Commercial & Public Facilities (Shopping malls, hospitals, hotels, office buildings)
Safety, quiet operation, flexible installation. Designed for space-constrained basements and other installation scenarios with compact size (transportable via standard elevator), low noise (sound power level ≤45 dB), and fully sealed moisture-proof construction.Data Centers & Precision Manufacturing (Electronics factories, laboratories)
Low loss (energy-efficient PUE), low partial discharge (PD), dust prevention. Significantly reduces no-load loss (e.g., SCBH series achieves 70% reduction in no-load loss), helping optimize PUE; PD level ≤5 pC ensures clean power supply.New Energy & Industrial Fields (Photovoltaics, energy storage, industrial parks)
Strong overload capacity, harmonic resistance, weather resistance. Capable of withstanding 1.5x overload to handle motor starting surges; supports low-voltage side voltages up to 690V, suitable for new energy applications.Harsh Environment Applications (High altitude, high humidity, dusty conditions)
High IP protection rating, corrosion resistance, vibration resistance. Protection ratings such as IP23/IP54; moisture resistance (operable at 100% humidity) and dust resistance enabled by vacuum epoxy resin casting process.Rated Capacity(kVA)
