Variable Frequency Drives
Relec Electronics supplies variable frequency drives for applications requiring controlled ac output from a high-voltage ac or DC source. These 3.3 kVA units support 400–480 Vac or 600 Vdc inputs, with 230 Vac and 400 Vac output options.
Designed for industrial, railway, automotive, laboratory and instrumentation systems, the range uses a compact slotted-chassis format with controlled forced-air cooling. The drives support applications where output frequency and voltage must be managed to control compatible motors or other ac equipment. Railway-compliant models meet EN 50155, EN 45545-2 and EN 62368-1.
Our engineers can help confirm the input supply, output voltage, frequency range, load characteristics, cooling requirements and relevant approvals. Browse the range or contact Relec for technical selection and integration support.
