UID40 L requires 384 V DC, which is achieved by connecting 32 12V batteries in series.The Kstar UID40 L series UPS are three-phase transformer-based systems designed to adapt to challenging environmental conditions and devices with high inrush currents, such as motor-driven or compressor-equipped machinery. The transformer provides robust protection by fully isolating the input and output power circuits, blocking voltage spikes, suppressing high-frequency harmonics andprotects the internal system from backfeed (reverse current).External batteries with a capacity of up to 200 amps can be connected to these UPS systems, ensuring extended autonomous operation of the devices.Used for specific and sensitive inductive devices such as refrigerators, air conditioners, industrial equipment, medical devices, and more.In battery mode, the UID40 L requires 32 units of 12V batteries.Functional CapabilitiesDouble ConversionPure Sine WaveGalvanic IsolationZero Transfer Time to Backup PowerInterfac...
