High-performance Cabinet and Laboratory DC Power Supplies Optimized for Automotive Electrification and Avionics Testing.
Headquartered in Shenzhen, China, Shenzhen Myami Power Technology Co., Ltd. (MYAMI) is a globally recognized, technology-driven manufacturer and solution provider specializing in high-precision, industrial-grade DC power supplies and electrical test instruments. Engineered to meet rigorous safety protocols and demanding laboratory standards, MYAMI bridges the gap between complex semiconductor research, high-voltage component testing, and scalable industrial automation.
As Nagoya and the wider Aichi Prefecture undergo a generational shift toward electric vehicles (EVs), collaborative robotics, and aerospace technology, our hardware solutions are specifically configured to meet Japanese engineering criteria. By delivering low-ripple, highly responsive power conversion units, we support local system integrators and tier-1 manufacturers in implementing high-throughput production lines.
Understanding the technical challenges of the Chubu region's manufacturing transformation.
Nagoya, the capital of Japan's Aichi Prefecture, stands as the global epicentre of automotive and manufacturing craftsmanship, known in Japan as Monozukuri. As the home to the world's leading automotive OEMs and their vast tier-1 networks (including Denso, Aisin, and Toyota Boshoku), the region demands absolute reliability from its test equipment.
The transition from Internal Combustion Engines (ICE) to Battery Electric Vehicles (BEVs) and Fuel Cell Vehicles (FCVs) has fundamentally shifted test protocols. Modern automotive architectures have migrated from 12V and 24V networks to 400V, 800V, and even 1000V drivetrain systems. This rapid transition requires highly configurable, high-power programmable DC power sources capable of simulating dynamic battery profiles, voltage sags, and transient cranking spikes.
Furthermore, Nagoya's aerospace cluster—which accounts for a significant portion of Japan's aviation manufacturing industry—requires high-reliability DC power supplies to validate actuation systems, flight computers, and cabin electronic payloads under simulated extreme environmental variables.

How our systems are deployed in real-world testing environments across the Nagoya area.
Evaluating On-Board Chargers (OBC) and Battery Management Systems (BMS) requires high-accuracy voltage output. Our programmable cabinet units simulate a battery pack's internal resistance and charge/discharge curves. This allows Japanese automotive engineers to test OBC protection mechanisms against real-world anomalies.
Nagoya’s precision machining suppliers rely on electroplating rectifiers for anti-corrosive coatings. Providing low ripple current guarantees uniform deposition rates, eliminating surface micro-voids in precision machined parts destined for high-stress aerospace applications.
For manufacturing power semiconductor modules (SiC & GaN MOSFETs), our high-voltage units deliver stable bias voltage up to 6000V. This enables parallel component stress testing with minimal noise injection, yielding clean leak-current measurements in R&D labs.
Rigorous quality steps that align with ISO9001 and the high QA expectations of the Japanese supply chain.
Every power system shipped by MYAMI undergoes ten distinct manufacturing and testing phases. We recognize that in Japanese high-tech sectors, single-digit PPM failure rates are the standard. Consequently, our testing infrastructure leverages digital oscilloscopes, LCR meters, and high-pot testers from industry-certified calibration houses to qualify every unit.
How current high-frequency switching technology supports future test needs.
Industrial power systems are transitioning from linear topologies to high-frequency switching converters based on Silicon Carbide (SiC) and Gallium Nitride (GaN) substrates. This evolution enables MYAMI to reduce the physical volume of cabinet units while maintaining efficient heat dissipation under continuous full-load conditions.
Integrating Modbus-RTU, RS485, and CAN communication interfaces directly into our programmable lines allows automotive and industrial system integrators to configure automated test setups using LabVIEW, Python, or PLC networks. This compatibility simplifies complex multi-channel burn-in runs in mass production lines.

Expert technical answers regarding programmable DC power source integration and application safety.
To counter voltage drops across long connection lines in high-current test setups, MYAMI supplies feature remote sensing terminals. Connecting the sensing wires directly to the load terminal lets the power supply's control loop measure the exact voltage at the load. It then automatically raises its output voltage to compensate for cable losses. This ensures the target voltage remains constant at the load terminals under varying load currents.
Most MYAMI programmable DC power units come equipped with standard industrial interfaces, including RS232, RS485, and CAN. They support standard SCPI commands or Modbus-RTU protocol definitions. This allows for direct connection with PLCs, central control computers, or test software suites like LabVIEW, enabling remote control and automatic data collection.
High ripple and noise can introduce measurement errors or cause spurious state changes in sensitive digital circuits during semiconductor characterization or PCB R&D. MYAMI benchtop and high-precision DC sources employ high-efficiency filtering circuits. This delivers a low-noise profile (down to a few millivolts RMS), preventing power supply noise from interfering with the measurements of your device under test.
Yes. All MYAMI industrial-grade systems feature built-in hardware protection circuits, including Over-Voltage Protection (OVP), Over-Current Protection (OCP), Over-Temperature Protection (OTP), and short-circuit protection. These limits can be programmed via the interface, ensuring that the supply shuts down its output if a parameter crosses the safety threshold. This protects expensive devices under test, such as EV control units or aerospace modules.
Our manufacturing facilities are certified to the ISO9001:2015 quality standard. Individual product series carry international safety markings, including CE and RoHS compliance, ensuring they meet the safety and environmental criteria required by Japanese, European, and American lab operators.
