Feature: 1. LED dimmable power supply possess slim type design so as to install easier. 2. Dimming options have triac(front edge dimming with adjustable AC range 50V~240V) and 0-10V(or 1-10V) dimming mode, automatic compatibility and automatic identification, don't switch by hand. 3. There are anti-surge, anti-lightning and anti-interference protective circle at the input side. At the output side, there are overload, over-current and over-voltage protection. 4. Safe installation transformer is installed between input and output sides. The ground wire connects with outer case to prevent case from electricity. 5. Possess stable output voltage and output current, flicker free. Stable dimming effects, no shaking, sensitive and fluent. Specification: Item Type: LED Dimmable Power Supply Type: LED power supply Modulation Method: Pulse width modulation (PWM) type Transistor Connection Mode: Full bridge Output Power: 150 (W) Work Efficiency: 95 (%) Output Ripple Noise: 85mv Load Adjustment Rate: 5 (%) Working Temperature: -30 degrees to 40 degrees (℃)Suitable for indoor LEDs, lights, light strips, wall washer lights, etc. It can be separately combined with the corresponding dimming control panel (dimmer), lights or light strips to form a minimum dimming system. Each system works and controls independently, which is suitable for manual control and adjustment of lights in hotel rooms and lobbies.. Package List: 1 x LED Dimmable Power Supply Note: 1. Be only applied to Triac (front edge, adjustable voltage range AC 50‑240V) and 0‑10V(or 1‑10V) dimming mode. 2. If you use the trailing edge traic dimming such as the adjustable voltage range AC , there is a very short adjustable range and don't feel any dimming effect. 3. 0‑10V means dimming effect from 0% to 100%, 1‑ 10V means from 10% to 100%, it depends on the dimmer signal, the dimming driver is passive to receive the dimming signal and adjust the output brightness accordingly.4. Please note that the new type and old type of this product will be sent randomly,and make sure you will not mind before ordering.
