Toshiba VFAS3-4055PC-F inverter from Japan

Toshiba VFAS3-4055PC-F inverter from JapanVF-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

Better environmental resistance performance

Complies with the relevant requirements for chemicals (3C3)/dust (3S3) in IEC60721-3-3 standard. (A6 type outline drawing or smaller specifications)

·It can be used at an altitude of up to 4800 meters. (A6 type outline drawing or smaller specifications)

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

Multi in one design. Enhance availability

VF-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.

Toshiba VFAS3-4055PC-F inverter from JapanReliable 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.

VF-AS3 has good compatibility with power systems and peripheral devices. The built-in dual DC reactors have the function of suppressing harmonic currents and improving power factor.

VF-AS3 complies with the IEC61000-3-12 standard, and its total harmonic distortion (THDi) can reach a level of less than or equal to 48% without external reactors. (Limited to 480V voltage level only)

High frequency noise reduction

The built-in electromagnetic compatibility (EMC) filter can effectively suppress high-frequency noise. This filter is suitable for commercial facilities, offices, factories, and other places that require attention to peripheral devices.
