Nar­row space for power sup­plies

DEMM Engineering & Manufacturing - - ELECTRICAL TECHNOLOGY -

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.
