TOSHIBA Toshiba VFAS3-4037PC-F frequency converter

TOSHIBA Toshiba VFAS3-4037PC-F frequency converterVF-AS3 can drive motors for multiple water pumps (up to 10 pumps can be controlled), and can achieve the goal of saving overall power of the water pump system and significantly reducing costs by appropriately controlling a single water pump.

Each water pump can be connected to a commercial power source by using a relay output signal from a frequency converter to control an electromagnetic contactor.

This frequency converter has three relay output terminals. In addition, two input/output expansion boards can be inserted into the frequency converter. Due to each input/output expansion board having 3 relay output terminals, a maximum of 9 relay output terminals are available for use.

Save space and reduce costs through embedded proportional integral derivative (PID) controllers

VF-AS3 has four built-in PID controllers: two for frequency converters (motors) and the other two for other devices, including heaters and valves. This built-in PID controller can meet the needs of multiple applications simultaneously. Due to the fact that this design does not require an external PID controller, it helps to reduce costs and minimize the required space.

The functions of this PID controller include temperature or pressure control of fans and water pumps, speed control of winding machines, and control of stop positions.

Applications in the chemical/pharmaceutical industry

Pump/Blender/Compressor/Centrifuge/Fan

·This frequency converter can operate at ambient temperatures ranging from -15 to+60 degrees Celsius.

·The smooth aluminum electrolytic capacitors for cooling fans, power circuits, and control circuits have a design life expectancy of up to 10 years.

Multi in one design. Enhance availability

TOSHIBA Toshiba VFAS3-4037PC-F frequency converterVF-AS3 supports various functions without the need for external optional accessories.

VF-AS3 enhances availability and reduces costs.

No need to prepare separate optional equipment.

Reliable security features

VF-AS3 has a safety torque cutoff (STO) function as a standard configuration, which can reliably shut off the output in emergency situations.

This safety torque shutdown function can safely switch mechanical equipment to a torque free state to prevent accidental start-up.

This function meets the requirements of the safety standard IEC61800-5-2, and the safety integrity level has reached the SIL3 safety level specified in the standard IEC61508:2010.
