Voltmat Power
Explore our top-tier 3kW to 4kW AC-DC stabilized switching power systems configured for local industrial grids and test facilities.
Tokyo's metropolitan and surrounding industrial zones—including Hachioji's electronics clusters, Kanagawa's research parks, and Ota City's precision manufacturing hubs—demand highly reliable, ripple-free power electronics. In these high-density manufacturing landscapes, space is at a premium and grid efficiency is strictly regulated under the Japanese Energy Conservation Act.
High-power systems in the range of 3000W to 5000W are the backbone of next-generation applications. From semiconductor Automated Test Equipment (ATE) and industrial laser systems to battery pack thermal aging stations, these units deliver stable DC power under harsh operational conditions. Our custom topologies are specifically engineered to withstand voltage fluctuations and minimize Total Harmonic Distortion (THD) to comply with local harmonic guidelines (JIS C 61000-3-2).
For applications requiring 3000W to 5000W, power system reliability hinges on topological design. Our design utilizes advanced Phase-Shifted Full-Bridge (PSFB) and LLC Resonant Converters. This dynamic allows for Zero Voltage Switching (ZVS), which minimizes switching losses and enables high power density packaging.
Additionally, active Power Factor Correction (PFC) circuitry ensures power factor ratings above 0.98 at nominal loads, reducing reactive power penalties from regional utilities like TEPCO (Tokyo Electric Power Company). Our industrial switching supplies offer configurable digital communication interfaces (RS485, CAN bus, or analog 0-5V/0-10V control inputs), enabling seamless integration into factory SCADA platforms and PLCs.
PF > 0.98 prevents harmonic pollution on the factory floor, complying with strict Japanese utility limits.
Multi-layered protections prevent damage during sudden load changes or thermal spikes.
Galvanic isolation up to 3000VAC ensures operator safety and noise immunity in control systems.
Industrial components destined for Tokyo's critical manufacturing lanes demand strict packaging protocols to protect fragile multi-layer PCBs and heavy magnetics (inductors, transformers) from environmental and transit stress. As a premier exporter located in Shanghai, we leverage convenient shipping infrastructure to streamline deliveries directly to Tokyo Port or Haneda Airport.
Every single power supply unit undergoes our multi-stage packaging process to prevent logistics failures:
Our quality assurance includes testing at multiple stages before dispatch, which enables us to achieve a 99.9% product qualification rate. This gives procurement managers complete peace of mind when integrating our systems into automated assembly lines.
Take a look inside our 10,000-square-meter facility, where we conduct rigorous, multi-stage manual and computer-controlled verification on all industrial units.

The industrial landscape in Tokyo is shifting towards automated, eco-efficient manufacturing. To prepare for these changes, our engineering team focuses on three key technological areas:
By integrating Silicon Carbide (SiC) Schottky diodes and MOSFETs into our 3000W-5000W architectures, we reduce switching losses by up to 45% compared to traditional silicon counterparts. This design allows our power supplies to run cooler and significantly increases the power density per cubic inch.
Smart factories rely on real-time telemetry to predict maintenance needs and minimize downtime. Our latest 3kW to 5kW systems support advanced serial monitoring protocols, including Modbus-RTU, CANopen, and PMBus. This enables plant managers to monitor internal temperatures, output current profiles, and voltage stability in real time.
Cooling fan failures are a common point of vulnerability in high-power setups. Our systems feature intelligent, speed-controlled cooling fans that adjust dynamically based on output load and ambient temperatures. This prolongs fan bearing life and minimizes acoustic noise levels in testing laboratories.
