This delivery imposed extremely high requirements on output capability, stability, and operational safety, and once again demonstrates ITECH’s engineering maturity and proven ability to deliver stable, reliable solutions for ultra-high-current applications.

01 High-Current Platform Designed for Cutting-Edge Industries

As renewable energy, electrochemical processes and advanced manufacturing continue to push toward higher power densities, more industries are moving toward megamp-level current requirements. The IT-M3900D Series high-power programmable DC power supplies, together with the IT-M3900C Series bidirectional programmable DC power supplies, are now widely deployed across multiple high-end sectors.

 ♦ Green hydrogen & electrolyzer production lines

 ♦ SOFC systems & superconducting equipment

 ♦ Electroplating, smelting & industrial electrochemistry

 ♦ High-power e-drive and power electronics

 ♦ Connector, fuse and terminal temperature-rise validation

Across all these applications, one requirement is universal: a stable, sustainable and engineering-grade high-current platform.

02 Core Engineering Challenges in High-Current Scenarios

Although use cases vary dramatically across industries, megamp-level systems consistently face similar engineering challenges:

♦ High-current density vs. system size & cost

Massive currents require heavier cabling and higher thermal overhead, making power density a central design target.

♦ Measurement accuracy affected by voltage drop

Long cable runs and thick conductors introduce voltage drops that compromise measurement precision.

♦ Long-duration reliability for 24/7 operation

Continuous 24/7 operation imposes strict requirements on system robustness and protection design.

♦ System controllability at megamp level

Parallel operation, current sharing, dynamic response and fault isolation become mission-critical.

These challenges mean high-current systems must not only deliver power, but sustain and stabilize it over long operational cycles.

03 IT-M3900D / IT-M3900C: A Proven Solution for Engineering-Grade High-Current Applications

The IT-M3900D high-power DC supplies and IT-M3900C bidirectional DC supplies provide a stable foundation for megamp-level applications.

♦ High power density for compact system design

1U/6 kW and 2U/12 kW units deliver significant current in a compact footprint, reducing facility and distribution overhead.

♦ Modular scalability from 100 A to 10,000 A+

Flexible parallel operation supports a unified platform from R&D to mass production, reducing lifecycle maintenance cost.

♦ High accuracy & low ripple with line-drop compensation

Ensures stable and repeatable output performance for precision-critical applications.

♦ Seven-layer protection for long-duration stability

OVP / OCP / OPP / UCP / UVP / OTP / Reverse SENSE
A multi-layer protection chain ensures safe, continuous operation at extremely high currents.

♦ Bidirectional energy capability (IT-M3900C)

Supports discharge, energy regeneration and pulse absorption—essential for e-drive, storage and electrochemical applications.

The successful delivery of this mega-ampere-level system to a leading hydrogen energy manufacturer once again demonstrates the engineering maturity of the IT-M3900D series high-power programmable DC power supplies and the IT-M3900C series bidirectional programmable DC power supplies in high-current applications.
Looking ahead, ITECH will continue delivering higher power density, stronger platform scalability and more robust system architectures to support the industries shaping the future of high-power and high-efficiency innovation.
