Physical Characteristics and Installation
This snubber board weighs approximately 0.60 kg for secure rack mounting. Its dimensions measure 280 mm x 80 mm x 25 mm for Mark V drive racks. First, align the DS200IAXSG1A DS200IAXSG1AAA 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.
Snubber Circuit Specifications
The DS200IAXSG1A DS200IAXSG1AAA provides 6 independent snubber channels for IGBT protection. Each channel uses a 0.68 µF capacitor for enhanced voltage clamping. A 3.3 Ω resistor limits the discharge current during switching events. The peak voltage rating reaches 1500V DC for high-power AA/AB applications. Each channel handles up to 75 A peak current safely. Consequently, this board prevents destructive voltage spikes across the IGBT modules.
Component Layout and Board Variants
This snubber board contains 12 capacitors for energy absorption. Twelve resistors provide current limiting and damping functions. Eight diodes offer reverse voltage protection for sensitive circuits. The DS200IAXSG1A DS200IAXSG1AAA units share identical electrical specifications. The “AAA” suffix indicates a revised PCB layout or newer component revision. The snubber circuits connect directly to the IGBT collector-emitter terminals.
