For troubleshooting USB ports and USB chargers
Tests the power delivery capability of USB ports up to 100Watts according to USB Battery Charging 1.2 and USB Power Delivery standards.
Tests the power delivery capability of USB chargers (Detects proprietary chargers and adjusts the maximum current accordingly).
Negotiates voltage levels with host PD controller chip to switch between different voltage levels. Dissipates 50 watts continuously, and up to 100 watts for short periods.
Current can be adjusted with milliamp precision using rotary encoder or via software.
Measure electrical ripple at 1kHz.
Measure the capacity of USB power banks and battery packs in mAh.
Test communication speed, data integrity, and power delivery of USB ports simultaneously.
Built-in protection against overcurrent, over voltage, over temperature and ESD.
Isolated USB Monitoring port which protects the monitoring machine.
Controllable and configurable over USB interface. The API which allows you to change the load, read the current and voltage levels and Update the LCD contents.
Bootloader which allows updating the firmware in field.
Python Script example is now included.
USB-PD (‘PD’ stands for ‘Power Delivery’) is a universal standard that can fast-charge a variety of devices that use USB-C to deliver increased power (more than 7.5 W) to devices with greater power demands. Devices can request higher currents and supply voltages from compliant USB-PD hosts, for example a phone may request 15W of power, where a laptop might request 45W.
Quick Charge is a proprietary charging protocol developed by Qualcomm, which is used to manage power delivered to a range of devices by USB. It achieves this by having these devices communicate with the power supply and negotiate an appropriate and increased voltage, which results in faster charging. Quick Charge 4+ is the latest version of this technology and can support between 3V-21V at 100W (20v/5A).
Programmable Power Supply (PPS) capability allows for incremental changes in voltage and current. PPS allows the adapter to have a variable output voltage by communicating with the device being charged, optimising charging conditions relative to each device.
An E-Marked cable (electronically marked cable) is a USB Type-C cable that uses a marker chip to provide the cable’s characteristics e.g. its current carrying capability, its performance, vendor identification, etc. E-Marked chips are required when:
