Power Supply Unit 07 NG 36 R1
primary voltage: 230/400 V 3-phase AC, secondary voltage: 24 V DC, 20 A
The 07 NG 36 power supply unit generates a 24 V DC
voltage from a three-phase mains voltage of 230 V AC or
400 V AC. The output voltage is gained by using a 3-phase bridge-connected rectifier. Together with a filter capacitor, this guarantees a small ripple content of the voltage.
The power supply unit has a load capability of 20 A. It is
suitable for applications in electronic control systems.
A green LED indicates that the output voltage is present.
The electrical connections are made via screw-type terminals. With 3-phase mains voltage of 230 V, the primary
windings of the transformer are delta-connected, with
3-phase mains voltage of 400 V, the windings are starconnected (see Fig. 11.4-1). Cable grips fasten the cables. There is an electrical isolation between the primary
and the secondary voltage according to VDE 0551 (safety
electrical isolation).
The secondary voltage is protected by a built-in B-type
automatic circuit-breaker. The primary voltage (mains) has
to be protected by external fuses.
The power supply is fastened by 4 screws M6 (see Fig.
11.4-2, Drilling pattern).
The power supply unit must be mounted so that the convection air current is not disturbed.
