Synchronous frequency inverter VH1 series

asynchronousvector controldigital

Product overview
VH1 series is an open-loop vector frequency converter launched by XINJE for low-power applications. It offers compact dimensions, high EMC compliance and a high protection rating. It is suitable for small automation machines, including woodworking roller coating, food and beverage equipment, packaging machinery, logistics conveyor lines, photovoltaic systems, fans and water pumps.

Key features

• Compact design: optimal power density to minimize product volume; supports seamless parallel installation in minimal space (ambient temperature below 40°C).
• Integrated and versatile: supports VF and SVC control algorithms; ARM-based platform; synchronous and asynchronous motor control (synchronous operation supported from 2.2 kW).
• Heavy-load output: standard IGBT module enabling 150% overload for 1 minute; integrated standard braking function for controlled stops.
• Easy and fast setup: potentiometer-type adjustable knob for simple speed tuning.
• External LCD panel support: one-click parameter upload/download via optional external LCD panel.
• PC software support: on-site debugging and monitoring via upper computer software; configurable 5-channel NPN/PNP digital inputs.
• High-spec EMC design: built-in RFI filter to reduce electromagnetic interference and meet precision control requirements.
• Thermal and reliability design: independent air duct for effective heat dissipation; full PCB conformal coating to resist oil and moisture.
• Multiple installation options and EU CE certification.
