Setting the output voltage of output A and C
• 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.
• Use the “VOLT” rotary control (4 or 15) to set the output voltage.
• The voltage value “V” is indicated on the display (3 or 21)
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 of output A or C
Limiting the output current is a protective mechanism to protect the consumer or connecting cables. Current limitation
can be preset without short-circuit at the output. The power supply supplies the maximum preset current.
• 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 output A (36 and 37) or output C (28 and 29) and switch it on. Pay attention to the polarity.
The “CC” LED display (7 or 18) lights up as soon as the set current level is exceeded and current limitation is active.
Constant current mode is active.
If the preset current strength is reached in normal mode, the power supply switches to current limitation
mode and reduces the voltage value. This operation is indicated with a red “CC” status display (7 or 18).
Setting the overvoltage protection (OVP) and resetting the device
Outputs A and C have adjustable overvoltage protection. This protective mechanism prevents the accidental destruc-
tion of connected consumers due to an excessively high output voltage. Upon reaching the preset safety level, the
respective output (A or C) is switched off immediately. The USB outputs are not affected.
To set the safety level, proceed as follows:
