• Use the “VOLT” rotary control (4 or 15) to set the output voltage. Note that the two set voltages at the output are
added together.
• The voltage values “V” are shown on the display (3 and 21) and must be added together. The sum of the voltage
setting is output at both output sockets (37 and 28).
In normal mode, the device operates in constant voltage mode. This means that the power supply emits a
constant, preset output voltage. This operation is indicated with a green status display “CV” (5 or 16).
Setting the current limitation
• Disconnect consumers connected to output A (36 and 37) and output C (28 and 29). Before setting the current
limitation, always set the correct output voltage.
• Turn the “AMPERE” rotary control (8 or 19) fully to the left (neutral position).
• Press and hold the “C-LIMIT” button (30 or 38) during setting. The respective output is switched off automatically
when the “C-LIMIT” button is pressed. The voltage display then returns to approx. 0.
• The max. current strength (current limitation) can be set with the “AMPERE” rotary control (8 or 19). After complet-
ing setting, release the “C-LIMIT” button. The display shows the actual current strength again (with output 0.00 A
unloaded). The “CV” status display (5 or 16) lights up.
• Connect the consumer to the output sockets “+” of output A (37) and “-” of output C (28) and switch it on. Pay atten-
tion to the polarity. The output voltages of the two outputs add up and are bundled at an output.
The “CC” LED display (7 or 18) lights up at the respective output as soon as the set current level is ex-
ceeded and current limitation is active. Constant current mode is active.
6.4.7. Tracking mode (TRCK)
In tracking mode, the output voltage of the two laboratory outputs (Output A and C) is controlled via the VOLT-Master
regulator (4) of OUTPUT A. In this mode, the output voltage of the two outputs is always the same. The current limita-
tion is set at the respective output.
Setting the output voltage
• Disconnect consumers connected to output A (36 and 37) and output C (28 and 29).
• Set the current adjuster for the respective output “AMPERE” (8 or 19) to the centre position.
• In this operating mode, the voltage regulator at output C (15) must be set to maximum (right limit stop). This enables
sole control via output A.
