GE IS200RCSAG1ABB RC Snubber Board

FAQ

Q1. What is IS200RCSAG1ABB?
IS200RCSAG1ABB is an RC snubber board used in GE Mark VI Speedtronic / EX2100 excitation control systems to protect SCRs and diodes from voltage transients.

Q2. What function does the snubber board serve?
It suppresses high‑voltage transients and limits the rate of voltage change (dv/dt) during switching of power semiconductors, improving reliability and system longevity.

Q3. Which control systems use this board?
It’s designed for use in Mark VI Speedtronic and EX2100 turbine excitation control systems from GE.

Q4. What power supply voltage does it require?
The board typically operates from a 25 V DC supply.

Q5. What are its approximate physical dimensions?
The board is approximately 238 mm high and 86 mm wide.

Q6. How much does it weigh?
It weighs about 0.45 kg.

Q7. What environment can it operate in?
It is suitable for industrial excitation control cabinet environments with an operating temperature range from −35 °C to +65 °C.

Q8. Why is snubber protection important?
Snubber protection prevents damage from electrical stress and reduces electromagnetic interference, enhancing safe and stable operation of high‑power excitation modules.
