IRMDAC2
IR2133 Reference Design Kit:
3-Phase 230VAC 3HP Motor Drive
Product Description
The IRMDAC2 Reference Design is a kit of parts
that work together as an evaluation platform for
IR2133 three phase motor control IC and
IRPT2056A power module. User connects three
phase AC, drive signals, motor and hall sensors to
complete the system. Power hook-up is via terminal
blocks and control signals are made using a single
in line header.
