[Text|High-tech LED reporter Long Zonghui] LED streetlights can not meet the market application once, and the intelligent lighting system with integrated functions such as time control and network maintenance alarm is the inevitable development trend in the future.
“Huaweiyuan can launch two series of products, namely EHE series, harmonic <10%, efficiency 93.5%. EPE series programmable series and support 485 communication series.†Hua Weiyuan Field Technical Support Manager Tell the reporter.
Among them, the SLWT201CGA series, which uses programming to adjust the brightness to support five dimming methods, has a good response. The series supports the full voltage range of 110V-277V and is suitable for the global market. The rated output power is 200W, and the power factor can reach 0.99 at 110V. Under the 277VAC test environment, the leakage current is controlled at 0.75mA. The output ripple noise is 10%, the load regulation is ±2%, the lightning protection capability is 6KV/6KV, and the harmonic distortion is <10%.
In use, it is only necessary to change the power output current or the external write time control point through an external program device, and the power supply can change the brightness at the corresponding time. Support analog dimming (0-5V/0-10V), communication dimming, PWM dimming, time-controlled dimming, current fine-tuning. Such a power supply can easily realize the secondary energy saving of the luminaire on the basis of the power saving of the LED itself.
