MEAN WELL High Voltage DC (HVDC)Output: 115/230/380V Power Supply Solutions

High Voltage DC (HVDC)
Output 115/230/380V DC
Power Supply Solutions


As applications of green energy and industrial products become more diversified, related products integrate various high voltage direct current (HVDC) applications directly, such as electrolysis, charging energy storage equipment, UV curing or laser applications to improve product performance and eliminate or reduce unnecessary power conversion losses. More and more industrial products use DC voltages greater than 60V. MEAN WELL has continued to develop a variety of high-voltage output power products, and continues to provide standard power supplies for green energy industries and industrial-grade equipment.

MEAN WELL also provides a variety of cooling methods according to the application requirements of industrial equipment. These include conduction cooling, water cooling and forced air cooling, all designed to offer customers conveniency to accomplish overall planning with system equipment. In addition, the input voltage provide single-phase or three-phase input (AC) voltage, and the output includes three different high-voltage DC, 115V, 230V and 380V, this provides customers with a various selection of high-voltage choices. Moreover, programmable output voltage current and digital communications interface (CANbus/PMBus/MODbus) also helps customer when dealing with system integration or system automation.

Case Studies

With the increase in energy storage and related electric charging applications, in order to shorten the charging time or increase battery capacity, the system will often use multiple battery modules in series to increase the voltage, so as to shorten the charging time and reduce the high current charging, or use parallel connection as a way to increase the capacity of the battery to provide longer use. Therefore, all kinds of high-voltage charging needs can be addressed with MEAN WELL HVDC power supply.

In the early printing industry, UV lamps were used as the ink curing method for printing equipment. However, the development of UV LEDs, which have become widely used in curing applications, has dramatically reduced the overall power consumption of curing lamps and provides longer life (>50,000 hours). In addition, UV LEDs can be used with high-voltage DC power supplies to adjust the brightness (energy) according to the curing distance, which is also a major advantage of LED UV curing.

Compared with traditional lighting, LED lighting can greatly reduce power consumption and radiant heat produced by lamps, and save energy consumption. LED horticultural lighting is more easily configurable, and can provide better and more precise temperature and brightness control for greenhouse cultivation. In addition, in accordance with different plant growth stages, LEDs can be used to adjust the color temperature to provide different wavelengths to help plants grow, increase productivity, and improve economic and environmental benefits. High-voltage DC power supply can be used to reduce the overall cost of lamps and lanterns, while providing different luminaire applications based on a DC centralized bus.
