Hitachi Industrial Equipment Systems High-Frequency Inverter SJH700 (400V Class)
Hitachi Industrial Equipment Systems
400V class, supports up to 2,000Hz, high-frequency inverter with a design life of 10 years.
High-frequency inverter equipped with various functions - Maximum frequency expanded to 2,000Hz - Designed for a lifespan of 10 years with long-life fans and capacitors Machines requiring high-speed rotation - High-speed frequency expanded to 2,000Hz for machine tools and processing machines that demand high-speed rotation - Rotational speed of 120,000 min-1 (for a 2-pole motor) Customization possible with program operation function - Simplifies upper controllers and peripheral circuits, contributing to space-saving and cost reduction in control panels. Functions - Relay circuit (self-holding), timer circuit - Repetitive operation (automatic operation) - Parameter changes for the inverter based on operating conditions (multiple settings for acceleration and deceleration times, etc.) Achieves a design lifespan of 10 years with long-life fans and capacitors - An inverter that can be used more safely and for a longer time. - Components with a limited lifespan (cooling fan, electrolytic capacitor) are designed for a lifespan of 10 years. Compact design for space-saving - Built-in EMC noise filter (excluding 8kVA) Enhanced network compatibility - Standard equipped with RS-485 Modbus-RTU compatible port. Equipped with various functions - Enhanced monitoring functions (maintenance warning signals)
