5.4.7. Output B USB-B2
Output B USB-B2 is processor-controlled and is not adjustable. This output identifies the parameters of the connected
terminal device and automatically sets the best possible settings for voltage and current.
Display of the current parameters is not possible.
5.5. Connecting a consumer
When connecting a consumer, ensure that it is connected to the power supply when switched off.
The maximum current consumption of the device to be connected must not exceed the capacity
indicated in the technical specifications.
When switching the outputs of several power supplies in series, voltages of >70 V/DC may be
generated, which may be fatal if touched. Above of this voltage, you may only use insulated
accessories (connection/measuring lines, etc.)
Avoid the use of non-insulated metallic cables and contacts. All of these bare spots must be
covered with suitable, flame-resistant insulation materials or by means other measures to prevent
direct contact and short-circuits.
Ensure a sufficient cable diameter for the intended current strength.
• Disconnect consumers connected to outputs A, B1 and B2.
• Switch the power supply on at the power switch (1). The operating display (24) lights up and the current and voltage
display appear on the display.
•
Set the parameters for outputs A and USB-B1 according to your specifications as outlined in the chapter “Opera
-
tion”.
• Verify again that the output voltage has been set correctly.
• At output A, connect the positive terminal (+) of the consumer to the red socket “+” and the negative terminal to
the blue socket “-”.
• At output B, connect the USB plug of the consumer to the USB socket.
• Now you can switch the connected consumer on.
