Model Number: SBW-80KVA Brand Name: CONPO Key Specifications/Special Features: 1. Features:This series large power voltage stabilizer is an energy-saving new product developed by our company by absorbing advanced technology of Western EuropeProvided with two systems of manual or automatic dual control, direct output and stabilizing output with functions of over/under-voltage protection, delay and error protectionReliable and suitable for any load2. Applications:
Used in place with large electricity demands such as factories, post and communication, schools, hotel,acted as whole voltage-stabilizingor single voltage-stabilizing

3. Specifications:
