Voltmat Power
Premium OEM adjustable power supplies featuring high stability, wide voltage spans, and efficiency ratings up to 89%
In the contemporary industrial and commercial landscape, the demand for high-power regulated low voltage power supplies is experiencing unprecedented growth. A Custom OEM Low Voltage Power Supply Factory acts as a critical technological backbone for multiple sectors including automated manufacturing, EV charging infrastructure, medical diagnostic machinery, defense installations, and data center structures. Historically, low voltage power was confined to light electronics. Today, industrial switching topologies allow systems to scale output capacities dynamically from simple 90V-400W configurations up to massive 1000V-24000W adjustable DC architectures.
Globally, the push towards electrification and digital transformation has forced factories to transition to power supplies that guarantee high conversion efficiencies (typically 88% to 89% and beyond) with minimal harmonic distortion. The integration of advanced power semiconductor devices, such as Silicon Carbide (SiC) and Gallium Nitride (GaN), is shifting the paradigm of low voltage power design. Factories around the globe are adjusting to this transition by developing custom switching power supplies that feature highly digital displays, precise regulation controls, and modular topologies designed for localized industrial environments.
We provide tailormade engineering for specific applications ranging from 12V up to 1000V DC output, optimizing structural layout, dynamic response times, and cooling paths to suit custom enclosures.
Headquartered in Shanghai with a 10,000 square meter state-of-the-art facility, specializing in designing and scaling high-power regulated systems with a robust global export channel.
Every product undergoes dual-stage testing—both automated computer metrics and manual QA verification—before leaving the assembly floor, ensuring zero field defects.
Inside our Shanghai factory: standard operational procedures that govern our customized OEM assembly lines
As industrial processes demand absolute reliability, OEM developers must pioneer advanced electrical engineering solutions. Achieving stable low voltage high-current output requires a deep understanding of thermal management, switching topologies, and electromagnetic interference (EMI) containment. Our 10,000 square meter Shanghai factory utilizes automated processes like the Automatic Soldering Machine and Canning machine to achieve unparalleled consistency in component placement and environmental sealing.
Traditional linear regulated power supplies offered clean output waveforms but suffered from extremely poor efficiency, often wasting up to 50% of the input power as heat. The advent of High-Frequency Switching Mode Power Supplies (SMPS) changed everything. By modulating the duty cycle using Pulse-Width Modulation (PWM) controllers, our current generation of custom power supplies achieves efficiency rates of 88% to 89%. This reduction in energy waste translates directly to lower operating costs and a significantly reduced thermal load inside industrial control cabinets.
For custom configurations operating at higher power boundaries—such as our Output 110V-20000W Industrial Regulated DC Power Supply or the massive Industrial Output 1000V-24000W Adjustable DC solution—we deploy a Phase-Shifted Full-Bridge (PSFB) zero-voltage switching (ZVS) topology. This approach minimizes switching losses across the primary power MOSFETs, ensuring that the supply can operate continuously under heavy load profiles without degradation.
To guarantee a 99.9% qualification rate, we implement a strict quality management system (QMS) across all 19 stages of our production line. Quality control starts at the raw material stage with precise Wire Cutting and custom coil winding using a modern Winding Machine. PCB layouts are populated through a unified Plug-In process, followed by precision flow soldering with our Automatic Soldering Machine to eliminate cold solder joints.
After mechanical assembly, the boards are treated with customized compound formulas using a high-throughput Glue Filling and Canning machine. This encapsulating layer offers triple protection: isolating sensitive trace lines from industrial dust/chemical moisture, absorbing mechanical vibration, and aiding in heat dissipation. All completed power modules undergo dual testing phases:
The protective engineering continues even after production. Industrial high-power supplies are highly susceptible to shipping damage. Our custom logistical packaging is engineered to mitigate these risks completely:
High-capacity custom low voltage power supplies are utilized in various localized industrial scenarios across the globe:
Addressing engineering specifications, customization timelines, and compliance standards for global buyers
We provide customization options across multiple dimensions, including input voltage ranges (110V/220V/380V/480V AC), output voltages (ranging from 12V DC up to 1000V DC), output current limits, display interfaces (analog, digital LED, or touchscreen), communications protocols (RS485, Modbus, CAN bus), and physical enclosure dimensions to suit specific spatial constraints.
All power units are equipped with a multi-layered protection suite that includes Over-Voltage Protection (OVP), Over-Current Protection (OCP), Over-Temperature Protection (OTP), and Short-Circuit Protection (SCP). Thermally, we utilize auto-controlled dual cooling fans and internal heat sinks. The protective conformal coating applied via our canning machines shields the internal circuitry from dust and corrosion.
Our power supplies maintain a flat efficiency curve, hovering between 88% and 89% when operating within a 20% to 100% load window. This is achieved through active power factor correction (PFC) circuitry and synchronous rectification stages, preventing efficiency drops at fractional loads.
Automated tests using DC Power Supply Testers detect calibration anomalies and waveform irregularities, while manual inspections target structural anomalies, connector fits, and component alignments. This combined QA model allows us to achieve a 99.9% factory qualification rate, reducing warranty returns and field failures.
