Winsun / Shanghai Winsun Power Switching Power Supplies

Winsun / Shanghai Winsun Power industrial switching power engineering

Shanghai Winsun Power Supply Technology Co., Ltd. has developed and manufactured industrial switching power supplies since 2002.

Operating from modern facilities in Minhang District of Shanghai, the enterprise supplies power units for telecommunications, railway rolling stock, power grid substations, elevator traction and precision instrumentation.

Internal circuitry relies on advanced semiconductors with multiple harmonic filtering stages, reinforced galvanic isolation and electromagnetic shielding.

Rigid metal enclosures deliver superior thermal dissipation and vibration tolerance under continuous twenty-four-hour operation across harsh manufacturing environments.

Technical parameters of Winsun Power AC/DC switching power converters

The portfolio of Winsun Power AC/DC converters spans electrical output ratings from 2 W up to 3 kW in single-output and multi-output form factors.

The WS700, WS650, WS360, WS250, WS80 and WS65 series are engineered for wide alternating input voltage windows, preventing automation resets during power grid sags.

Direct-current voltage stabilization provides low ripple and rapid dynamic recovery during sudden load variations.

Internal protective features encompass output short-circuit suppression, input surge absorption, line overload restriction and thermal shutdown of power switches under abnormal temperature rise.

Isolated DC/DC converters and voltage bus stabilization for automation

Galvanically isolated DC/DC converters by Winsun match intermediate voltage levels across programmable controllers, sensor networks and interface modules.

Units provide electrical isolation up to 1500 V between input and output ports, eliminating common-mode electrical noise generated by heavy motor drives.

Compact module profiles permit direct through-hole mounting on circuit boards or installation onto standard metal equipment rails within electrical enclosures. Superior energy conversion efficiency curtails internal heat dissipation and enables dependable operation in dense control cabinets.

Dedicated power units for railway transit and telecommunication networks

For rolling rail equipment, wayside signaling systems and cellular base stations, Winsun Power produces dedicated switching units including WS700-1AAC, WS250-1FAC and WS78-1BAC.

Assemblies undergo rigorous laboratory testing against repetitive multi-axis vibration, mechanical shocks and thermal variations.

Printed circuit boards feature protective conformal coating preventing surface leakage currents and copper corrosion under condensed humidity. Integrated electromagnetic compatibility filters attenuate radio-frequency emissions in full accordance with strict rail and telecom engineering norms.

Standby UPS power modules and ZUPS uninterruptible backup assemblies

For unmanned automation cubicles, elevator dispatch controllers and perimeter surveillance racks, Winsun engineered the WS20-1BAC-ZUPS standby unit. The equipment combines a regulated switching converter, an intelligent battery charger and a rapid line-monitoring transfer circuit.

During sudden utility mains blackouts, transfer to standby storage battery operation occurs within fractions of a millisecond without bus voltage dips. Built-in relay contacts output discrete alarm telemetry indicating utility power failure and battery discharge thresholds to supervisory systems.

Unit selection and supply standards for Winsun / Shanghai Winsun Power

Qualified matching of Winsun / Shanghai Winsun Power switching units, direct-current converters and spare modules is conducted using factory nameplates, part codes or technical customer requirements.

Engineers cross-reference power capacity, input tolerances, ingress protection and mechanical mounting styles.

Quotation packages specify international export terms, destination delivery schedules and full technical documentation for commissioning. Fast transportation is coordinated via experienced logistics networks to ensure safe delivery directly to your industrial production site.
