Power Electronics / Power Management
The single-output, enclosed AC-DC power supplies in Mean Well’s LRS-200 (200 Watt) and LRS-350 (350 Watt) series are housed in compact cases just 30 mm high, and have no-load power consumption below 0,75 W.
Inputs in the 90 – 132 V a.c. and 180 – 264 V a.c. ranges are supported (selectable by switch) and the units can withstand 300 V a.c. surge input for 5 seconds. The LRS-200 is cooled by free air convection, whereas the LRS-350 exploits a built-in fan for forced air cooling. With operating efficiency up to 90%, both models can be operated across -30°C to +70°C.
The power supplies can withstand 5 G vibrations and are equipped with a power-on LED indicator. They comply with the UL 60950-1 safety regulation, complete with protection functions such as short circuit, overload, over-voltage and over-temperature.
The units are suitable for industrial automation equipment and control systems, electromechanical appliances, electronic instruments, etc.
