MINI-L Series Mini Variable Frequency Drive
At its most basics, the variable frequency drive is a kind of motor controller that controls the frequency and voltage of a motor. Designed mainly to handle small power supplies, the MINI-L series variable frequency drive utilizes advanced control scheme to deliver high torque, precision, and wide-range speed control. Housed inside a compact package are a number of desirable features like the PID controller, PLC system, programmable controller input and output terminals and pulse frequency functions, which give the VFD motor control powerful functionalities.
Features of Variable Frequency Drive
1. The intelligent power module, or IPM for short, houses inside all variable frequency drive parts in a compact design.
2. Built-in PID supports automatic sleep and wake functions.
3. This inverter drive offers 7 preset speeds.
