LED Drivers For outdoor use LGU-250C Series, 250 Watt DIMMING FUNCTION Note: 1. To make the driver operate properly, the load voltage must be controlled above the minimum voltage which close to 50% of the maximum output voltage is from any given mode. 2. The dimming signal can be less than 1V. As it is for 0-1V ,the output current can maintain 10% of the rated output current, but the connected LEDs may flicker. It's strongly recommended that keep dimming voltage bigger than 1V. 3. It is not allowed to connect the GND of dimming to the output, or the LED driver can not work as normal. PWM Dimming ITEM Conditions Value Input Voltage -- 1-10V Input Current -- 10mA PWM Frequency -- 0.5-3KHz PWM Pulse Width -- 0~100% Timer Dimming Note: Above table for Timer dimming is just for reference, it can be adjusted according to the customer's requirements. www.pairuigroup.com Page: 5 / 5 Date: 07/18/2015 *Subject to change without prior notice.
