The following specification is preliminary and subject to change without notice.
The Power Delivery 3.2 specification defines a maximum supported power output of 240W (48V/5A). To meet this testing requirement, the A223808 power module is connected to perform tests for the 240W power specification. Depending on the requirements of the Device Under Test (DUT), the Power Role can be switched accordingly. With both Source and Load functions integrated, users do not need to connect two separate power devices. This setup allows testing whether the DUT can operate normally and meet specifications under various voltage and current conditions.
The A223808 is equipped with a programmable high-precision power supply function. Users can set the voltage range from 3V to 55V, with a minimum adjustable voltage measurement unit of 1 mV/step. This allows precise adjustment of both voltage and current, while enabling simultaneous measurement of voltage (1mV/step) and current (1mA/step).
Chroma A223808 provides OVP (Over Voltage Protection), OCP (Over Current Protection), UVP (Under Voltage Protection), and UCP (Under Current Protection). You can set your own protection parameters; if the current or voltage of the DUT is detected to exceed the set value during the output process, the protection mechanism will be activated immediately to avoid product damage.
When conducting a series of tests, test accuracy is often affected by voltage drops in the power transmission caused by cables, connectors, and distance. To mitigate this, the module is equipped with a Remote Sensing function that can automatically adjust the output to harmonize the difference between the actual test voltage and the set voltage.
Supports Vbus Over Current Protection (OCP) testing functionality. By setting current values within the 5A to 10A range (in 1mA steps, for durations under 3 seconds), it simulates an overcurrent condition at the Power Sink end to verify the overcurrent protection capability of the USB-C Power Source end. （Requires Chroma USB-C Signal Module A223810）
The supported Power Role monitoring function (Source/Sink) can automatically read the power role of the DUT through the Power Delivery protocol and carry out automatic/manual Power Role Swapping, helping users to confirm whether the DUT is supplying power or receiving power.
Fast Role Swap (FRS) effectively ensures that devices which require power are always powered and are not affected by other devices in the vicinity. The A223808 supports FRS through the USB-C hub, and displays the results on the screen in real time so that users can confirm whether the FRS function of the DUT is working as it should.
High conductivity beryllium copper improves the conductivity between components and reduces electromagnetic radiation leakage interfering with the DUT, in compliance with CE/EMC (Electromagnetic Compatibility) standards.
