Apex Microtechnology MSA260 Open Frame PWM Amplifier
Apex Microtechnology MSA260 Open Frame PWM Amplifier is a 20A (30A PEAK), 450V pulse width modulation (PWM) amplifier. It's constructed as a surface mount, "open frame" board-level module as a cost-effective solution for motor control applications. The MSA260 has outstanding performance and is an excellent substitution for more expensive hybrid components. The MSA260 is a complete PWM amplifier including an oscillator, comparator, error amplifier, and current limit comparators. It has a 5V reference, a smart controller, and a full-bridge IGBT output circuit. A variable switching frequency is user programmable up to 50kHz. The MSA260 is built on a thermally conductive, but electrically insulating, substrate that can be mounted to a heatsink.
