Water-Cooled and Air-Cooled Frequency Converters by RATTMMOTOR Review

【Technical Parameters】- Control Model: SPWN. Power: 2.2KW. Input:1 or 3 phase 110V 0-50Hz/60Hz. Output:3phase 110V 0-400Hz. Communication Control: RS-485. Vibration: below 0.5G. Operation Temperature: -10 ~40°C. Five-Digits Display and Status Indicator Lamp display frequency, current, revolution, voltage, counter, temperature, foward or reverse running, fault, ect. 【General Control】- In addition to 4 segment reduction time (0.1-6500 seconds) can be arbitrarily selected, not only can set a V / F curve, but also set torque, up to 10.0% start torque can reach 150%. There are also other functions, like an automatic voltage regulator (AVR), deceleration stop or free stop, DC brake, automatic reset reset, frequency tracking, PLC program control, transverse control, carrier adjustable by max 20kHz, ect. 【Input/Output Terminals】- 6 Multi-function input terminals can implement 8 speed control, program operation, 4 segment reduction switching, UP/DOWN functions, counter, external emergency stop function. There are 5 multi-function output terminals for displaying running, zero speed, counter, external abnormity, program operation and other information and warnings. 【Multi-Protection Functions】Including overload protection, FUSE broken-motor stops protection, over-voltage / low-voltage protection, restarted by frequency track after instantaneous stop, anti-stall during acceleration/deceleration operation, electronic circuit protection. And many other protection functions, such as over-heat protection, restriction of reverse running, direct start after power on, fault reset, parameter lock PID, one-drive-more, ect. 【Installation/use environment】In order to make the cooling effect, the frequency converter must be installed vertically and ensure that the air is flowing smoothly. Before installing and using the product, please read the instruction manual (included in the package) of the inverter carefully to give full play to its functions and ensure safety.
