What brand of frequency converter is frenic?
Fuji frequency converter FRENIC-VP is a frequency conversion device launched byJapanese Fuji Electric Co., Ltd..
Fuji inverter FRENIC-VP series has the best functions required by the HVAC (Heat Ventilation Air Conditionar) industry, including space saving, easy operation, rich models, and global support. Give full play to the load characteristics of fans, water pumps, and quadratic decreasing torque to save energy and labor, fully tap the system's adaptability, and meet the needs of overall cost reduction.
Equipped with functions suitable for HVAC applications
1. Power frequency/inverter switching
Loaded with external timing sequence corresponding to the inverter power frequency starting process when switching between power frequency/inverter . There are two built-in power frequency operation switching timing sequences: Fuji standard timing sequence and automatic power frequency switching timing sequence when the inverter alarms.
2. Reprinted complete PID control function
The PID regulator that controls operating temperature, pressure, flow, etc. is added with "low water volume stop function" and "deviation alarm and absolute value alarm output" ". It also makes it easier to adjust the PID control function through the anti-reset termination function to prevent PID control overshoot, the PID output limiter, and the integral hold/reset signal.
3. Restart after instantaneous power outage
When the power supply is restored after an instantaneous power outage, it can automatically restart. You can choose to start from the frequency where a momentary power outage occurs or from 0Hz. When a momentary power outage occurs, you can also choose a mode that uses the motion energy with load inertia to reduce the frequency and continue operation.
4. The inverter remote/panel control mode switching can be realized
By switching frequency setting 1/frequency setting 2, run/stop command 1/run/stop command 2 and local operation (Operation panel operation), not only can switch the operation command and frequency command, but also can switch the remote/panel control mode.
5. A variety of frequency setting methods can be realized.
Can be used in conjunction with the frequency setting signal to select the most appropriate frequency setting method. Operation panel operation ↑↓ keys, analog input (4-20mA, 0-5V, 0-10V, 1-5V, forward/reverse action), multi-step frequency 8-step (0-7 segments) setting, UP/ DOWN, communication and other methods.
6. The introduction of the motor during the idling process allows the motor to start smoothly by detecting the operating frequency even when natural convection causes the motor to idling.
7. The lower limit limiter realizes sleep function
The lower limit limiter of the minimum operating speed of fans, water pumps, etc. is added with the function of stopping below the lower limit value, which can also be used as a low water volume Stop feature usage.
