The USB voltages regulator provides accuracy digital displays for voltage, current, and frequency, giving you exact readings during testing and debugging and reducing guesswork. It functions as a regular boost power supply with builtin protections to safeguard both the regulator and your connected devices, including overvoltage, overcurrent, over power, over temperature, and undervoltage protections. It includes a constant current mode that can charge various small rechargeable batteries across a range of 0.6V to 30V with a maximum output of 15W, offering flexible charging capabilities for portable projects. The regulator features a portable, compact form factor and user friendly interfaces, making it a reliable companion for on the go troubleshooting, fieldwork, and rapid experimentation. Benefits and rationale Precise measurements reduce testing time and help you set exact operating conditions for your projects. Built in protections minimize the risk of damage to both the device under test and the regulator itself. The CC charging option supports a variety of small batteries, adding versatility to your workshop or field toolkit. Lightweight and portable design supports easy transport and quick setup in different work environments.
