Frequency Three Phase Inverter Drives for Water Pumps in Sea Food
A pumps system controls sea water cycle in a sea food farming
plant. The water from the sea is filtered via several tanks and at
the end to the tank where sea animals live. The pumps become an
important part of this system, water flow is controlled anytime.
- Maintain positive pressure in the tanks.
- Maintain a high quality filtering system at all times.
- Avoid mechanical resonance in the surrounding equipment.
- Automatic restart at the power instant off case.
- Features of P5 series matching sea food farming pumps
Dual digital tube
Double lines of LED display, monitoring 2 kinds of information
meantime, like frequency, current, voltage, speed and PID data.
Instant power off continue running and speed tracking
Independent cooling channel design
Independent cooling channel design. This is good for applications
like printing, textile, cement and steel factories where severe

A variable-frequency drive (VFD) is a system for controlling the
rotational speed of an alternating current (AC) electric motor by
controlling the frequency of the electrical power supplied to the
motor. A variable frequency drive is a specific type of
adjustable-speed drive. Variable-frequency drives are also known as
adjustable-frequency drives (AFD), variable-speed drives (VSD), AC
drives, microdrives or inverter drives. Since the voltage is varied
along with frequency, these are sometimes also called VVVF
(variable voltage variable frequency) drives.
