Hitachi Industrial Equipment Systems High-Frequency Inverter SJH700 Series
Hitachi Industrial Equipment Systems
High-frequency inverter SJH700 series compatible with 2,000Hz high-speed rotation.
Features - Machines requiring high-speed rotation High frequency: Expanded to 2,000Hz, suitable for machine tools and processing machines that require high-speed rotation. Rotational speed of 120,000 min-1 (for 2-pole motor). - Customization possible with program operation function The upper controller and peripheral circuits can be simplified, contributing to space-saving and cost reduction of the control panel. Relay circuit (self-holding), timer circuit Repeated operation (automatic operation) allows for parameter changes of the inverter based on operating conditions (multiple settings for acceleration and deceleration times, etc.). - Designed for a lifespan of 10 years with long-life fans and capacitors This inverter can be used safely for a longer time. The lifespan components (cooling fan, electrolytic capacitor) are designed for a lifespan of 10 years. - Compact design for space-saving Built-in EMC noise filter (excluding 8kVA). - Network For more details, please contact us.
