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.
