Product Details


Otii Ace Pro is a versatile power supply and measurement instrument designed for precise voltage (up to 25 V) and current (up to 5A) sourcing. Simultaneously measuring with a high sample rate (50ksps) and low step size, it computes power and energy, allowing engineers and developers to optimise device energy consumption and battery life.


Key Features and Benefits of Otii Ace Pro

  • Quick Installation and Plug-and-Play: Enables users to start measuring in less than a minute.
  • Isolated Power Supply: Facilitates diverse use cases and power configurations, supporting a range of 0-25 V.
  • Expandable Voltage and Current: Connect multiple devices in series and parallel to increase voltage and current capabilities.
  • High-Resolution Current Measurements: Offers 0.4nA resolution with an adjustable sample rate of up to 50ksps.
  • Wide Dynamic Range: Current measurements span from 0.4nA to 5A.
  • Accuracy: Current measurement accuracy of ±(0.05% + 25nA).
  • Active Voltage Regulation: Ensures no burden voltage during measurements.
