Intelligent MDP-L1060 DC Electronic Load Power Supply

1. When real-time voltage jump is lower than 70% of the input voltage Vin, the device will display “OCP completel”, and display the end current value, and stop the test;
2. When the pull-in current is greater than or equal to the safety protection setting current, the device will display “Warning! Over Current!” and stop the test;
3. When pull-in current is greater than the hardware maximum current limit, the device will display “Warning! Over MAX Current!” and stop the test.

 Internal Resistance Test (Internal Resis)

Internal resistance test can be used to test the internal resistance of the OUT. This function will automatically run in CC mode. During the internal resistance test, the device will first measure the voltage value Volt1 of the OUT when it is not under load, and then measure the voltage value Volt2 after the short pull-in time, so as to calculate the internal resistance of the device under test:

Internal resistance=(Volt1- Volt2)/(Curr)
Operation method:

1. Set Safety Protection parameter values of MDP-L 1060, and adjust the setting value to the protection function range;
2.  Connect MDP-L 1060 with MDP-M01 display control module to enter advanced function page (please refer to 6.1 for the method of entering advanced functions);
3. Press “TAB” to select internal resistance test interface (Internal Resis), and modify the discharge current setting value Curr of the OUT through MDP-M01 (as shown in the figure below);
4.  Press “CONFIRM” to confirm and start the test.

Pull-In Threshold Voltage (Load Volt Threshold)

MDP-L 1060 can set the load threshold voltage. After the device starts, when detecting the load input voltage is higher than the threshold voltage, the device starts to pull in the load; when detecting the load input voltage is lower than the threshold voltage, the device will automatically stop pulling. This feature can be used to avoid further damage that could result from continuing to pull the load if the DUT fails to work. This function can also be used as a simple automatic test, first set MDP-L 1060’s pull-in load value (pull-in load voltage must be lower than the DUT’s output voltage) and start pulling. When the DUT is connected to MDP-L 1060 {with voltage input), MDP-L 1060 will automatically starts to pull the load, and when the DUT is disconnected from MDP-L 1060 {with no voltage input). the pulling will be automatically turned off. By this, it realize the simple pull-in test of the DUT and save the button operation on MDP-L 1060 for each test.  The setting range of the load threshold voltage is 0V – 60V {the default value is 0.1V). Please refer to 3.5 for the setting method.

Safety Protections

MDP-L 1060 provides a number of security protection functions to protect the device and the DUT. If the device pops up a security protection warning during use, please pay attention to adjusting the corresponding protection parameters. If User need to adjust to the device’s maximum power for testing, User can first turn on pulling load and gradually adjust the preset value to the maximum power to ensure that the device runs smoothly.  For the setting range of each safety protection function parameter, please refer to 3.5.

 Over-Voltage Protection (OVP)

When the load voltage exceeds the set over-voltage value, the device will activate over-voltage protection. At this time, the device will turn off pulling, the buzzer will beep, the upper and lower indicators flicker, and ‘”OVP” warning will appear on the screen.

 Over-Current Protection (OCP)

In CC, CR and CP modes, when the input current exceeds the set over-current, the device will stop pulling with load, the buzzer will beep, the upper and lower indicators flicker. and “OCP” warning will appear on the screen.

Over-Power Protection (OPP)

In normal operation, when the consuming power exceeds the set over-power value, the device will stop pulling with load, the buzzer will beep, the upper and lower indicators flicker, and •opp” warning will appear on the screen.
Note: In CP mode, the device will only start over power protection when the pull-in power exceeds 160W.

Over-Temperature Protection (OTP)

When the temperature of the internal power component exceeds the system protection temperature, the device will activate over-temperature protection. At this time, the device will automatically stop pulling, the buzzer will beep, the upper and lower indicators flicker, and “OVER TEMP” warning will appear on the screen.

Load Input Reverse Connection Protection (Anti-Reverse)

When the load input polarity is reversed, the device buzzer will beep, the upper and lower indicators flicker, and INPUT REVERSEM warning will appear on the screen.

Firmware Upgrade

1. Visit www.miniware.com.cn to download the applicable electronic load firmware to PC;

2.  Connect MDP-L1060 to PC with a USB TYPE-C data cable, press and hold both SET and RUN/LOCK Button to enter DFU mode, the
   computer will display a removable hard disk named “DFU VXXX*;

3.  Copy the prepared .hex firmware to the root directory of that disk. When the firmware suffix changes from .hex to .ROY, restart the device to complete the firmware upgrade.

recommended to connect a power source to the device if to perform a long time testing.
Can the built-in battery be charged when doing a loading test?| The built-in battery can not be charged with DUT, but should be charged independently.| Please connect a DC SV 2A power input for charging via USB TYPE-C port.

There is an obvious deviation in display voltage.

| When the device consumes a large current, there will be a voltage drop on the connection cable between the OUT and itself.| In order to ensure the test accuracy, please connect the XT30 remote compensation port for voltage compensation.

When MDP-L 1060 displays warnings on the screen as below indicated, its upper and lower indicators will flicker in red light, and the buzzer will beep as warning.
