  • Specification

The IT-M3100 series offers versatile DC power solutions with cutting-edge features that help meet the challenges of complex testing environments. It provides high output power in a compact 1U Half-Rack size, making it suitable for integration into automated test systems. The unit supports synchronous control of up to 256 channels, making it an excellent choice for large-scale testing setups.

Key capabilities include:

  • Synchronous Multi-Channel Control: Manage up to 16 units in a master-slave configuration, ideal for applications requiring simultaneous testing of multiple units or DUTs (Devices Under Test). Each channel can be independently controlled or synchronized across multiple power supplies.

  • Bidirectional Power Operation: It supports seamless switching between sourcing (power supply) and sinking (electronic load) modes. This function is critical for testing battery systems, power modules, and other energy storage devices.

  • High-Speed Measurement: Offers rapid voltage and current updates (up to 10 times per second) to handle dynamic load changes and transient tests effectively.

  • Modular Flexibility: The modular design allows users to mix and match output configurations, giving you the flexibility to test a wide variety of devices, from low-power components to high-power systems, using the same unit.

  • Battery Emulation & Test: The IT-M3100 series is equipped to simulate up to 99 batteries in series or parallel. Users can configure battery parameters (voltage, capacity, internal resistance, SOC) directly via the front panel, making it an excellent choice for simulating battery conditions in automotive, wearable, and energy storage systems.

  • Multiple Protection Mechanisms: The IT-M3100 includes a wide range of protections, including overvoltage, overcurrent, overpower, overtemperature, and grid fault protections. These safeguards ensure safe and reliable operation during long-term and high-stress testing scenarios.

  • 1U Half-Rack Ultra-Compact Size
    Compact design with up to 1500W output, saving space without sacrificing power or precision.

  • CC & CV Priority
    Offers flexible operation modes to prioritize current or voltage, ideal for high-speed power supply and testing without overshoot.

  • Multi-Channel Independent Control
    Supports up to 256 channels, allowing for synchronized operation or independent control across multiple units.

  • Battery Charging Function
    Integrated battery test with automatic shutdown based on set parameters (voltage, current, capacity, charging time).

  • Modular Design & Stacking Capability
    Easy stacking for a flexible system setup, enabling customizable configurations for various applications.

  • High-Speed Test with 10 Times/Second Update Rate
    Ensures fast and efficient testing across a range of applications, including dynamic waveforms.

  • Wide Range of Protection Features
    Includes OVP, OCP, OTP, OPP, and other safety features to ensure secure testing environments.
