Subject and Type: Power supply devices type PSD1220, type PSD1220-xxx, type PSD1220-098 '-xxx' = non Ex-relevant details of construction and / or function. Description: The power supply devices are designed as stand-alone power supply units comprising of a light alloy enclosure mountable on T35 DIN rails. Each device provides terminals for DC 23.6 – 26.1 V, 20 A output, for AC supply input, fault indicator (power good relay contact) and for load current sharing bus signal in case of paralleled operation. Internal circuitry of directly accessible output voltage adjust-potentiometer complies with level of protection Ex ic IIC. There are no other intrinsically safe circuits. PSD1220 provides plug-in spring connection terminal blocks, PSD1220-098 provides plug-in screw connection terminal blocks. Parameters See Annex Listing of all components used referring to other standards See Annex
The power supply devices shall be installed - in an enclosure corresponding at least to EPL Gc according IEC 60079-0 / IEC 60079-7 and providing degree of IP protection IP54 according to IEC 60529; or - in a controlled environment providing pollution degree 2 according to IEC 60664-1.
