Low Profile Single Phase Power Supplies

The Low Profile Single Phase Power Supplies are 15W to 100W single output Class II DIN rail switching power
supplies. They are designed for the fast growing demand of the DIN rail application with limited enclosure
height. With Class II of protection level, low profile 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. Complying with the safety of the UL508 and EMC requirements of EN50178 which is mainly for
power distribution aspects, the low profile switching power supplies are suitable to be installed in a power
distribution box or a control cabinet and the major application fields are building automation and household
appliance control.
