简  介:P r o d u c t IIn rr oo m nn no ovva a t i o n FF m MSA260 MSA260 General Description Pulse Width Modulation Amplifier FEATURES LOW COST HIGH VOLTAGE - 450 VOLTS HIGH OUTPUT CURRENT - 20 AMPS 9kW OUTPUT CAPABILITY VARIABLE SWITCHING FREQUENCY IGBT FULL BRIDGE OUTPUT The MSA260 is a surface mount constructed PWM amplifier that provides a cost effective solution in many industrial applications. The MSA260 offers outstanding performance that rivals many much more expensive hybrid components. The MSA260 is a complete PWM amplifier including an oscillator, comparator, error amplifier, current limit comparators, 5V reference, a smart controller and a full bridge IGBT output circuit. The switching frequency is user programmable up to 50 kHz. The MSA260 is built on a thermally conductive but electrically insulating substrate that can be mounted to a heatsink.
