General Guidelines
Refer to the
Velleman® Service and Quality Warranty
on the last pages of this manual.
x
Familiarise yourself with the functions of the device before actually using it.
x
All modifications of the device are forbidden for safety reasons. Damage caused by user modifications to
the device is not covered by the warranty.
x
Only use the device for its intended purpose. Using the device in an unauthorised way will void the
warranty.
x
Damage caused by disregard of certain guidelines in this manual is not covered by the warranty and the
dealer will not accept responsibility for any ensuing defects or problems.
x
Keep this manual for future reference.
x
The device enjoys optimal protection thanks to the short-circuit protection and the current-limiting point.
The power loss in case of short circuit is limited thanks to the protection circuit that controls the power loss
of the transistors in the power supply. This feature keeps the device from being damaged. The device will
automatically go into the current-limiting mode, which means that the current-limiting point (max. ± 12 A)
is installed. Nevertheless, the short circuit should be repaired as soon as possible in order to prevent wear
and unnecessary power consumption.
x
The output will be cut off if the short-circuit occurs between the positive and the negative output terminal,
which prevents power loss. The device will resume normal operation when the problem has been solved.
x
This device is a large power source. The device should be well-ventilated when working at max. power in
order to avoid overheating. Keep in mind that the surface of the heat sink is too hot to touch when the
device is being used at max. power.
