Voltmat Power
Engineered for absolute reliability, precision control, and ultra-high efficiency. Explore our flagship single output industrial power systems.
As a leading China single output power supply manufacturer and exporter, our 10,000 square meter state-of-the-art facility in Shanghai leverages premium logistical access to global markets and elite engineering pools. For a decade and a half, we have specialized exclusively in industrial-grade, high-power regulated power supplies.
Our design methodology relies heavily on robust topology designs including LLC resonant converters, active power factor correction (APFC), and digital DSP controls. By maintaining control over the entire supply chain—from high-frequency transformer winding to thermal management testing—we ensure that every power unit delivered satisfies the stringent conditions of modern heavy industry.

Real visual breakdown of our operations in Shanghai, demonstrating systematic traceability, computerized test rigs, and environmental stressing.
Why global system integrators and tier-one EPC contractors source high-power DC systems from specialized Chinese clusters.
Our Shanghai hub utilizes direct, localized sourcing for raw magnetic cores, high-reliability copper windings, and advanced power semiconductor substrates. This cuts lead times for large-scale projects down to 2–4 weeks compared to western counterparts which struggle with magnetic wire and casing lead times.
Unlike modular, low-power standard catalog items, industrial setups require extreme thermal and structural flexibility. Our design processes allow customizable input parameters (such as 3-phase wide input ranges 380V/480V AC) and programmable communication busses (RS485, CAN, Modbus-RTU) integrated natively at the PCB level.
Every power supply series features built-in active protections including short-circuit self-recovery, precise over-current foldback limiting, thermal throttling at 85°C internal heatsink levels, and heavy-duty transient voltage suppressors (TVS) to absorb incoming lightning and line surges.
The global power conversion landscape is transitioning from passive analog architectures to software-defined power systems. Key trends reshaping our manufacturing floor include:
"We design with headroom. When a client operates an 8000W system at continuous 100% duty cycles in a warm industrial environment, component degradation accelerates. By sizing magnetics and switches with a 25% safety buffer, we ensure the unit outlasts standard warranties under standard operating stress."

Real-world operational configurations for our high-power single output DC power supplies across major global sectors.
High-current output reliability is critical for continuous electro-extraction and anodizing baths. Our 12V-30V high-current single output series delivers ripples of less than 1% Vp-p, ensuring uniform deposition rates and avoiding structural micro-defects in processed materials.
Typical Choice: 30V-600W / 24V-10000W Adjustable DCBattery pack testing requires constant voltage (CV) and constant current (CC) automatic crossovers. The adjustable 12V-600V modules allow engineers to configure battery charging envelopes precisely, avoiding over-voltage degradation during charging cycles.
Typical Choice: 1500W-2000W DC Regulated Bench SupplySimulating high-altitude DC buses requires clean, high-voltage outputs up to 800V-1000V. Our digital display series provides high resolution (1V/1A precision steps), galvanic isolation up to 3KVAC, and rapid safety shutoff relays.
Typical Choice: 800V-24000W / 300V-12000W Single OutputFully customizable power supplies for automation, heavy machinery, and dedicated test bays.
How we protect critical hardware during intercontinental transit and optimize supply-chain reliability for international buyers.
Industrial power supplies house sensitive electronic boards, high-mass transformers, and structural casings. Mishandling during ocean transport or multi-stage truck transfers can cause internal damage. To counter this, our logistics department packages every shipment using a strict multi-layer protocol:
Located in Shanghai, we have access to major logistics networks:
Detailed engineering answers for system integrators, design leads, and global procurement departments.
Single output configurations provide higher conversion efficiency, better load regulation, and reduced component complexity. Because the control loop is dedicated to a single voltage rail, it can respond to load changes without cross-regulation issues. Additionally, single output designs allow for larger transformers and filter circuits within a compact chassis, improving thermal management and system MTBF.
We execute a two-stage inspection protocol. First, automated tester systems evaluate component-level tolerances, primary insulation, and loop responses. Second, skilled engineers perform physical inspections and run the unit in active test beds. Before leaving our Shanghai factory, every unit undergoes a full-load burn-in run inside our temperature-controlled aging bay to catch infant mortality failures.
Yes. Our adjustable high-power models (like the 12V-600V and 24V-1000V series) feature fine-tuning potentiometers and support external analog controls (0-5V, 0-10V, or 4-20mA signals) or digital interfaces (RS485, CAN bus, Modbus) for real-time monitoring and integration into automated PLC testing loops.
Our industrial lines include a robust protection suite: Overload Protection (OLP) with Hiccup/Foldback modes, Overvoltage Protection (OVP), Overtemperature Protection (OTP) that disables output if junction temperatures exceed safe limits, and short-circuit protection with automatic recovery once the fault is cleared.
Because humidity in shipping containers can damage copper windings and components, we wrap units in moisture-proof barrier film with silica desiccant packets, package them in heavy double-wall cardboard boxes, and secure them inside reinforced wooden frames. This keeps the cargo dry and secure during transit.
All standard products carry a 1-year factory warranty. As a top-rated Shanghai enterprise, we provide email and video consultation to walk field engineers through commissioning or diagnostics, and ship replacement modules directly to keep downtime to a minimum.
