Synchronous frequency inverter VHL series

asynchronousthree-phasesingle-phase

Product overview
The VHL series open-loop vector frequency inverter features a book-style (narrow) chassis that reduces volume by approximately 30% and installation area by around 70% versus the previous generation. It uses IGBT integrated modules and supports 150% overload output for 1 minute. The series includes a standard braking function, an independent air duct design and a strengthened three-proof coating meeting 3C3 (reference 3S2) for reliable operation. Plug-in fan design and support for an external LCD panel simplify maintenance and commissioning. CE certified.

Product features

• Overload output — IGBT integrated modules deliver 150% rated output for 1 minute; standard braking function enables controlled, extended stop of driven equipment.
• Book-style structural design — narrow chassis reduces unit volume by ~30% and installation footprint by ~70% compared with the previous generation.
• Easy and fast commissioning — flying-shuttle type keypad for straightforward speed adjustment; silicone keypad for improved tactile feedback; supports external LCD panel for one-click parameter upload/download.
• Stable and reliable — strengthened three-proof paint coating to meet environmental requirements (3C3 and referenced 3S2); independent air duct improves thermal reliability.
• Plug-in fan — removable plug-in fan for quick replacement and reduced maintenance time.
• Certification — compliant with EU CE certification.
