Description
The EK-PSUDxx device is a switching power supply with 100 to 240 Vac and 50
to 60 Hz input, or 110 to 350 Vdc input, capable of delivering an adjustable output
voltage of 23.3 to 28 Vdc. Suitable for installation in electrical panels on a 35 mm
profile rail (according to EN 60715), it is also equipped with thermal, overload and
short-circuit protection and supplied in a UL94V-0 fire-resistant plastic case with 2
modular units (1 UM = 18 mm).
Connections
• Screw terminals for mains input
• Screw terminals for load outputs
• Screw terminals for output voltage adjustment
Main features
• Output voltage adjustment in the range 23.3 ÷ 28 Vdc
using an adjustable trimmer with Phillips screwdriver.
• Particularly suitable for powering Delégo EK-DEL-... modules designed for the
supervision and control of KNX standard home automation systems.
