BWT-DT2000 parallel inverter specially designed to the application of reliability and cost-effective & high safety power supply. It uses full (electrical) isolation inverters technology to convert direct current into high quality pure sinusoidal alternating current (AC),Rack mount type easy install in the cabinet.
It has the advantages of simple operation, low noise, no pollution, real-time data acquisition and remote communication, provides convenience to the users of the system to implement network management and remote monitoring. The inverter is not only suitable for Power and communication field, but also suitable for other places where requirement of high quality power supply.
Feature
BWT-DT2000 series parallel inverters are the intelligent inverters. The 32-bit DSP digital control technology achieve control the line simply, reliably and quickly to respond to the changes of external environment.
BWT-DT2000 series parallel inverters adopt SPWM pulse width modulation technology and output pure sinusoidal wave with stable frequency, stable voltage, noise filtering and low distortion.
BWT-DT2000 series parallel inverters have strong carrying capacity and built-in bypass switch, which improves the continuity and reliability of power supply for inverters.
BWT-DT2000 series parallel inverters adopt advanced back-injection noise suppression technology at DC input, and do not interfere with other communication equipment sharing DC power supply. AC input adopts multiple filtering to eliminate the interference of municipal power grid and meet the demand of main AC power supply in application system.
BWT-DT2000 series parallel inverters can be flexibly set to AC main supply and DC main supply (through LCD screen field setting)
BWT-DT2000 series parallel inverter power supply when the failure of buzzer alarm, can be closed by silencing key
BWT-DT2000 series parallel inverter power supply design is perfect, allowing to cut off DC in the state of start, automatically switch to power bypass, do not affect the load of power supply, convenient to battery maintenance and replacement;
Communication mode RS485,MODBUS protocol.
