DESCRIPTION:

The MSK 4851 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/200 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 MSK 4851

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 requirements of military and aerospace applications. MSK PEM's are also avail-

able with industry standard silicone gel coatings for a lower cost option.
