Frequently Asked Questions - PS3020 VELLEMAN

How to adjust the output voltage in constant voltage mode?

Turn the coarse C.V. adjustment knob (5) for an approximate voltage, then the fine C.V. adjustment (6) for the exact voltage. The C.V. LED (8) lights up.

How to adjust the output current in constant current mode?

Turn on the device, turn the C.V. controls (5) and (6) fully clockwise, and the C.C. controls (3) and (4) fully counterclockwise. Connect the load, then adjust (3) and (4) until the desired current is reached. The C.C. LED (7) lights up.

How to limit current in constant voltage mode?

Set the current controls (3) and (4) to maximum, then adjust the load so that the current reaches the desired limiting value. Adjust (3) and (4) until the C.C. LED lights up. The displayed current is then the limiting point.

What do the C.C. and C.V. LED indicators mean?

The C.V. LED (8) lights up in constant voltage mode. The C.C. LED (7) lights up in constant current mode or when current limiting is active.

What are the protections of the device?

The device has an adjustable current limit and short-circuit protection. In case of a short circuit, the output is automatically cut off.

How to connect a load?

Connect the positive terminal of the load to the positive output terminal (+) and the negative terminal to the negative terminal (-). Ensure that the case ground is properly connected.

What to do in case of a short circuit?

The device automatically enters current limiting mode. Remedy the short circuit as soon as possible to avoid premature wear.

How to clean and maintain the device?

Disconnect the device before cleaning. Clean with a damp cloth. Store in a dry and ventilated place.

What is the required input voltage?

The device operates on an input voltage of 220V ± 10%, 50Hz ± 2Hz.

What is the warranty period?

Important environmental information about this product

This symbol on the device or the package indicates that disposal of the device after its lifecycle could harm the environment. Do not dispose of the unit (or batteries) as unsorted municipal waste; it should be taken to a specialised company for recycling. This device should be returned to your distributor or to a local recycling

service. Respect the local environmental rules.

If in doubt, contact your local waste disposal authorities.

Thank you for choosing VELLEMAN! The PS3010/PS3020 is a highly accurate, DC-regulated power supply with an adjustable output. This output can be used for constant voltage (C.V.) and constant current (C.C.).

The output voltage can be adjusted between 0V and 30V when the device is in the constant voltage mode or C.V.-mode. The current-limiting point (max. ± 12A) can also be set arbitrarily in this mode.

The output current can be adjusted continuously between 0 and 10A in the constant current mode.

The output current and voltage are indicated through LED displays.

3. Description

3.1. Controls and Description of the Front Panel

(1) Amp-display (LED): indicates the output current.
(2) Volt-display (LED): indicates the output voltage.
(3) C.C. fine-tuning: rotary switch for the fine-tuning of the current-limiting point.
(4) C.C. adjustment: rotary switch for the adjustment of the current-limiting point.

(5) C.V. adjustment: rotary switch for the adjustment of the output voltage.
(6) C.V. fine-tuning: rotary switch for the fine-tuning of the output voltage.
(7) C.C. indicator: the LED is lit when the device is in the C.C.-mode.
(8) C.V. indicator: the LED is lit when the device is in the C.V.-mode.

(9) Power switch: push-button used to activate/deactivate the device. The device is ON when either the C.C. LED (7) or the C.V. LED (8) is lit.

(10) Output terminal (+): used for the connection of the load's positive terminal.

(11) Ground connection of the housing: the housing is grounded.

(12) Output terminal (-): used for the connection of the load's negative terminal.

3.2. Operating Procedure

1) Using the device as a C.V. source

Turn adjustments (3) and (4) to the extreme right prior to activating the device. Activate the device. Use adjustment (5) to obtain a voltage that is close to the desired value. Consequently, you should use fine-tuning adjustment (6) to install the exact value. The C.V. indicator comes on.

2) Connecting the Load

The load is connected as shown in the figure above. You can read the output current (1) and the output voltage (2) from the display as soon as the device has been switched on. The C.V. indicator (8) is lit if the device is in the C.V.-mode. The C.V. LED is off and the C.C. LED will light if the Amp display indicates a value that exceeds the installed value. When this happens, the device will automatically go into the current-limiting mode. Install a load that will allow the device to function normally.

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. ± 12A). 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 PS3010/PS3020 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. ± 12A) is installed.

Nevertheless, the short circuit should be repaired as soon as possible in order to prevent wear and unnecessary power consumption.

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.

• 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.
• The fan kicks in when the temperature of the heat sink reaches ±75^ C.
