With a three-phase power supply of 380–480VAC at 50/60Hz, the VLG3 series is a powerful yet easy-to-use solution for a wide range of industrial applications. From conveyor belts and textile machines to pumps, fans, and compressors, this series provides the precision and performance industries demand.
What Are Variable Speed Drives?
Variable Speed Drives (VSDs) are essential devices used to control the speed and torque of electric motors by adjusting the frequency and voltage supplied. By doing so, they offer enhanced operational efficiency, reduced energy consumption, and extended equipment lifespan. VSDs are widely used in industries where precision control and energy efficiency are critical, such as manufacturing, HVAC systems, and automation.
Introducing the VLG3 Series
The VLG3 series is a general-purpose, three-phase variable speed drive, engineered for versatility and ease of use. With power ratings ranging from 0.4 to 22 kW, 0.5 to 30HP, this new series integrates key features such as an EMC suppressor and braking chopper as standard. Its compact design supports side-by-side installation and offers flexible mounting options, including DIN rail and screw mounting.
Equipped with a front-facing keypad featuring a 7-segment LED display, a built-in potentiometer for frequency adjustments, and an RJ45 connector, the VLG3 ensures straightforward configuration and monitoring. It also includes an RS485 serial port with Modbus-RTU for seamless integration with PLCs, HMIs, and supervisory control networks. Additionally, an optional Ethernet communication module can be installed for enhanced connectivity.
Fully approved to EN/BS 61800-5-1, EN/BS 61800-3, UL 61800-5-1 & CSA C22.2 N° 274
