Description
MIDA AC Overview
Next generation of solar pumping inverter. Ideal for any kind of solar pumping application
Allows:
- Energy saving due to variable speed control.
- Soft start and soft stop.
- Extended system life and reliability.
- Installation on humid and dusty environments made possible by IP55 (NEMA 4) protection degree.
- Simplified installation on motor or wall.
- Easy and fast commissioning thanks to initial configuration wizard.
- High thermal and mechanical performance thanks to aluminium case and independent ventilation.
Extended system life and reliability.
The average speed of a pump driven by MIDA is inevitably lower than a comparable fixed speed pump. This reduces component wear such as bearings, bushings, seals, etc. MIDA also starts and stops the pump gently, reducing the mechanical stress on the shaft and impellers and avoiding water hammer. Hardware and software protections provided by MIDA prevent any damage to the pump and the system. At lower speeds, the system will also generate less noise.
Energy saving due to variable speed control.
The power consumed by the pump is proportional to the cube of its speed. Unlike traditional systems where the pump speed is fixed and controlled by the mains frequency (@ 50 Hz, about 3000 rpm), MIDA is able to vary the pump speed according to water demand. In the presence of low demand, MIDA controls the pump at a reduced speed, which consumes less power. For example, if the pump turns at 40 Hz (about 2400 rpm) instead the nominal 50 Hz (about 3000 rpm), power consumption would be half.
Complete pump protection
Built-in protections against:
- Overvoltage and undervoltage.
- Overcurrent and no load.
- Dry running.
- Overtemperature.
Design
High thermal and mechanical performance thanks to aluminium case and independent ventilation.
Installation on humid and dusty environments made possible by IP55 (NEMA 4) protection degree.
Simplified installation on motor or wall.
Motor on-board installation
Wall fixing
MIDA is cooled by an its dedicated cooling fan and it can be mounted to the wall through the use of 4 scews.
EMC compatibility for residential environment on single phase models
- Integrated PFC (P.F. 1) to meet EN61000-3-2
- Integrated input filter for Category C1 (EN61800-3), Class B (EN55011)
