Headquartered in the global electronics capital of Shenzhen, China, Shenzhen Myami Power Technology Co., Ltd. (MYAMI) is a technology-driven manufacturer and solution provider specializing in high-precision, industrial-grade power supplies and electrical test equipment. Designed for engineering rigor, MYAMI bridges the gap between complex electronic research, high-voltage component testing, and scalable industrial automation.
As a global manufacturer and exporter, we design products that serve as the backbone for modern manufacturing lines, university laboratories, and testing centers worldwide. By combining advanced digital control loops, cutting-edge semiconductor materials, and robust mechanical structures, MYAMI guarantees reliability and precise electrical output under the most demanding workloads.
Addressing the evolving demands of modern electrical engineering through specialized focus areas, our research and production capabilities are divided into four dedicated structural divisions.
Featuring multi-digit LED/LCD displays, ultra-low ripple, and rapid transient response. Engineered specifically for precision electronic R&D, semiconductor evaluation, and PCB debugging.
Delivering high-current, high-voltage DC/AC regulated power supplies (ranging up to hundreds of volts and amperes). Built for industrial motor drives, electroplating rectifiers, and heavy-duty component burn-in.
Providing specialized DC power units, battery simulators, and variable AC power sources engineered for Electric Vehicle (EV) On-Board Chargers (OBC), BMS evaluation, and solar inverter testing.
Supplying complementary test bench solutions, including digital oscilloscopes, multimeters, and specialized AC voltage regulators for global laboratories, aerospace organizations, and technical institutes.
The global demand for high-reliability programmable power systems is undergoing a monumental shift. Historically constrained to simple electronics validation and educational laboratories, programmable power supplies are now foundational units in modern manufacturing and development lifecycles. Key industries such as automotive electrification, photovoltaic systems, aerospace engineering, and advanced silicon testing require power delivery devices with micro-second dynamic response times and high efficiency.
In North America and Europe, the surge in Electric Vehicle (EV) infrastructure development has created an intense need for bidirectional programmable DC sources capable of simulating battery pack charge/discharge curves up to 1000V. Concurrently, the growth of localized semiconductor fabrication and GaN/SiC power device characterization requires test equipment that maintains strict low ripple/noise limits under high-current transients.
Shenzhen MYAMI Power sits at the focal point of this industry transformation. By coupling Chinese manufacturing efficiency and supply chain integration with top-tier engineering principles, we supply solutions that match the highest performance requirements of global OEMs, without the premium legacy costs associated with western test instrument manufacturers.
Historically, linear power supplies provided high precision and ultra-low noise but were inefficient and bulky. Switching power supplies offered higher power density but suffered from high output noise. MYAMI's hybrid topologies offer the best of both worlds: highly efficient switching pre-regulation combined with precise linear post-regulation. This results in laboratory linear power supplies with high accuracy, high power-density profiles, and minimal thermal output.
By integrating Silicon Carbide (SiC) and Gallium Nitride (GaN) field-effect transistors into our high-power platforms, MYAMI decreases switching losses and increases thermal thresholds. This integration allows us to package high-wattage power supplies (up to 1800W adjustable) in smaller form factors, including space-saving 1U half-width rack configurations.
Analog control loops are prone to thermal drift and component aging. MYAMI uses ARM Cortex and FPGA processors to execute high-speed digital control loops. This ensures fast programmable voltage slew rates, microsecond transient response recovery times, and precise multi-digit calibration.
As energy systems integrate more solar inverters and battery storage networks, modern programmable power supplies must evolve. MYAMI is developing regenerative electronic loads and bidirectional DC sources. These upcoming units will sink energy and feed it back into the local AC grid with high efficiency, reducing thermal load and utility costs during long-term battery burn-in tests.
We build more than stand-alone instruments. Our team designs integrated systems that control, monitor, and record complex electrical parameters.
Using MYAMI high-power DC programmable units combined with variable AC frequency sources, engineers can simulate real-world grid conditions (surges, dips, frequency drops) and battery back-EMF state configurations. This setup ensures that OBC designs can handle grid instability and operate reliably.
With standard RS485, RS232, and CAN interfaces, MYAMI equipment integrates into manufacturing lines. Using Modbus or SCPI instruction sets, central computers can automate voltage profiles, capture transient data, and output automated pass/fail results for high-volume component manufacturing.
Evaluating semiconductor reliability requires running devices under high thermal and electrical stress for thousands of hours. Our power systems feature active cooling, low thermal drift, and multi-layer safety features (OVP, OCP, OTP) to run these critical tests without interruption.
To guarantee reliable performance, MYAMI controls every step of production. Below is our visual workflow showing the progression from raw components to finished, calibrated instruments.

Testing accuracy requires calibrated reference instruments. MYAMI maintains a complete quality control laboratory, utilizing these instruments to test, verify, and document every production run.
Every power supply we manufacture complies with international safety and quality standards, including CE, RoHS, and ISO9001. Our laboratory testing verifies voltage and current linear stability, transient spikes, thermal insulation resistance, and electromagnetic compatibility (EMC).
This testing ensures our equipment operates reliably when integrated into automated production lines, central PC control networks, or research labs.
