The EM700 series frequency converter is a high-reliability, small-sized general-purpose frequency converter launched by Sine Electric: EM700 supports three-phase AC asynchronous machines.
EM700 series frequency converter have the following features:
• Compact size, supports side-by-side installation;
• Pluggable main power terminals for quick installation and maintenance
• 50ºC ambient temperature, no need to derate;
• Support digital potentiometer speed adjustment, fast and accurate speed adjustment;
• Complete protection functions: multiple protections such as short circuit, overcurrent, overvoltage, overload, and overheating.
