MAG AMP CORES

Square Loop Cores manufactured with cobalt based amorphous alloy allow the design of mag amps that can operate at higher frequencies than previously possible. Their combination of magnetic properties enables mag amps to provide unparalleled precision and efficiency in output regulation.

Amorphous are particularly well suited for output with currents of 1 amps to several tens of amps, although they are also used at lower currents when tight regulation and efficiency are extremely important.

Conventional regulated outputs are limited at higher frequencies and output currents. Linear regulators cannot handle output currents that exceed one or two amperes efficiently and thus require heat sinking schemes, which increase size of the power supply. Independent switched mode sub-regulators avoid this inefficiency, but usually require circuitry which is more complex, expensive and less reliable than mag amps standard size are available from 9.6 mm to 34.0 mm OD and the possibility of manufacturing custom size also exists. Core coating meeting UL94v-0 and temperature class F are available upon request.
