Product Introduction
The 48V 800W switching power supply is an industrial single-output AC-DC power unit. Rated output 48V, 800W, output current approx 16.7A. It accepts 90~264V wide AC input with built-in active PFC, converting mains power into stable 48V DC. Widely applied in telecom cabinets, energy storage systems, industrial automation, robotics, charging auxiliary power, laser equipment, security systems and high-power LED lighting.
Adopting high-frequency switching topology and air cooling design, the standard metal casing supports rack mounting. Units can be paralleled for higher total power, making it a versatile standard power source for 48V DC systems.
Product Advantages & Features
1.High efficiency up to 88%-92%, PFC＞0.95, less power loss and heat generation, saving operation cost and cooling budget.
2.Complete protection: over voltage, over current, short circuit, over temperature, under voltage lockout. Auto-protect loads and recover after fault removal.
3.90–264VAC universal input, works for most global power grids, stable under voltage fluctuation.
4.Good EMC performance, low electromagnetic noise, compliant with CE, FCC, RoHS for overseas market access.
5.Parallel operation support, output voltage trim and remote on/off control available.
6.Wide operating temperature range: -20℃ ~ +60℃, premium capacitors and power components for stable performance in harsh environments.
