Product Overview:
SAFESAVE 380V SN200G type frequency converter is a high performance vector inverter for general purpose with low speed and high torque output. It's specially developed for 485 communication function of VFD-200G series frequency convertor. And this frequency inverter adopting isolation scheme, electric parameters conform to international standard and users can select based on demands so as to control operation of frequency convertor and set parameters through remote serial port.
Product Features:
1. It supports three voltage levels-single phase， 220V, three phase 220V, and three phase 380V.
2. In addition to the speed sensor vector control，sensorless vector control, V/F control, it also supports V/F separation control
3. It supports two kinds of bus-modbus-rtu and CANLINK
4. It supports differential encoder, open collector encoder, rotary transformer, etc
5. The new SVC (sensorless vector control) brings better low-speed stability, stronger low-frequency load capacity, and the support for SVC torque control.
6. The background software can achieve the frequency converter parameters of the upload, download, real-time oscilloscope and other functions.
Storage of frequency convertor
1. Put in packaging box of our company as per orignal package for storage.
2. Long-term storage will lead to detenioration of electrolytic capacitor. Ensure electrifying once for at least 5 hours within 2 years, and voltage regulator should be used to gradually increase input voltage to rated value.
Warranty
Free maintenance only suit to frequency convertor. If any fault or damage under normal use, our company is liable for maintenance for I8 months(since the date of leaving factory and barcode on machine prevails). If beyond 18 months, rational maintenance fee will be charged. Under below conditions, certain maintenance fee will be charged within 18 months: device damage caused by violating stipulations in manual; damage caused by fire, flood and abnormal voltage, etc, damage caused by using frequency convertor for abnomal functions. Related service fee will be calculated as per unified standard of manufacturer. If any contract, the contract will prevail.
