Otii Ace Pro Otii Ace Pro is a development tool for energy optimisation of battery-driven and energy-harvesting devices. It is an isolated power supply and a measurement unit that can precisely source voltage (up to 25 V) or current (up to 5 A) and simultaneously measure voltage and current with a high sample rate (up to 50 ksps) and low step size. It computes power and energy that enables engineers and developers to easily see and optimise their devices' energy consumption and battery life under test. Otii Ace Pro can be upgraded with Otii Toolboxes, software licenses that elevate the instrument into specialised tools such as battery profiler and simulator, or automation tools. It can be used in product development, test and verification, quality assurance and maintenance (for example as part of continuous integration set-up), and in technical sales. The Otii Ace Pro measures 10.9 cm x 14.4 cm x 4.4 cm (W x L x H) and weighs 450 grams. It is designed for the <BR/>office, lab, usage at home, and field measurements. The innovative mechanical design allows for efficient heat <BR/>dissipation, so no fan is needed resulting in low noise. A USB-C cable and a USB-A to USB-C adapter are included in the package Features The Otii software, an easy-to-use desktop application for Ubuntu, Windows, and macOS Quick install, plug-and-play setup, and start measuring in less than a minute The isolated power supply enables diverse use cases and power configurations, 0 V to 25 V Connect several devices in series and parallel to increase voltage and current capabilities Providing 0.4 nA resolution current measurements with an adjustable sample rate of up to 50 ksps Wide dynamic range: 0.4 nA to 5 A Current measurement accuracy: ±(0.05% + 25 nA) Active voltage regulation, no burden voltage Measure systems where the battery negative terminal is not the system ground Measurements continuously synchronized with debug logs from the device under test, collected via UART in the expansion port Real-time analysis; scroll, zoom, and select parts of the current consumption and debug logs while measuring Record and compare multiple recordings Battery life calculator Support for in-line measurementsShare the Otii project and recordings for measurements or view by colleagues Undo/redo functionality Support for multiple Otii hardware in one Otii project Configurable UI Fully responsive UI during heavy data measurement load (multiple streams, long recordings) Offline license mode Made in Sweden Use Otii Ace Pro every day to: Power your devices under development<BR/>Energy profile microcontrollers, sensors, devices and electronics up to 25V in real time and over time<BR/>Optimise sleep current, extend battery life<BR/>Measure inrush current <BR/>Measure component leakage current over time <BR/>Design power-efficient hardware, firmware and software through regression testing<BR/>Troubleshoot your hardware and software Otii Ace Pro is perfect for: IoT sensors and hubs Mobile phones Wearables Development boards Consumer electronics <B> </B>
