Velleman PS3003 - Manual (Page 4)

PS3003 HQPOWER 4
3) Using the device as a C.C. source
Use the power switch (9) to activate the device. Turn adjustments (5) and (6) to the extreme right and turn
adjustments (3) and (4) to the extreme left. Connect the load. Adjust (3) and (4) until the desired current is obtained.
The C.C. indicator is now lit while the C.V. indicator is off.
4) Use of the current-limiting adjustment in the C.V. mode
Place both of the current adjustments, viz. (3) and (4), in the max. position. You can now set the current-limiting point
arbitrarily (max. ± 3.5A). Proceed as follows: activate the device, connect a variable load and adjust the load so that
the current matches the desired current-limiting point. Meanwhile, you should also manipulate current-adjustments
(3) and (4) until the C.C. LED lights. The value on the Amp display is identical to the current-limiting point.
4. Safety Prescriptions
- The
PS3003 enjoys optimal protection thanks to the short-circuit protection and the current-limiting point.
However, the power loss of the power transistors is maximal in case of a short circuit. Consequently, the device
should be switched off in order to protect it from damage.
- Store the device in a dry and well-ventilated environment and wipe it clean regularly with a damp cloth. Remove
the power plug if the device is to be stored for a prolonged period of time.
- Cut off the input voltage prior to cleaning the device.
- 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.
- Improper operation of the device and an excessive ambient temperature may cause certain internal components
to fail. When this happens, the actual output voltage may exceed the rated output voltage. PROCEED WITH
CAUTION WHEN USING THIS DEVICE AND AVOID UNNECESSARY DAMAGE TO THE LOAD.
- The 3-pins ground terminal of the power cord should be grounded securely in order to ensure safe operation of
the device.
