Mean Well announced HSP-250 series, 125~250W AC/DC power supplies for LED display applications

Mean Well » HSP-250


With the booming of green energy concerns, high efficiency power supply requirement became more and more popular for LED moving sign manufacturers. MEAN WELL announced the availability of its HSP-250 series, 125~250W AC/DC high efficiency enclosed type power supplies for LED display applications. HSP-250 features with active PFC function and provides three low output voltage models (2.5V/3.6V/5V, 50A), which are designed to drive the RGB (red, green and blue colors) LED chips. Compare to the traditional driving method that use only one 5V voltage power supply to drive RGB LEDs by further dragging down to different voltages, this new system design concept can greatly increase the overall efficiency by using lower driving voltages (ex. 2.5V, 3.6V) directly and achieve the energy-saving purpose.

Mean Well - HSP-250

HSP-250 is implemented the innovative circuit design of LLC topology which makes the efficiency up to 87% even for low output voltage models. With built-in long life DC fan, it can be operated from –40 °C to +50 °C ambient temperature under full load condition and even up to +70 °C by suitable derating that meet all kinds of LED sign board assembly requirements. Furthermore, in order to fit in with the humid and dusty environment for LED display installation, all series equipped with basic anti-moisture and anti-dust ability by the conformal coating protection on the PCB. To solve the voltage drop problem caused by output wiring, HSP-250 is built-in remote sense function to compensate the voltage drop. Other standard functions include: cooling fan ON/OFF control, short circuit, overload, over voltage and over temperature protections. In addition, all series comply with UL, CUL, TUV, CB and CE that can greatly guarantee your safety. Applications include LED electric display, LED TV wall and LED moving sign… etc.
