Description:
Powerex AC Switch SCR Modules are
designed for use in applications requiring
phase control and isolated packaging. The
modules are isolated for easy mounting with
other components on a common heatsink.
Features:
Electrically Isolated Heatsinking
Compression Bonded Elements
Metal Baseplate
Low Thermal Impedance
for Improved Current Capability
UL Recognized (E78240)
Benefits:
No Additional Insulation
Components Required
Easy Installation
No Clamping Components
Required
Reduce Engineering Time
Applications:
Transfer Switches
AC Welders
Motor Soft Starters
Ordering Information:
