Chapter II Overview
2.1 Introduction
RTI sine wave inverter series is especially designed and produced for the enterprises in electrical power
system and post and telecommunication industries according to their actual requirements under the
condition of not only considering the spatial installation size and the automation and networking
requirements for the inverter management in IT age, but also considering the influence of the noise on
the personnel in oces or in machine rooms.
The inverter of this series employs advanced SPWM and CPU control technology to realize precise
control, isolated input and output, output soft start, safety and high eciency, good reliability and strong
impact resistance to inductive load. Not only with small volume, light weight, beautiful appearance,
convenient installation and maintenance, simple operation, low noise, low backward noise and no
pollution, but also with the function of real-time data collection and multi-path remote communication,
the products of this series can provide convenience for many system users to implement network
management and remote control.
Meanwhile, RTI series is not only applicable to the communication industry, but also applicable to other
occasions with high requirements for power supply quality, thus becoming the ideal selection of the
power supply for oce automation.
2.2 Functions and features
●RTI series refers to the intelligent dedicated REKOSER RTI series inverter and employs intelligent
microcomputer CPU control technology and advanced control theory as well as mature and stable
high-frequency inversion mode in order to rapidly respond to the external environment change
and constantly provide high-quality AC output in a real-time manner.
●RTI series employs advanced PWM+SPWM pulse width modulation technology to realize output
soft start, and the output thereof is the pure sine wave with stable frequency and voltage, filtered
noise and low distortion factor.
●Dierent from other false isolation modes, the advanced DC-AC electric isolation technology can
really realize the completely electric isolation of DC and AC in all circuits and accordingly meet the
isolation requirements of all application systems as well as eliminate all possible mutual
interferences.
●This product has startup self-inspection function, strong loading capability and good load
compatibility; the built-in by-pass switch has improved the continuity and reliability of the
REKOSER RTI series inverter.
●This product also has direct startup function by mains and allows the users to provide power
supply to the load through the by-pass mains when there is no DC input; meanwhile, it also allows
to cut o DC under startup status and to automatically switch to the mains by-pass, without
influencing the power supply for the load while facilitating the maintenance replacement of the
storage battery.
●This product also has intelligent unattended operation function, namely: after the output is cut o
due to too high or too low DC voltage, mains failure, etc., the power supply can automatically
recover the output when the DC voltage or the mains returns to normal condition. Therefore, this
