Mean Well announced two series of 96 W to 100 W single-phase (two-phase) high input voltage, metal case LED power supplies – the HVG-100 and HVGC-100 series. With built-in active PFC functionality and IP65/67 waterproof/dustproof level, the power units have a 180 to 480 V a.c. input range and are suitable to use in general power systems with single-phase 230 V a.c. input or can capture one phase from a 380–600 V a.c. three-phase power system.
The HVG(C)-100 has three options (A/B/D type) with different mechanisms and functionality. With the A type of HVG-100, users can adjust the DC current range from 50% to 100% and output voltage by ±10%. In the A type of HVGC-100, users can adjust DC current range from 60% to 100%. B type models feature a three-in-one dimming function (0–10 V d.c., PWM, resistance) while D type models optionally equip a ‘multiple stage timer dimming’ function that can be customised by request.
Designed for constant voltage plus constant current mode, the HVG-100 series are low-voltage output models (54 V d.c. maximum) while the HVGC-100 are
high-voltage output models (285 V d.c. maximum). Both series’ built-in two-stage power factor correction allows them to meet the harmonic current limitation per EN61000-3-2 Class C (>50% load), and they also manage PF > 0,9 if loading over 50% (>80% load under 440 V a.c.).
The power supplies have 4 kV surge immunity (EN61000-4-5) ability which complies with the requirements of street lighting. Their efficiency of up to 92% means they can be cooled by free air convection from -40°C to +70°C ambient temperature and meet the high ambient temperature requirements for closed systems.
Besides standard protection functions for short circuit, over-voltage, overload and over-temperature, the units comply with global certificates per UL/CUL/FCC for HVG-100 and UL/CUL/TUV/CB/CE for HVGC-100, including UL8750 and EN61347-2-13 of lighting regulations. They are suitable to be used in all kinds of LED indoor/ outdoor lighting applications such as LED street lighting, LED high bay lighting, LED office lighting, LED outdoor electric display, LED decorative lighting etc.
