Headquartered in 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. Our advanced power units serve as essential auxiliary components and diagnostic devices across large-scale clean energy grids, including hydro power systems, solar microgrids, and electric vehicle testing platforms.
As standard grids adapt to remote, high-demand installations, MYAMI has developed high-power DC sources, variable frequency AC supplies, and thermal monitoring modules that guarantee the stability and continuous verification of excitation lines, gate controllers, and monitoring sensors inside major hydroelectric dams and pumped-storage power stations.
Our core engineering capabilities focus on four pivotal pillars. By integrating these systems, we allow hydro power plant developers and electrical research institutes to perform precise simulation, calibration, and commissioning of control loops and safety systems.
Featuring multi-digit LED displays, ultra-low ripple, and rapid transient response, engineered for precision electronic R&D, semiconductor evaluation, and PCB debugging. Essential for simulating battery backup lines and digital logic controls inside turbine housings.
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, hydro excitation systems testing, and heavy-duty component burn-in verification.
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-hydro hybrid inverter synchronization testing.
Hydroelectric power generation relies heavily on high-voltage and high-current regulation. Excitation systems are the brain of the generator, controlling the field current to maintain a stable output voltage of the hydro turbine generator. MYAMI’s heavy-duty, rack-mounted DC power supplies, which scale up to 800A, are ideal for excitation winding testing, coil resistance measurement, and simulated system commissioning.
In addition, pumped-storage hydropower plants require precise variable frequency controls for startup operations. Our programmable variable frequency AC power supplies simulate real grid disturbances, allowing engineers to verify frequency-dependent relays, synchronization units, and emergency shutdown actuators without risking physical damage to main grid elements.
Utilizing high-precision digital display bench laboratory power supplies to deliver stable voltage references for testing proportional control valves, servo controllers, and feedback loops.
Leveraging multi-channel thermocouple temperature data loggers (such as WS30 and Handheld 10-channel models) to track rotor temperature gradients, stator windings, and bearing friction profiles during continuous operations.
Injecting high currents using rack-mounted DC units to run thermal test profiles on field coils, testing insulation parameters with Hi-pot testers under maximum thermal conditions.
From raw material inbound inspection to advanced software calibration, MYAMI implements a rigid 24-step quality assurance framework to ensure every industrial instrument operates flawlessly in critical environments.

Procuring industrial-grade test equipment for utility sectors requires more than just high-quality components; it requires compliance, local technical support, and structural scalability.
By leveraging the unparalleled semiconductor and manufacturing ecosystem of Shenzhen, MYAMI guarantees shorter lead times for highly customized configurations. From small benchtop testing modules to full-rack multi-kilowatt cabinets, we integrate vertical production pipelines that cut down distribution costs.
Our instruments conform strictly to international grids standard. Our production line is ISO9001 certified. The power supplies contain internal filters matching standard EMC directives, CE certifications, and meet RoHS compliance requirements for minimized ecological impact.
We work in tandem with overseas distributors, offering standard SDK codebases, custom programming APIs (SCPI, LabVIEW drivers), and detailed schematics for local engineering integration, ensuring seamless commissioning in local grids.
As the global power sector transitions to digitized, intelligent control, several critical technological trends are shaping the future of hydroelectricity:
