ZFeng 900 Series 37Kw-T-P General Vector Variable Frequency Drive The frequency converter is the core equipment of industrial
control, which has been widely used in multiple fields. With our
company's technological innovation and industrial upgrading, our
products will further evolve towards intelligence, integration, and
green direction, helping global industrial transformation and
sustainable development. Key Features- Speed control: By adjusting the output frequency, the motor speed
can be smoothly and infinitely adjusted to meet the production
process requirements.
- Energy saving operation: Adjust the motor speed according to the
load demand, avoiding energy waste caused by traditional adjustment
methods such as baffle adjustment, and achieving significant
energy-saving effects.
- Protection function: Provides multiple protections such as
overcurrent, overvoltage, overload, short circuit, and grounding to
ensure the safe operation of equipment and motors.
- Power factor optimization: reduce reactive power loss, improve
power factor of the power grid, and reduce harmonic interference.
Working Principle- Rectification: Convert input AC power into DC power through a
rectifier bridge.
- Filtering: Filtering DC electricity through capacitors or reactors
to smooth out voltage fluctuations.
- Inverter: Using IGBT and other switching devices to invert DC power
into three-phase AC power with adjustable frequency and voltage.
- Control unit: Adjust the output frequency and voltage according to
the set parameters and requirements to achieve precise control of
the motor.
Case- Central air conditioning: By controlling the freezing pump and
cooling pump through variable frequency speed regulation, the
energy-saving effect is significant.
- Injection molding machine: controls oil pump pressure or flow rate,
saves 20% -52% electricity, replaces traditional proportional valve
throttling speed regulation.
- Steel rolling mill: realizes low-frequency load starting,
synchronous operation between frames, and constant tension control.
