AC-HV LED series are low-energy consumption with high-performance AC LED drivers.AC-HV LED series is the first
single-chip for high-voltage LED power supply with mass production proved.The creative structure discards the electrolytic capacitors and transformers which are LED lamp life bottleneck. AC-HV LED enables a low cost, small size ,stable performance, long life LED lighting drive. AC-HV LED integrates all the necessary components, driven directly by the AC.
By external resistors ,four LED segment current can be set separately ,which improves LED utilization and THD.AC-HV LED based drive has ideal power supply parameters such as power factor, efficiency, THD,EMI. Which are compatible with different brands of TRIAC dimmers, and support analog 0-10V dimming.This low-cost drive system uses a few components ,for example a 20-watt power supply only needs 10 components.
With external MOSFET, single-chip can control the power up to 50W.Integrated MOS version, Single chip supports 25W.Creative constant lumens control ,can adapt to the input voltage change to maintain a constant input power and output luminous flux.AC-HV LED is more economical than the DC solution in costs and bring a smaller size power systems.AC-HV LED series of product with high efficiency ,high power, low EMI, high reliability ,long life and other advantages ,is ready for mass production.LED lamps based on AC-HV LED series, can pass CE UL CCC etc certification. Please refer to the test report.
