Advanced technology-
             Maximum Efficiency

For advanced, precision fan and pump applications to optimize energy saving. The VF-PS1 is derived from VF-AS1, with specialized HVAC, fan and pump features added. A wide range of communication protocol is also available. Applicable motor output  ranges up to 630kW, the VF-PS1 is the ultimate solution to your HVAC system.

• The efficiency of motors normally fall at light load, low speed. The advanced energy saving mode further minimize the loss of induction motor by controlling excitation current that belongs to the load. Fan and pump efficiency increases even in low speed.

• Compact and space-saving DC reactor is built-in for 200 V class 11 to 45 kW and 400 V 18.5 to 75 kW models. In addition to reducing harmonics, this reactor limits the input current to 110% of the rated output current, and it has been designed to be compatible with power supply systems containing transformers, molded-case circuit breakers, and power lines. Optional DC reactor meets IEC harmonics standards.

• High-frequency noise is drastically reduced on models with built-in noise filters. Built-in noise filters are ideal for office, commercial facilities, and factories where special attention for peripheral devices are needed. Compared with existing model, less space and wiring are realized by incorporating filter in the panel. In addition, models with built-in EMC noise filter comply with the European EMC Directive as individual inverter units.

• The expected replacement cycle of main circuit capacitors, capacitors on control board, and cooling fan are monitored. Alarm is raise when the cycle is reached to the expected replacement time.

• Fire control maintain operation at specified speeds even if certain fault occurs.

• Sleep function (Automatic stop function) further reduces the energy consumption by stopping at lower limit setting.
  

• Low torque detection function can detect a broken belt of AHU or low load to avoid pump troubles.

• PTC thermistor input can protect motor from overheating using the signal from the motor's built-in PTC.

• Quickly switch between Local and Remote control by EASY key. By switching from remote to Local (Bumpless Function), the operating frequency and status are shifted to Local mode which becomes easier for operation and adjustment.
  
• Temperature based cooling fan switches On/Off automatically, reducing noise, saving energy, and extending the cooling fan's life.

• Real time energy saved, power consumption can be easily monitored with the operating panel or through serial communication.

• Compliance with global standards including CE, CSA, UL, C-tick, GOST, NOM117
