The SN-HH series of AC drives is a high performance AC Drive  that produces an output of adjustable voltage and frequency to control the speed of a squirrel cage induction motor for drilling. The modular design unit has separate converter capacitor inverter sections installed in a common enclosure. Sections can be paralleled to increase power. This PWM design provides high starting torque by use of IGBT transistors. The drive provides 3 modes of control and speed accuracy to suit application requirements; V/Hz (2%), sensor less vector (0.1%), or flux vector control (0.01% / motor-mounted Resolver (standard) and drive-mounted PG-RD1 card required). Programmable, networkable, and modular are outstanding features of the SN-HH series AC drive.

AC Inverter Motor Drive is the comprehensive flux vector control AC inverter. AC Inverter Motor Drive can be used in elevator, lift application. There are four control patterns: Standard V/F control, V/F control with PG feedback, Sensorless flux vector control and vector control with PG feedback. EI-Super provides the servo-like precision machinery to multiple types of motor drives. The capacity of AC Inverter Motor Drive is up to 900kW. Large power can be custom-designed in the cabinet protection.

AC Inverter is a high-performance vector control AC Drive Inverter. The frequency reference can come from built-in potentiometer, analog input reference and serial communication. The capacity can go up to 30kW. The great feature is the configurable voltage/frequency characteristics to achieve the power-saving control.

AC Drive features V/F control pattern. AC Drive has MODBUS message format and optional RS-485 communication card. The widely applied capacity ranges from 0.75kW up to 7.5kW for 220VAC and 440VAC Class. It is built in with digital keypad operator (RCUS-450).

AC Drive is a mini power saving inverter. It features the most simple AC induction motor controller from 200W up to 1.5kW for 220VAC and 440VAC Class. The status indicator LED and 7-segment display are built in and can show the data value for the easy reading. AC Drive is small, quiet and powerful.

AC Motor Drive is a small General-purpose Vector control AC inverter for convention vector control application. The copy keypad functions are operated for easy parameters setting. AC Motor Drives with 17 multi-speed settings available for the speed control. The capacity includes 0.75kW up to 7.5kW for 220VAC and 440VAC Class.
