American Control Electronics Microprocessor-based VFD

The ACF series open-chassis microprocessor-based variable frequency drive (VFD) is designed to offer the simplicity of a dc drive and quick and easy setup without any programming. The drive is equipped with user-adjustable trim pots to set max/min speeds, slip comp, boost, torque limit and accel and decel/injection braking parameters. The 115-/230-V single-phase input can provide single- or three-phase outputs of 115 or 230 V, making it suitable for sub-fractional hp motors and gear motors. An onboard microprocessor allows custom programming for a variety of OEM applications. Other features include adjustable base frequency and protection against overheating as a result of frequent overload.
