3.2 Rear side, Connections
Figure:
Rear side of a MCA 750
– 1500 unit. The dimensions of units with higher power and/or
other voltages are different to this type. In this case the arrangement of the elements
can be different as shown above.
1.
Mains power input, built in fuses
up to 700W: Mains plug as shown above.
1400W and higher:
Tightly with automatic cutout and cable connection or mainsplug C20 (IEC60320).
2.
earth stud. (only with high leakage current)
3.
mounting place for optional analog programming
4.
mounting place for optional interface Probus V (i.e. IEEE-488, RS232, USB, LAN)
5.
Positive high voltage output socket
6.
Negative 0V connector (internally connected to earth, connection can be removed if necessary)
7.
earth stud.
3.3 Assembly
The power supply consists basically of 4 main units
Mains source and oscillating unit
HV-transformer, HV-rectifier with filter, HV-divider and current measuring shunt
Control unit with measuring and control amplifier, reference voltage source,
pulse width modulator, source for the control unit from the mains transformer
and
a ±15 V voltage stabilizer.
Front panel board with 7-segment display, microcontroller, digital calibration
