3. Descriptions of HSA12 Large Current PWM Amplifiers

HSA12 is a pulse width modulation type power amplifier which operates in the switching mode, it can provide 3KW maximum transmission power for the load; the product needs two power supply; +15v for the small signal control circuit power supply;16v-200v motor The power supply for the internal H bridge. The control signal of the input circuit is the analog signal circuit input or  TTL square wave input. The internal output is 400KHZ TTL wave signal,  The key input can turn off the four drive tubes of the H-bridge circuit. It has Overheat and Current-limiting protection function.
The series of the products are made of thick film hybrid integrated process, metal sealed shell package. Product design and manufacturing to meet the MIL-STD and detailed specifications of the product requirements, the quality level is H-class.

7. Typical Connection Diagram of HSA12 Large Current Pulse Width Modulation Amplifiers


Typical Connection Diagram
Fig 4 Typical connection diagram

7.1 Power supply bypass
HSA12 power supply should have plenty of bypass to ensure its correct operation, the motor power supply should add a ceramic capacitor C3, and then in parallel with a low ESR value of the bypass capacitor C4, the capacitance should be at least 10uF/ A .for VCC the same , a 0.1 μF-0.47μF / 50V ceramic capacitor C1 and a low ESR value of 6.8μF-10μF/50V bypass capacitor C2. All bypass capacitors should be connected as close as possible to the corresponding root of  power port.
