Hangte LPH200D 3.8V/2.8V 200W common cathode powersupply

Hangte LPH200D3.8+2.8U8 is a 200W fan-less common-cathode LED display power supply. Rather than running every LED colour from a single 5V rail, it delivers two separately regulated outputs — VGB at 3.88-4.1Vdc for the green and blue dies, and VR at 2.88-3.1Vdc for the red — so each colour is driven close to its own forward voltage. The voltage headroom that a conventional single-rail supply burns off as heat inside the driver ICs is largely removed, which lowers overall display power draw and keeps cabinets running cooler. The ultra-thin 30mm slim case suits a wide range of cabinet depths, and every unit is 100% aging tested.
