Power Efficiency Management System for Pumps and Fans

Control operation functions:
1) Automatic energy saving operation, adjusts motor working status automatically,
    and keeps motor running with high efficiency 
2) PID closed-loop control, signal obtained by special sensor, output regulated 
    automatically
3) PLC control system formed by multi-function terminals with easy operation 
4) Frequency range: 0 - 500Hz adjustable, 16 speed intervals control 
5) Carriage frequency up to 15Hz to minimize motor noises 
6) Automatic torque compensation and automatic slip compensation

Configuration: 
1) Pulse input: 0 - 50kHz (up and down optional) 
2) Constant water supply pressure system for single pump/multi pumps 
    (additional accessories needed) 
3) RS485 standard interface
4) Analog input/output interface that is convenient for commissioning on site
5) New generation of IGBT module 
6) Inside timer and counter 
7) Two sets of power supply: 0 ~ 5V/10V and -10V ~ +10V 

Protection features:
1) Realize motor silent running 
2) Electronic thermal relay protects motor from over-current input 
3) Output grounding protection and short circuit protection ensure safe motor running
4) Self-reset and re-start function make trouble shooting on site much easier 

Inquiry function:
1) Fault types inquiry 
2) Running frequency, current, voltage, power and motor rotating speed 
    monitoring and inquiries 

Application scope: 
1) Thermal power plant: Blowing fan, draught fan, exhauster fan, circulating 
    pump, feed pump, water-supply pump and backwater pump for heat supply grid 
2) Municipal water supply and water feeding pump 
3) Petroleum: water injection pump, crude oil pump 
4) Chemical: compressor, fan, circulating water pump and ice machine 
5) Mine: mine refuse pump, ventilator, and ball milling machine 
6) Metallurgy: water-feeding pump, dust-cleaning machine, and induced draft fan 
7) Cement: water pump, induced draft fan, dust-cleaning fan, and grinding machine
8) Others: the fans and pumps are used for pharmacy, papermaking, and sewerage 
    treatment and so on
