From the cooperation between STEP and the TOP enterprises in the water industry for more than ten years, it is found that the area of agricultural irrigation is wide. In order to meet the requirements of comprehensive irrigation and energy saving and carbon reduction, only one distribution box near the vegetable field can supply power, and the motor cable of the frequency converter needs to be placed very long.
This requirement is an important feature of PD110: whip length is accessible. Its arm (inverter output cable) allows extension to a distance of 500 meters and still runs reliably. Of course, behind it is STEP's strong research and development team's continuous upgrading of algorithms, as well as the update and iteration in device selection and product design. Such a long arm means that the PD110-driven water pump has a larger irrigation radius, the travel distance of agricultural machinery and tools can be shorter, and the use of electricity and oil can be more efficient. When translated into carbon emissions, it can strongly support the emission reduction target.
How can the frequency converter itself for irrigation be afraid of water? PD110 itself is a small strong man, IP55 protection level added body, not afraid of rain, can withstand any Angle of low-pressure sputtering without influence, can also resist the general concentration of dust and insect invasion.
It's normal for farm power to be unstable. Generally, frequency converters can only deal with faults for more than 10% power grid fluctuations, that is, downtime and water supply stop. This is not friendly to the continuous production of agriculture. PD110 is good at resisting the fluctuation of the power grid. Relying on the strong bus to support the current capacity, it can also be instantaneous power loss and cross in extreme cases. So that customers do not have to go back 500 meters to restart the inverter.
Most of the civil customers have no time to learn the maintenance knowledge of frequency converter, to study the meaning of the parameters of frequency converter, right? STEP's industry experts have their customers in mind. For most of the civil frequency converter occasions, PD110 friendly operation interface and function Settings at a glance, basic can be free of Settings, programming, debugging, that is, connect and use, fast and convenient. If there is a special application, press PD lovely face (man-machine interface), you can rely on the guidance, simple change a few numbers to complete the configuration.
The design of PD110 comprehensively considers the application scenarios of various water pumps and supports a variety of motor types commonly used in the market, including asynchronous motor, synchronous motor and synchronous reluctance motor.
PD110 inverter has the following abilities:
1. Operation mode key: support a variety of operation modes, constant pressure water supply (constant pressure mode), constant current output (constant current mode), constant speed (constant frequency mode) are not under the words, one key switch, easy to use;
2. Reverse key: motor wiring dislocation, reverse don't worry, one key switch, easy to fix;
3. Float key: automatically start and stop control according to the water level; Or by short connection, realize the call self - activated power; Mom and dad don't have to worry anymore;
4. Timing key: small PD comes with timing function, can realize timing start or stop, farmer uncle uncle busy does not matter, after the first set, to the point of automatic execution, do not have to go back and forth, is not very convenient?
In addition, according to the application scenario of the pump, but also specially designed water protection, plug protection, lack of phase protection, overload protection, etc.; Constant pressure water supply mode also has constant pressure hibernation function, turn off the tap pressure constant can hibernate, in order to achieve the effect of energy saving; The pressure sensor also has protection, can only say intimate design, comprehensive protection, you deserve!
PD110 frequency converter has the following characteristics:
1. High IP55 protection;
2. Ultra distance motor control and drive, 500m longest;
3. Ultra-wide input power supply, minimum support 250VAC, no derating above 300VAC;
4. Easy to use operation interface, multi-function convenient one-key switch: forward and reverse, float ball, timing function, constant voltage constant frequency constant current operation mode switch and so on.
The PD110 comes in different sizes, covering 0.75kW to 22kW; PD110, that is, is a clever understanding of the user's inner needs of the little naughty, but also a do not love sick cold, love spring and green small strong man.
Such products are designed for civil and agricultural use, construction sewage, sewage treatment, municipal engineering, residential areas, farmland irrigation and mining exploration and other occasions of water pump intake control
