Otii Ace Pro DC Power Analyzer

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
office, lab, usage at home, and field measurements. The innovative mechanical design allows for efficient heat
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
