Physical Characteristics and Installation
This firing circuit control board weighs approximately 0.59 kg for secure rack mounting. Its dimensions measure 280 mm x 80 mm x 25 mm for Mark V drive racks. First, align the DS200FCRRG1A DS200FCRRG1ACA 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.
Firing Pulse Specifications
The DS200FCRRG1A DS200FCRRG1ACA provides 6 independent firing channels for three-phase SCR bridges. Each channel produces pulses with programmable width from 50 µs to 500 µs. The firing angle adjusts from 0° to 180° electrical for full power control. Pulse transformer outputs range from 5V to 15V isolated for direct SCR gate connection. A 3-phase sync input ensures proper line commutation timing.
Protection and Component Layout
2500V RMS isolation separates the low-voltage control circuits from the high-power SCR gates. This design protects the controller from voltage spikes. The board contains 14 integrated circuits for firing pulse generation and timing. Thirty-five capacitors provide filtering and pulse shaping. Thirty-two resistors establish proper current limits and timing constants. The DS200FCRRG1A DS200FCRRG1ACA units share identical electrical specifications. The “ACA” suffix indicates a revised PCB layout or newer component revision.
