5. Note
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 !
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.
Do not operate the device to power inductive loads, such as electric motors, which act as generator
during overrun and thus can produce a reverse voltage.
Replace fuse only with an identical fuse.
