Frequency inverters


Variable frequency drives provide infinitely variable speed control. Typically, they are used to control AC fans or pumps in HVAC applications. These frequency inverters can control various motor types: single phase AC motors, IE2, IE3 and IE4 induction motors, AC permanent magnet motors, brushless DC motors, synchronous reluctance motors, etc. They use IGBT technology to vary both motor voltage and frequency via pulse width modulation. This results in a very precise and efficient motor control. Thanks to the integrated macros, configuration remains easy. Pump mode makes energy efficient pump control possible. Fan mode (incl. fire operation) makes air handling a breeze, ideal for simple HVAC systems.

Speed control for single phase motors - 230 VAC supply

Speed control for single phase motors - 230 VAC supply
Frequency inverters with single phase 230 VAC power supply. They control single phase 230 VAC motors. Following motor types can be controlled: Permanent Split Magnet or PSC motors and shaded-pole motors. All VFD's have built in PI control, EMC filter class C1, brake chopper and Modbus RTU. They are available in IP20 or IP66 enclosure. The IP20 VFDs are designed for indoor mounting, preferably in a cool, dry and enclosed environment such as an electrical cabinet. The IP66 VFDs are designed for harsh environments or direct machine mounting. Dust tight and ready for washdown duty.
