5. Operating method
1. Setting the constant voltage output:
Turn the current regulator (4) clockwise until it stops. Turn on the machine's power switch
(8) and turn the voltage regulator (3) to the desired output voltage.
2. Current limitation / constant current output:
Disconnect a possible connected load from the output sockets. Turn on the power switch
(8) and adjust the voltage regulator (3) clockwise to the desired output voltage. Turn the
current regulator (4) counter-clockwise until it stops.
Short the output sockets (5 + 7) of the power supply by means of a shorting bridge and then
turn the current regulator (4) clockwise to set the desired output current respectively the
desired current limit.
Note:
The maximum output current is determined by the connected load. You can
’t charge a
connected consumer with a higher power than it actually needs. To achieve the full 5A,
short the output sockets for adjusting the current limitation.
6. Caution !
1.
If the power supply cannot be turned on and the mains supply is turned on, the fuse of the
laboratory power supply maybe triggered. Turn on the laboratory power supply, unplug the
power cord and replace the fuse.
Does the replacement of the fuse is not successful, maybe a defective in the device can be
present.
Consult your dealer to carry out an inspection.
2.
If the output voltage in constant voltage mode is lower than the preset voltage and the CC
indicator lights, the power supply has automatically switched to the constant current mode.
Check the connected load or increase the output current.
3.
If the output current in constant current mode is lower than the preset current and the CV
indicator lights, the power supply has automatically switched to the constant voltage mode.
Check the connected load or increase the output voltage.
4. If the output voltage in constant voltage operation is not stable or jumps, it is probably the
mains supply voltage drops below 90% of the rated value. If the problem is not caused by the
mains supply voltage, contact your dealer.
7. Caution !
In the event of a short circuit at the output the current will limit at the value set by the current
controls, however the unit should be turned off and the short circuit removed before continuing use.
The mains power must be switched off before servicing and servicing should be referred to a
qualified person. The unit should be stored in a dry and well ventilated place and the power cord
removed if storing for long periods.
Laboratory Power Supplies are not designed for charging batteries. Any use of this type can cause
serious damage to the device, which are exempt from any legal claims whatever.
