Isolated power supply: 0V – 25V
Otii Ace Pro is an isolated programmable power supply that enables diverse use cases and power configurations. 

Connect several Otii Ace Pro devices in series and parallel to increase voltage capabilities. Measure systems where battery negative terminal is not the system ground. Measure with your energy source (for example your battery or energy harvester) in series while switching between measurement ranges.

Wide dynamic range: nA-5A

Measure accurately over 9 orders of magnitude from amps down to tens of nanoamps with the wide dynamic range of Otii Ace Pro.

Display and work with accurate visualization of the active and sleep modes on the same screen and in the same project. 

Current measurement resolution: 0.4 nA

Otii Ace Pro is a 2 quadrant source measure unit (SMU) with a constant voltage/constant current source and sink and a high precision multichannel multimeter.

It provides less than nA resolution current measurements with adjustable sample rate up to 50 ksps. The high sample rate and low step size enable accurate analysis of current consumption and inrush current.  

Adjustable sample rate up to 50 ksps

Current measurement sample rate for Otii Ace Pro is adjustable. 

No burden voltage

Otii Ace Pro has active voltage regulation and compensates for burden voltage.

Compact and lightweight for the desktop and field

Otii Ace Pro measures 10,9cm x 14,4cm x 4,4cm (WxLxH) and weighs 450 grams, just as Otii Arc. It is designed for the office, the lab, and usage at home, as well as field measurements. Also, the innovative mechanical design allows for efficient heat dissipation, hence no fan is needed and therefore no noise. 

Power it by USB C.

Best in class multiplatform software

Otii software runs on macOS, Windows and Ubuntu. It is build for ease of use, accessibility and durability for those long measurements. 

Otii software

Otii software for Otii Ace Pro is feature-packed, multi-platform and easy to use.

Software for test and measurement should be robust, versatile and easy to use – and we are here to prove that can be done. Use Otii desktop application with no subscription and no login.  Measure, analyze, share projects and collaborate with your team.  

Desktop application for macOS, Windows and Ubuntu

The Otii software is the multiplatform backbone of Qoitech’s Otii Product Suite. Designed to interface with Otii hardware to provide a powerful and comprehensive application for developers and engineers to record, visualize, and analyze the power consumption of battery-driven devices in real-time. 

Easy to start, easy to use

From unpacking Otii Ace Pro to measurement in less than 1 minute. Download Otii software, open the desktop application and start measuring. No logins. 

Sync and compare multiple recordings

With Otii software you can easily synchronize your visualizations and compare multiple power measurement recordings, add new recordings to existing projects seamlessly, and perform extended measurements and benchmarks. Seeing results in this manner is an excellent way to evaluate the efficiency of your project.

Synchronize expansion port and power measurements

Connect your device to Otii Ace Pro’s expansion port. Log GPIs, ADC subsystem measurements and UART logs. All the recordings are synced to the current and voltage graphs making it easy to correlate power consumption to the application state.

Add Otii Toolboxes to elevate the hardware to battery simulator

Otii software can be extended with Otii Toolboxes, which enable scripting (Otii Automation Toolbox) and battery simulation and testing (Otii Battery Toolbox). The Otii Toolboxes can be purchased as perpetual licences or monthly/yearly subscriptions.
