Key Features & Advantages
1. Advanced Dual Conversion Design
- True online UPS architecture completely isolates the load from mains disturbances and generator fluctuations.
- Delivers pure sine-wave output with low distortion and high precision for industrial-grade applications.
2. Superior Load & Environmental Adaptability
- Wide input voltage (90–300V) and frequency range for reliable operation in unstable power environments.
- Strong overload and short-circuit capacity ensures uninterrupted performance under extreme load conditions.
- Intelligent fan speed control automatically adjusts cooling based on internal temperature and load, reducing noise and extending fan life.
3. Comprehensive Protection System
- Built-in power-on self-diagnosis and complete multi-layer protection, including:
- overload, short-circuit, inverter over-temperature, battery overcharge/undervoltage, and surge protection.
- Dual software + hardware protection guarantees long-term system safety and reliability.

Why Choose KESUN UPS Systems?
With decades of manufacturing expertise, KESUN delivers industrial-grade online uninterruptible power supply UPS systems trusted worldwide. Our UPS solutions integrate advanced DSP technology, global safety standards, and customized OEM/ODM services, providing power protection you can rely on — anywhere, anytime
Our UPS Workshop
Our 13,000 ㎡ voltage stabilizer workshop runs 25 production lines, supported by a mold center, product testing lab, and dedicated workshops for winding, assembly, sheet metal work, and aging tests. With 200 team members, including 32 technical engineers, we produce over 1,000 voltage stabilizers daily.
Quality Control
- Every voltage stabilizer undergoes a 100% routine inspection before shipment:
Visual & mechanical check → Safety tests (insulation, dielectric strength, earth continuity) → Regulation performance test at no-load / half-load / full-load → Protection function verification (OV/UV/overload/short-circuit/over-temperature) → Full-load aging test → Noise & display check → Final inspection, record filing & packaging. - Max voltage regulation accuracy: ±1%, THD ≤3%, full-load efficiency ≥95%.
- Our products meet IEC standards with CE & RoHS certifications.














Packing & Shipment
- Voltage stabilizers come in shockproof, moisture-proof, and rust-proof export packaging. Small units use reinforced cartons; large industrial models adopt IPPC heat-treated wooden crates or pallets. Machines include corner buffers, insulated terminals, and desiccants to prevent condensation and corrosion. Outer boxes are marked with Fragile, This Side Up, Keep Dry, and clear shipping marks.
- Air Freight: Complies with IATA rules. Terminals are insulated, and loose metal parts are secured.
- Sea Freight: Enhanced protection against salt spray. Solid wood packaging must carry valid IPPC marks to avoid quarantine detention.
