PCIe-SSD Power Adapter Plus

The PCIe-SSD Power Adapter Plus (PSPA+) adds the power consumption measurement on top of PCIe-SSD Power Adapter (PSPA). With this integrated adapter, the users can easily measure the power consumption during the different power states: active, idle, no operational and etc. via the simple script instructions provided by ULINK DriveMaster without any extra installation and any power meter operation knowledge.
