Features: components, high reliability. Built-in WMI filter, anti-jamming performance. DC ripple is small, high efficiency. Design soft-start circuit, AC surge current limit. Low operating temperature and long service life. Wide input voltage range, in line with global standards. Insulation performance, high electrical strength. With short circuit, overload, overvoltage, protection. Specifications: Shell Material: Metal case / Aluminum base Protection: Shortage Protection, Overload Protection, Over Voltage Protection Widely used in Industrial automation, LED display, communications, etc. Safety Compliance: CCC/ FCC / CE Size:198x98x42mm Input Voltage: AC110V or 220V Output Voltage: DC5V,20A Rated power:100W Working Temperature: -10~50℃ Note 1) metal shell power line and the shell is generally connected with the ground (FG), to a reliable grounding to ensure safety, not mistakenly connected to the shell on the zero line. 2) Before commissioning, please check and verify the wiring on the terminals again to ensure that the input and output, AC and DC, single-phase and multi-phase, positive and negative voltage and current values, Before running. For high-power power supply, generally have three or more than three "+" input terminals and "-" output terminals, in fact they belong to an output polarity, just for the convenience of users.
