Device balancing
1.
Power supply unit 1 is in operation and at no-load mode. The desired output voltage
is set via the potentiometer using a voltmeter (see Figure 3-1).

2.
Both power supply units and the voltmeter are connected as shown in Figure 3-2. Both
power supply units are in operation and at no-load mode. Balancing of the power
supply units is carried out by means of differential voltage measurement. For this, the
output voltage of power supply unit 2 is adjusted using the potentiometer until the
voltmeter no longer measures any voltage. Both output voltages are exactly set if the
differential voltage between both power supply units is 0 V. The lower the differential
voltage of the power supply units 1 and 2 the more symmetrical the distribution of the
total current for the two single units.
