Physical Characteristics and Installation
This field supply amplifier board weighs approximately 0.68 kg for secure rack mounting. Its dimensions measure 280 mm x 80 mm x 25 mm for Mark V generator racks. First, align the DS200FSAAG2A DS200FSAAG2ABA with the backplane connectors. Then, press firmly until the board seats completely. Finally, secure the board using the top and bottom retaining screws. A conformal coating protects the PCB from moisture and dust.
Amplifier Specifications
The DS200FSAAG2A DS200FSAAG2ABA accepts a 0V to 10V DC input from the controller. This amplifier outputs 0V to 250V DC for generator field excitation. The continuous output current reaches 15 A for normal operation. Peak current delivers 30 A during transient response conditions. A pulse-width modulated (PWM) amplifier achieves 5 kHz switching frequency for efficient power conversion.
Protection Features and Component Layout
This amplifier board includes overcurrent protection for output short-circuit conditions. Overtemperature monitoring shuts down the amplifier during excessive heat. The board contains 10 integrated circuits for PWM control and feedback. Twenty-eight capacitors provide filtering and energy storage. Twenty-two resistors establish proper gain and feedback levels. The DS200FSAAG2A DS200FSAAG2ABA units share identical electrical specifications. The “ABA” suffix indicates a revised PCB layout or newer component revision.
