MEAN WELL has introduced the new DR-100 series – 90~100W single output class II DIN rail switching power supply for the fast growing demand of DIN rail applications. With Class II of protection level (double insulated, no earth ground wire is required), DR-100 series provide users a safer operating environment since the whole plastic case is free from hazardous leakage current. Featuring up to 89% of high efficiency, this series can be cooled by only free air convection that significantly increase the reliability and lifetime of the power supply. To compensate for wiring voltage drops, the output voltage can be adjusted from the front panel, and the colored LED indicator also give an immediate visual conformation of the output status.
One unique feature of “no load power consumption < 1W” has also been incorporated into the DR-100 series. This has great advantage for more and more industrial/commercial applications that have energy-saving concern to differentiate themselves. Complying with the global safety and EMC requirements per UL60950-1, TUV EN60950-1, and EN55022 Class B, these low profile switchers are suitable to be installed in a power distribution box or a control cabinet and hence the major application fields are building automation, security, and household appliance control.
