DESCRIPTION:
The MSK4853 is one of a family of plastic encapsulated modules (PEM) developed specifically for use in military, aerospace
and other severe environment applications. The Three Phase Bridge configuration along with the SCR/IGBT brake circuit and
600 volt/150 Amp rating make it ideal for use in high current motor drive and inverter applications. The Aluminum Silicon Carbide
(AlSiC) baseplate offers superior flatness and light weight; far better than the copper or copper alloys found in most high power
plastic modules. The high thermal conductivity materials used to construct the MSK4853 allow high power outputs at elevated
baseplate temperatures. Our proprietary coating, SEES™ - Severe Environment Encapsulation System - protects the internal
circuitry of MSK PEM's from moisture and contamination, allowing them to pass the rugged environmental screening require-
ments of military and aerospace applications. MSK PEM's are also available with industry standard silicone gel coatings for a
lower cost option.
