1. 2，Technical Parameter

4.2 Main Interface

4.2.1 Main interface

The main interface is used to display the main parameters, including: input voltage, output

voltage setting, output constant current setting, real-time voltage output, current output, power

output, output mode, working status, lock status, USB-A mode, preset group information and

device temperature.

The information of the main interface is shown in Figure 4.2.1:

① Read back voltage of input, which is power supply voltage, the unit is V.

② Output voltage setting, 00.00~30.00V, resolution 0.01V, unit V.

③ Output constant current setting, 0.000~5.000A, resolution 0.001A, unit A.

④ Output mode, including OFF mode, constant voltage output mode CV, constant current output

mode CC, in CV mode, the brightness of output LED automatically changes with the voltage,

and CC mode automatically changes with the current.

⑤ USB-A mode, including host mode

5V/1A , which can supply power to 5V devices, such as a USB mouse; in slave mode, it is

used for communication with the PC and firmware upgrading.。

⑥ Working state, including seven kinds: normal state NM, overvoltage protection OVP,

overcurrent protection OCP, overpower protection OPP, overheat protection OTP, reverse

connection protection

When it detects other states than the normal state, the device automatically turns off the output

and alarms with a buzzer, and it is forbidden to turn on the output in the UVP state.

⑦ The preset output group currently used, the device supports 10 preset groups (0~9), P[0]

represents preset group 0, each preset group includes output voltage setting, output constant

current setting, overvoltage protection setting, overcurrent protection setting.

⑧ Panel lock state, gray means not locked, it turns orange after locking and operation is invalid,

it is automatically locked after connecting to the PC, and can't be unlocked through panel.

⑨ Device temperature, unit: Celsius (°C).

⑩ Device output power, real-time display of the power value of the device, unit: watt (W).

⑪ Device output current, real-time display the output current value, unit: ampere (A).

⑫ Device output voltage, real-time display the output voltage value, unit: Volt (V).

Note: ① When disconnecting the PC, you can lock and unlock by long pressing the middle button ■; after

connecting to the PC, the middle button is invalid and cannot be unlocked through the control panel.

② When communicating with the PC or upgrading the firmware, please set the USB-A interface to slave

mode(USBD) first, then use the A-A USB cable to connect PC and DP100.
