DESCRIPTION:
The MSK4852 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 1200 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 MSK4852
allow high power outputs at elevated baseplate temperatures. Our proprietary coating, SEES™ - Severe Environment Encap-
sulation System - protects the internal circuitry of MSK PEM's from moisture and contamination, allowing them to pass the
rugged environmental screening requirements of military and aerospace applications. MSK PEM's are also available with
industry standard silicone gel coatings for a lower cost option.
