IP55 Explosion Proof Vector VFD AC Frequency Drive For Water Pumps

ZFeng 900 Series 5.5Kw-T General Vector Variable Frequency Drive

ZF900 is a new generation main model independently developed by ZFeng, which can adjust the speed of synchronous or asynchronous motors and has a wide power range of 5.5KW~800KW. While maintaining excellent basic performance and functionality, the product has significantly improved usability, maintainability, reduced installation space, and higher design standards from the user's perspective. It adopts a high standard design in the industry, based on years of accumulated experience in multiple industries and persistent pursuit and leadership of drive technology. With high-performance current vector technology, induction motors can be easily driven to meet the working requirements in various environments.

Function characteristics

• Multi interface mode:5 digital input terminals, one of which supports high-speed pulse input up to 100kHz; 2 analog input terminals, 1 only supports 0~10V voltage input, and 1 supports 0~10V voltage input or 0~20mA current input; Expandable with 8 digital input terminals;
• Built in sensor auxiliary power supply: 10V, 24V auxiliary standard power supply, convenient for the needs of sensors with different voltage levels.
• Supports multiple PG cards: Supports various encoder interfaces such as collector signal,splitter signal and rotary signal, easy to achieve closed-loop vector control.
• Independent air duct design: Adopting an independent air duct design can effectively prevent dust from entering the interior of the frequency converter and which can cause the faults such as short circuits, improving the reliability of the product; Choose a cooling fan with long lifespan and high air volume to effectively reduce the temperature rise of the frequency converter and ensure its reliable and stable operation.

Application 

Covering industrial scenarios that require precise control of motor speed and torque:

• Traditional industries: fans, water pumps, compressors, conveyor belts (energy-saving and consumption reducing), metallurgical rolling mills (high-precision control).
• Specialized equipment: CNC machine tools (tool feed control), textile machinery (yarn winding stability), woodworking machinery (cutting and polishing process optimization).
• Emerging fields: New energy vehicle drive motors (torque dynamic regulation), photovoltaic inverters (improvement of new energy grid connection efficiency).

Key parameters for selection

• Power matching: It is recommended that the power of the frequency converter be 1.1-1.5 times the rated power of the motor, with an overload margin reserved.
• Load characteristics: Constant torque loads (such as cranes) require low-frequency high torque output, while variable torque loads (such as fans) focus on energy conservation.
• Environmental adaptability: Ex d/Ex e certified models are required for explosion-proof scenarios, and IP55 or above protection level is required for humid environments.
