The new EVAR inverters represent the next generation of frequency converters for the control of single-phase/three-phase electric pumps. They can be used in single or multiple pressurisation systems. The user-friendly graphic interface ensures easy and intuitive use of the device both during programming and normal operation.
WHAT IS AN INVERTER?
It is an electronic input/output device capable of modulating an alternating current and varying its amplitude and frequency parameters.
HOW DOES IT WORK?
By modulating the output current, the inverters make it possible to maintain constant pressure in the system. The inverter controls single-phase/three-phase electric pumps and can be used in single or multiple pressurisation systems.
HOW IS IT INSTALLED?
The wiring is extremely easy in both the installations available.
Mounting on motor terminal block: use of spring-loaded terminals.
Wall-mounted version: use of pre-wired cables.
The programming was designed in an easy and intuitive way directly on the first home screen, visible on an LCD display with a graphic user friendly interface, entering the parameters necessary for commissioning.
THE ADVANTAGES OF AN INVERTER
- Energy savings due to the modulation of electricity consumption according to the actual water consumption of the pump
- Constant pressure
- Absence of sudden pressure jumps in the system, therefore, longer life of the pump
- Reduced costs of routine maintenance
- Increased quietness
NEXT GENERATION, SALIENT FEATURES:
The next generation of INVERTERS from the EVAR line has introduced many improvements compared to the previous range, combining design, mechanical and electronic technology of the latest generation, giving great importance to the usability of the product itself. The inverter is equipped with a graphic display panel integrated on the cover.
The motor can be adjusted at the installation site for all possible configurable functions.
This version makes it possible to view the parameters on the display, indicates the presence of errors and makes it possible to change the programming by changing the configuration parameters of the inverter.
Our range of EVAR Inverters includes sizes from 0.37 kW to 5.5kW, single-phase and three-phase, with mounting on the motor terminal block or on the wall.
Designed to allow the speed variation of single-phase and three-phase asynchronous motors of any polarity, they are present inside a die-cast aluminium container and are controlled with both analog and digital inputs, FIELDBUS with Modbus protocol.
The new electronics have been designed to meet the most stringent requirements in terms of efficiency, reliability and robustness, thanks to an architecture that has already been tested for a long time. Due to the intrinsic characteristics of the product, our inverters make it possible to maintain constant pressure in the system, with a consequent energy savings due to the modulation of the electricity consumption according to the actual water consumption of the pump. The new compact and robust design characterises the new EVAR range, completely made in Italy.
