SN-HH Series Specifications
High Horsepower Modular Design
Description 800~1600HP
The SN-HH series drive is a high performance product that produces an output of adjustable voltage and frequency
to control the speed of a squirrel cage induction motor. These modular design units have separate converter
capacitor inverter sections installed in a common enclosure. Sections can be paralleled to increase capacity. 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). Programmability,
network capability, and flexibility are outstanding.
