Setting The Output Voltage And Current Of Output B Usb-B1 - VOLTCRAFT VLP-USB Série Mode D'emploi

Resetting OUTPUT A
As soon as the safety level set with the "VOLT" adjuster (4) has been exceeded, "OUTPUT A" switches off immedi-
ately. The voltage display (3) returns to approx. 0 V and the "OVER VOLTAGE" status display (9) lights up red.
• Disconnect the consumer from the laboratory power supply.
• Turn the "VOLT" adjuster a few turns anti-clockwise.
• Switch the laboratory power supply off and on again with the power switch (1). This resets the protective cut-off.
• Check the correct output voltage again and change the overvoltage protection, if necessary.

5.4.6. Setting the output voltage and current of output B USB-B1

Output B USB-B1 can be used independently of output A. It enables the USB-typical voltage of 5 V/DC
variable from either 4.0 - 5.1 V/DC or 4.0 - 6.2 V/DC for development purposes. The current limitation can
also be preset.
The setting range can be set with the "MODE" push button (10).

"ENG" display (11) flashes.
• Disconnect consumers connected to output USB-B1 (16).
• 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.
• Press and hold the "SHOW VALUE" button (12) while setting the voltage. The display of output A shows the voltage
of output B USB-B1.
The USB symbol (23) lights up and indicates the display of the USB output.
• You can set the output voltage for output B USB-B1 with the "V ADJ." rotary control (13).
• You can adjust the current limitation for output B USB-B1 with the "A ADJ." rotary control (14). Ensure the current
value is high enough to not cutoff the voltage.
• After setting, release the "SHOW VALUE" button (12).
• Connect the consumer to output B USB-B1 (16) and switch it on.Pay attention to the polar-
ity. The USB socket is switched by default. The diagram shows the contacts.
You can check the corresponding voltage and current values at any time by
pressing the "SHOW VALUE" button (12).
