Narrow space for power supplies
The Wieland Electric Wipos PB1 power supply series is designed for low installation heights and narrow installation spaces that are common for small distribution boards, shunting distributors and control cabinet applications.
For some buildings, electrical installations are often laid in suspended ceilings, in intermediate f loors or in the trunking, therefore, the switching power supplies are designed for 0.42 to 4.2 A and are mounted on DIN rails with screw connection also possible from 2.5 A upwards.
These compact AC/DC power supply units supply 100 per cent output at ambient temperatures of up to 60°C and can be used in a wide temperature range between -25 and 70°C, as well as in outside areas.
Other features of the power supply series include long hold-up times of > 60 ms, compensation of voltage drops through adjustable output voltage as well as a broad-range voltage input for worldwide use. The LED diagnosis enables easy commissioning.
