YDC3340 H requires 192 V DC, which is achieved by connecting 16 12V batteries in series.The GP810 H series UPS are single-phase transformer-based systems specifically designed to adapt to challenging environmental conditions and devices with high inrush currents, such as motor-driven or compressor-equipped equipment. The transformer provides robust protection, fully isolating input and output power circuits, blocking voltage spikes, suppressing high-frequency harmonics and And it protects the internal system from backfeed (reverse current). External batteries with a capacity of up to 200 AH can be connected to these UPS systems, ensuring extended autonomous operation for connected devices.Used for specific and sensitive inductive devices such as refrigerators, air conditioners, industrial equipment, medical devices, and more.Functional CapabilitiesDouble ConversionPure Sine WaveGalvanic IsolationZero Transfer Time to Backup PowerInterface: EPO, RS232, SNMP/Dry Contact SlotGenerator ...
