Vectron Elektronik VC 400‑045 Frequency Inverter 

The Vectron Elektronik VC 400‑045 is a high-performance industrial frequency inverter designed to provide reliable speed and torque control for three-phase electric motors in demanding automation and drive applications. Part of the VCB 400 series, this model delivers 22 kW (≈ 30 HP) power output and supports 3-phase systems at 400 V (up to 480 V) with a rated current suitable for medium-power motor drives. It is designed for installation in electrical cabinets and industrial environments where precise motor control, energy efficiency, and smooth operation are required.

Features

Reliable Motor Control

• Provides variable frequency drive (VFD) control for 3-phase AC motors, enabling adjustable speed and acceleration/deceleration profiles for process optimization.

• Ensures smooth motor start/stop and consistent performance across varying load conditions.

Industrial-Grade Design

• Built for cabinet installation with proper ventilation to manage heat dissipation.

• Designed for continuous operation in industrial environments under specified ambient conditions.

• Requires qualified installation according to electrical safety standards.

Electrical & Thermal Performance

• Operates on a 400 V AC supply (max. 480 V) at 50–60 Hz, with a rated output current of approximately 45 A.

• Delivers nominal power around 22 kW, suitable for medium-duty industrial motor applications.

• Includes provisions for proper fuse sizing and cable selection to ensure safety and minimize electrical losses.

Installation & Safety

• Must be mounted vertically with adequate clearance for heat dissipation.

• Proper shielding and grounding practices are required to reduce interference and ensure electromagnetic compatibility.

• Only qualified technicians should perform installation and commissioning due to the risk of electrical shock.
