Description:
The DWM-Air9000 is a versatile and reliable handheld power consumption tester designed for precision testing in various applications. It features multiple input options, including connecting to a DC digital power supply or a PD fast charging plug supporting PPS. The device controls the input voltage through the connected power source, ensuring accurate voltage output
Equipped with a wide voltage measurement range of 0-24V and a current measurement range of 0-5A, the DWM-Air9000 offers high precision with measurement errors of less than 0.5% and a maximum resolution of up to 10mV for voltage and 0.15uA for current. Its multiple channels for current synchronous sampling enable efficient and accurate measurements without any shifting delay, with a sampling rate of up to 10KHz, ideal for low power consumption testing.
The DWM-Air9000 can be seamlessly integrated with PC software for real-time monitoring, analysis of current waveforms, and data visualization. This feature makes it suitable for power consumption testing devices such as cellular modules, Bluetooth, Wi-Fi, etc. Additionally, the device supports command-line tools for capturing serial port data on different operating systems (Windows, Linux, Mac), allowing easy data import and analysis using PC software.
Features：
Voltage Output: Depends on the voltage output limit of the charging head and is up to a maximum of 24V
Current Limit: Depends on the current output limit of the charging head and is up to a maximum of 5A
Maximum Power: 120W
Power Supply: USB-C / Power Cord / 0-24V
Hardware Sampling Rate: 80KHz
PC Sampling Rate: 10KHz
PC Software: Windows 7 and above
API Interface: Open dynamic library, that supports all platforms
Special Note: "The power function of DWM-Air9000 needs to be used with a charging head that supports PD function (PPS);
DWM-Air9000 will come with a standard charging head (PD/PPS/65W)."
Maximum measurement range: Voltage up to 24V, accuracy up to 10mV, current up to 5A, accuracy up to 0.15uA.
It uses a 0.4% ±20ppm accuracy reference chip, reserves a 0.1% reference position, 0.1% precision resistor, and a 12-bit ADC design.
Automatic measurement range: Current display ranges are 500μA, 50mA, and 5A, automatically switching based on the current output.
Range switching speed: DWM-Air9000 uses multi-channel synchronous sampling with no shifting delay.
Voltage drop switching speed: DWM-Air9000 uses 2/3 channel sampling resistors, with a maximum delay of 100uS when the sampling resistor is shorted.
Fixed multi-channel 10KHz sampling rate, USB high-speed data transmission.
Current measurement accuracy: Resolution is 0.15μA for the 500μA range and 100μA for the 50mA range, as shown in the table below.
