In the past few years, we have seen the popularity of USB Type-C port. In the field of power tools, smart home, etc., most of them have been upgraded from the traditional micro port charging mode to the USB Type-C port fast charging mode.
Previously,ChargeLAB has launched many types of testers, detectors, converters and other equipment. This timePD3.1 Deception scheme, launched aPDDecoy board, raise the power cap to140WNext, let's see how it works!
Product Introduction
POWER-Z140WPDDecoy boardThe front components are arranged neatly, and you can see the capacitance, resistanceUSB Type-C female and power socket.
Decoy boardThere are "GND" column, "VBUS" column and a USB Type-C female seat on the left side.
On board intelligent financial SW2505H controller chip, which is an integratedPD3.1、Low power controller chips supported by QC, UFCS and other full protocols have passed USBPD3.1 EPR certification, supporting DRP mode, embedded MCU, 16 GPIO,The C port supports online upgrade, online simulation and debugging, and optocoupler/FB control/I2C supports master-slave mode.
At the same time, there is a modulation button on the right side of the chip, which can switch and set the decoy voltage. The USB Type-C female seat is on the far right.
Decoy boardThe top end has a number of orderly arranged resistors and LED lamp beads at corresponding positions, and screen printed 5V/9V/12V/15V/20V respectively/28VVoltage and PPS1/2/3/4 serial identification.
PD cheat board is placed in the palm of an adult male as above, which is small in size.
Decoy test
This time, you will usePOWER-ZThe P240 tester is used as a load for testing, and is connected to the PD deception board connecting column through the electrode clamp, and adjusted to28V140WDeception voltage, you can see the right side after powering on“28V”The LED bead lights up.
At the same time, use Apple140WThe charger is equipped with 240W wire to connect the power supply inputPOWER-ZKM003C tester detects that the output power of charger terminal is 27.9V 5.02A 139.94W.
Secondly, it can also be seen that the "load meter" display screen shows that the input power at this time is 27.144V 5.000A 135.72W.
Temperature test
Look at the deception28V5A140WHow does the temperature behave.
One hour later, the maximum temperature on the front of the deception version shot with a temperature measuring gun is 36.3 ℃.
The maximum temperature of the back side of the spoof plate photographed with a temperature measuring gun is 34.9 ℃.There is basically no heating when touching by hand, and there is no overheating at the USB-C interface.
Summary of charging head network
Overall,PD deception means that the output voltage and current can be set,POWER-Z140W28VThe PD deception board does not need the tester to replace the resistance and other components by himself. The required 5V/9V/12V/15V/20V/28V voltage gear can be set by adjusting the button, which is easy to operate.At the same time, during PD deception and temperature test, the deception process is transmitted stably, and the measured temperature is only up to 36.3 ℃, without obvious overheating.This is one of the best PD deception devices for testing.
