Explore our primary industrial instrumentation and programmable power supplies selected for critical system calibration and hardware-in-the-loop evaluation.
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.
As smart grids evolve globally, the demands placed upon substation automation equipment—such as Bay Controllers, Protection Relays, Terminal Units (RTUs), and Remote Monitoring Networks—require absolute stability under volatile ambient conditions. Our specialized engineering portfolio is developed specifically to empower testing labs, electrical commissioning teams, and power grid equipment OEMs with reliable calibration systems and programmatic power infrastructure.
Featuring multi-digit LED displays, ultra-low ripple, and rapid transient response, engineered for precision electronic R&D, semiconductor evaluation, and PCB debugging.
Delivering high-current, high-voltage DC/AC regulated power supplies built for industrial motor drives, electroplating rectifiers, and heavy-duty component burn-in testing.
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 and technical institutes.
The modernization of utility grids toward the Smart Grid paradigm requires a foundational transition from legacy copper-wired substations to optical-fiber based digital substations. Under the IEC 61850 standard framework, physical wiring is replaced by high-speed Ethernet communication buses carrying GOOSE (Generic Object Oriented Substation Events) and Sampled Values. This structural shift has completely redefined global procurement needs. Technical procurement directors, utility operators, and EPC contractors demand diagnostic and power simulation equipment that offers unparalleled stability, safety, and integration protocols.
Reliable power supplies and high-accuracy diagnostic instruments are critical during the three main phases of substation engineering: Factory Acceptance Testing (FAT), Commissioning / Site Acceptance Testing (SAT), and preventive maintenance cycles. Testing relays, monitoring remote telemetry units (RTUs), and validating power management subsystems require stable variable DC/AC sources that can simulate extreme grid behaviors, drop-outs, and rapid load changes without introducing harmonics that might yield false results.
Substation automation equipment must operate in highly unstable environment regimes—ranging from freezing sub-zero arctic substations to desert wind farms experiencing ambient temperatures above 50°C. Therefore, the variable power supplies used to validate these devices must have precise thermal margins and feature robust Over-Temperature Protection (OTP) and Over-Voltage Protection (OVP). Industrial motor drives, electroplating rectifiers, and switchgear actuators require specific power characteristics during startup. Our variable high-voltage and high-current power systems are specifically optimized to supply stable power despite these severe back-EMF spikes.
Furthermore, EV infrastructure deployment presents a critical integration challenge for the distribution grid. Battery simulators and regenerative electronic loads are vital for simulating transient loads on the substation's secondary distribution transformers. This allows engineering firms to test grid-edge stabilizing hardware and smart inverters prior to active commercial deployment.

Strategic technological milestones targeting high integration density, digital control loops, and autonomous diagnostic architectures.
Transitioning primary switching modules in variable AC/DC power sources to Wide Bandgap (WBG) Silicon Carbide (SiC) technology. This increases efficiency to > 94%, reduces spatial footprint by 40%, and guarantees rapid load transient times essential for simulating grid faults.
Expanding the native communication layer of all test instrumentation. Integrating native Modbus, SCPI, EtherCAT, and PROFIBUS interfaces directly alongside current CAN, RS485, and RS232 options for seamless PLC integration in automated factory test floors.
Developing internal firmware modules that monitor power device parameters (ripple, thermal drift, switching cycle degradation) to predict hardware failures. This guarantees utility lab testing systems remain continuously calibrated without downtime.
Every MYAMI system is engineered with strict multi-layer protection protocols (OVP, OCP, OTP, and short-circuit safeguards) and complies with international safety and quality standards, including CE, RoHS, and ISO9001. Integrated with standard industrial control protocols (RS485, RS232, and CAN communication), our equipment seamlessly connects to automated production lines and central PC control systems.
Currently, MYAMI serves research institutions, automotive OEMs, aerospace contractors, and electronics manufacturers across North America, Europe, East Asia, and the Middle East. High-precision industrial processes require a highly localized technical network to guarantee minimum Down-Time (MTTR). In response, we have optimized our supply-chain partnerships, enabling local technical consultations, swift spare part dispatch, and remote debugging services for global commercial projects.
