VFD-A Series

This series is the first generation of AC motor drive with abundant features, including multi-function I/O terminal, V/f control and auto-torque/auto-slip compensation, built-in RS-485 serial interface (MODBUS) and digital keypad that can be connected to VFD with extended wire. Now it has been updated to B and M series.

AFE2000

Energy saving with AC/DC dual power flow control and corrects power factor up to 99%. Replaces traditional braking resistor for cost savings, space savings, and energy savings. PWM control substantially reduces peak of harmonic current wave and forms perfect sine wave current. IEEE STD.519–1992 standard for harmonic current distortation of less than 5%. Constant DC bus voltage that is not influenced by mains voltage fluctuation. Supports multiple DC bus intallation:

REG2000 Series (Hybrid Servo)

A traditional drive system used for inertia load work generally performs rapid deceleration, braking and positioning. When its motor is in generator mode it produces large amounts of regenerative energy that must be consumed to maintain a stable DC bus voltage and safe operation. The traditional method to solve the regenerative energy problem is to install a brake resistor. While it is easy to install and is low cost, it takes up a large amount of space and requires installing additional devices to dissipate the heat. This method provides limited efficiency and wastes the regenerative energy. Delta's REG2000 series is capable of collecting and converting your system's regenerative energy into reusable electricity for the ultimate in energy savings. The installation process is as simple as installing a brake resistor, but with only half the size and better efficiency. The REG2000 is your best green energy solution for power regeneration.

VFD-VL Series
