China Znb23 Series DC AC Inverter

Product Description
1.Description
The device is used to incorporate in the existed DC supply system to offer an AC UPS(uninterrupted power supply) for sectors of communication, measure or monitoring in systems of electrical power or communication.
2.FeaturesWorking-frequency isolation for input and output ensures a capacity of anti-interruption and short circuit.Broad application for load category from pure capacitive load to pure inductive load.The adoption of multi-control technology of instantaneous voltage out-loop and current in-loop and partial-magnetism resistance makes sure a standard sine output and good wave dynamic performance and small THD(total harmonic distortion).Trace phase and frequency of civil power grid with high-precision digital phase-locking ability.The functions of self-startup, soft-startup, self-diagnosis and self-reset in case of fault are available.The standard RS485 interface and outlet contacts are available,so the information could be delivered to upper monitoring system.Very high peak-peak coefficient that very applies in rectifying load.Explicit LED working process display.Perfect protections with audible and optical alarms.The devices could be serried-connected to work together(one could be as an online backup)
