Name: The the upscale imported IC dimming Lightning source 7 * 1W 【Model】: HCFDZ-40701 [Input Voltage]: AC85-265V [Output voltage: DC/21-28V (lamp beads parameters automatically adjust the voltage) [ output current] :270-300MA 【quantities adjustable current】 【Output Power: 7 1W lamp beads even [Dimensions]: 42 * 20 * 18MM [efficiency]: ≥ 80% [Power Factor]: ≥ 0.65 [Frequency: 50/60Hz 【protection function: over-voltage, overload, short-circuit protection. [Special note: The group of the two white lines as an input, a red one white group output, red LED lights to Pearl cathode white LED lamp beads to negative. Features:. Adopt the original IC, in line with the global standard. Stable and reliable quality, stable performance. Two. Has a perfect over-current, over-voltage, overload, over-temperature, short-circuit, open circuit protection (automatic recovery). . Constant high precision output current DC ripple of job-hopping, low-temperature, long service life. Wide input voltage, high conversion efficiency. The high-precision constant output current, low noise, (according to the design of the LED characteristics) LED lamps use safer, more stable. Long life design, high reliability, 100% load aging and fully functional test. 7. Drive a variety of colors high power LED
