Frequency converter Delta VFD015B43A

Buy a Delta VFD015B43A frequency converter for accurate and reliable control of asynchronous motors

Delta VFD015B43A is a universal frequency converter of the VFD‑B series from Delta Electronics. It is designed to control the rotation speed of three-phase asynchronous motors with a power of 1.5 kW. The device supports vector and scalar control, providing high starting torque and stable operation under varying loads. This is a reliable solution for pumps, fans, conveyors and other industrial equipment.

• Vector control provides high torque at low speeds.
• Wide output frequency range from 0 to 400 Hz (up to 2000 Hz optional).
• Overload capacity 150% within a minute and 200% within 2 seconds.
• Built-in PID controller and 16 fixed speeds for flexible automation.
• Reliable design with varnished boards and built-in DC choke.

How does a frequency converter work?

The device converts a three-phase input voltage of 380–480 V into an adjustable output voltage and frequency. This allows you to smoothly change the engine speed without mechanical losses. The microprocessor with 16-bit architecture and PWM control provides speed accuracy of ±0.5% without feedback and ±0.02% with an encoder. The built-in PID controller automatically maintains the set process parameters. Control is carried out through discrete and analog inputs, as well as through the RS‑485 interface with the Modbus protocol.

Technical characteristics and functionality

Model VFD015B43A has a power rating of 1.5 kW and an output current of 4.2 A. The output frequency is adjustable from 0.1 to 400 Hz in 0.1 Hz steps. Three control modes are available: scalar V/f, sensorless vector and vector with speed feedback. The device is equipped with 11 discrete inputs, 3 analog inputs, relay and transistor outputs.
