>In 2021, the state issued new standards for motor energy efficiency, requiring the minimum energy efficiency of motors to be IE3. In order to meet this standard,
most domestic water pump manufacturers are currently trying to apply permanent magnet synchronous motors or synchronous reluctance motors in water pumps.
Based on this requirement, our company has developed the P730 series of backpack type water pump inverters.
>P730 water pump frequency converter supports vector control of permanent magnet synchronous motor and synchronous reluctance motor, adopts motor piggyback installation,
IP55 protection level, fully meets the requirements of the working environment of water pumps. This series of products is 1.5KW~22KW,
which can cover most of the needs of water pump applications (currently, our company can provide two specifications of 5.5KW and 7.5KW).
Function | EM760 | Remark |
lock water pump 1 | F51.10 | Through the function code setting, lock the corresponding pump 0: Not locked 1: Locked water pump, factory default 0 |
lock water pump 2 | F51.11 | |
lock water pump 3 | F51.12 | |
lock water pump 4 | F51.13 | |
lock water pump 5 | F51.14 | |
lock water pump 6 | F51.15 | |
lock water pump 7 | F51.16 | |
Water shortage protection function | F51.18 | 0: off (factory default) 1: open, judged by outlet pressure 2: Open, judged by frequency and current |
Water shortage protection threshold value | F51.19 | When the feedback water outlet pressure is less than the water shortage protection detection threshold and remains beyond the water shortage protection detection time, it will report water shortage protection, E59 water shortage protection |
Water shortage protection detection time | F51.20 | |
Water shortage protection detection frequency | F51.21 | When the output frequency > water shortage protection detection frequency, start to judge whether there is water shortage, and the output current < the set water shortage protection detection current (percentage relative to the rated current of the motor), and keep exceeding the water shortage protection detection time, then report water shortage Protect |
Easy to install:
This series of inverters can be easily installed on the motor. It is not necessary to change the appearance of the motor in order to cooperate with the installation.
Just add a base plate according to the installation size, install the inverter on the base plate, and then fix the base plate on the motor. .
The external structure of the inverter is shown in the figure below.
P730 series installation dimensions
Specification | W | W1 | H | H1 | H2 | D | D1 | d |
P730-5R5-3B | 175 | 155 | 278 | 198.5 | 250 | 116 | 53.5 | 5.5 |
High protection level:
In order to meet the challenge of the high-humidity environment of the water pump,
the circuit boards of this series of inverters have been treated with three protections,
and waterproof connectors are used for the inlet and outlet ports. The protection level of the whole machine is IP55.
Low noise:
In the water supply industry, especially secondary water supply residences have high noise requirements,
high carrier frequency can greatly reduce motor noise, and the carrier frequency of P730 can reach up to 10KHz. After testing,
the P730 series inverter is equipped with a synchronous reluctance motor, the overall noise can be reduced by more than 5dB compared with the asynchronous motor,
and the maximum noise does not exceed 63dB.
Various peripheral interfaces:
a) This machine comes with LCD display panel
b) 5-way DI input, 1-way DO output, 1-way relay output
c) 2 analog inputs (one of which supports 0~10V, one supports 0-10V or 0-20mA)
d) One analog output (support 0-10V or 0-20mA)
e) Support MODBUS-RTU communication.
