Power supply unit type MNG 2,5-230/24 and MNG 5-230/24
generating a supply voltage of 24 VDC from mains 230 VAC
1.
General information
The power supply units type MNG generate a supply voltage of 24
VDC from mains 230 VAC for solenoid actuated hydraulic valves or
electronic amplifiers connected to proportional solenoids. A safety
transformer conforming EN 60 742 (DIN VDE 0551) supplies a
smoothed DC voltage with either max. 2,5 or 5 A. The load curve (I-U)
conforms the standard DIN 19 240.
The power supply units feature
- CE approval
- UL and CSA approval
- SEE (Luxembourg) approval
- Protection against electric shock conforming VBG 4
- Fulfill the German Standard DIN VDE 0106 T 101 (save separation)

Notes for installation
The power supply unit should be safeguarded against short-cuts on the primary side (recom. Fuse, see 2.2.2.). This safeguard must
be certified as well for all applications, where UL or CSA standards do apply. The GND-terminal of the secondary coil may be
connected to the protective terminal acc. to DIN VDE 0113 and DIN EN 60204. Observe information on installed position and max. in
sect. 2.2.1 !
