DESCRIPTION:
The MSK4854 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 MSK4854 allow high
power outputs at elevated baseplate temperatures.
