9. Mains socket to connect the enclosed mains cable
10. On/off switch

COMMISSIONING AND OPERATION

a)Connection and operation
• Place the lab mains unit on a firm and level surface.
• First switch off the lab mains unit (put the on/off switch (10) in the “O” position).
• If a consumer is connected to the DC output sockets (4, 8), disconnect it.
• Connect the mains socket (9) to a mains outlet with a protective ground via the included mains cable.
• First switch on the lab mains unit (put the on/off switch (10) in the “I” position).
• The display now shows the currently set output voltage and the value for current limitation. At the DC output sockets (4, 8), the output voltage will only be available when you briefly push the button “OUTPUT ON” so that the button lights up green.

b)Selection of the voltage/current range

The lab mains unit has three voltage/current ranges that you can choose via three buttons:

• “16V/5A” button (3)
  • The lab mains unit delivers an output voltage of 0 – 16 V/DC and a current of 0 – 5 A (max.).
• “27V/3A” button (7)
  • The lab mains unit delivers an output voltage of 0 – 27 V/DC and a current of 0 – 3 A (max.).
• “36V/2.2A” button (6)
  • The lab mains unit delivers an output voltage of 0 – 36 V/DC and a current of 0 – 2.2 A (max.). After pushing the respective button, it lights up. The display shows the currently set output voltage and the value for current limitation.
  • The last value set remains saved after the lab mains unit is switched off.
  • The setting of the respective output voltage and the current limitation is described in the next section.

Observe:

If the DC output is activated (green LED in the button “OUTPUT ON” (2) is lit) and you push one of the three buttons, the DC output is deactivated for reasons of safety (green LED goes out).

c)Setting the output voltage and current limitation

• To set the output voltage and the current limitation, keep one of the buttons “16V/5A” (3), “27V/3A” (7) or “36V/2.2A” (6) pushed (approx. 3 seconds) until the button is flashed.

Observe:

If the DC output is activated (green LED in the button “OUTPUT ON” (2) is lit) and you push one of the three buttons, the DC output is deactivated for reasons of safety (green LED goes out).

• Change the output voltage by turning the dial encoder “VOLT.” (1) to the left or right. If the dial switch is turned slowly, the voltage value changes in small steps. When turning fast, the adjustment is made in large steps.
• Change the value for the current limitation by turning the dial encoder “CURR.” (5) to the left or right. If the dial switch is turned slowly, the current value changes in small steps. When turning fast, the adjustment is made in large steps.
• Save the setting by pushing the lit button “16V/5A” (3), “27V/3A” (7) or “36V/2.2A” (6) briefly. The buttton then stops flashing and the setting mode is completed. If a button that is not lit is pushed (for another voltage/current range,  its setting can be changed as well without leaving the setting mode.

d)Activate/deactivate output

Before activating the DC output, always check if the operating voltage of the consumer connected to the lab mains unit matches the output voltage of the lab mains unit. Otherwise, the consumer will be damaged; there also is a danger of fire and explosion (depending on the consumer)! As a special feature of the lab mains unit, the DC output can be activated/deactivated by pushing the button “OUTPUT ON” (2).

A green LED in the button displays the condition of the output:

• LED is lit: The output is activated and delivers voltage/current
• LED is not lit: The output is deactivated This way, it is not necessary to disconnect the consumer from the lab mains unit if you want to make changes, e.g., to the consumer circuit, or similar.

e)LEDs “C.V.” and “C.C.”

The two LEDs show whether the output currently provides a constant voltage or a constant current.

• LED “C.V.”: Output delivers constant voltage (“C.V.” = “Constant Voltage”).
• LED “C.C.”: Output delivers constant current (“C.C.” = “Constant Current”).
  • If the LED “C.C.” is lit, the set current limitation of the lab mains unit is active

f)Connecting consumers

First, ensure that the total power of all consumers connected to the lab mains unit together does not exceed the maximum output of the lab mains unit.

The consumers should always be switched off when they are connected to the lab mains unit. Otherwise, sparks may result that will damage the output sockets of the lab mains unit as well as the plugs used by you.

• If this has not been done yet, connect the lab mains unit and switch it on (see chapter 7. a).
• Provide the required operating voltage for the respective consumers; see chapters 7. b) and 7. c). The same applies to the current limitation. If no current limitation is to be used, set the current value to maximum.
• Deactivate the DC output; push the button “OUTPUT ON” (2), so that the green LED in the button is not lit.
• Connect the negative connection (-) of the consumer to the DC output socket “-” (4) of the lab mains unit.
• Then connect the positive connection (+) of the consumer to the DC output socket “+” (8) of the lab mains unit.
• Use sufficiently sized cables (depending on the output current).
• The lab mains unit has 4 mm safety sockets so corresponding 4 mm-banana plugs are required.
• Check again that the output voltage shown in the display of the lab mains unit corresponds to the operating voltage of the consumers.
• Then push the button “OUTPUT ON” (2) to activate the DC output; the green LED in the button lights up.
• The current values for current and voltage appear in the display.
• On-demand, you can also adjust the value for the current limitation or the value for the current control with the output sockets released.
• To deactivate the DC output; push the button “OUTPUT ON” (2), so that the LED in the button goes out.

CLEANING AND MAINTENANCE

The lab mains unit is maintenance-free for you apart from occasional cleaning and fuse change; never disassemble it. Opening of the lab mains unit, maintenance and repairs must only be done by a specialist.

Cleaning

• Always switch off the lab mains unit before cleaning and disconnect it from the mains voltage (pull the mains plug).
• Clean the product only with a dry, soft, clean cloth. Dust can be removed easily with a dry, clean brush and a vacuum cleaner.
• Do not use any aggressive cleaning agents for cleaning, or even chemicals; this may cause not only discolouration but also damage to the product.

FUNCTIONAL PROBLEMS

The lab mains unit does not work, the displays are not lit:

• Check the on/off switch (switch position “I” = on).
• Check that the mains cable is firmly connected to the lab mains unit and whether it is plugged into a proper mains socket with protective contact (wall outlet).
• Check the functionality of the mains socket (e.g. fuse, circuit breaker, fault interrupter protection switch).

The connected consumers do not work:

• Check polarity at the DC output sockets (4, 8).
• Check that the current limitation is activated; if required, set a higher value for the current limitation (or set the maximum value).
• Observe that the lab mains unit has three different voltage/current ranges that can be selected via the three buttons “16V/5A” (3), “27V/3A” (7) or “36V/2.2A” (6); see chapter 7. b).
• When the consumer needs, for instance, an operating voltage of 30 V/DC, select the corresponding range with the button “36V/2.2A”. Only an output current up to 2.2 A is available here, however.
• Reduce the load of the lab mains unit.
• Check the technical data of the consumers (operating voltage, current consumption, voltage type).
