3. Descriptions of HSA03-B High Power Pulse Width Modulation Amplifier

HSA03-B 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 supplies. + 15v for the small signal control circuit power supply; 16v-100v motor the power supply for the internal H bridge. The control signal of the input circuit is the DC level signal of 3v-7v. The internal output 45KHZ TTL wave signal, the output width of the square wave signal frequency is 22.5KHZ.   The key input can turn off the four drive tubes of the H-bridge circuit.
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 HSA03-B High Power Pulse Width Modulation Amplifier

HSA03-B Power supply has two current sampling end I sense-A and I sense-B.
The two terminals shall be shorted when using voltage control model . The typical connection diagram as shown in Table 4.

Typical Connection Diagram
Table 4 typical connection diagram

7.1 Power supply bypass
HSA03-B 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.
