High Frequency UPS (DTH31 Series)
UPS is an electrical protection device featuring an energy storage unit with an inverter as its core component. It is capable of supplying continuous, stable and pure alternating current to loads when abnormal mains power conditions occur – such as power outages, undervoltage, overvoltage, surges and harmonic interference – thus protecting critical equipment from power-related disruptions.
Application:LAN server, communication base station, data center, finance system branch, automation control system, etc.
