The DS200SDCIG2A DS200SDCIG2ADA stores minimal energy (only 470 µF total). Therefore, you only need a 10-second discharge wait before handling. Use the two AC terminals for line and neutral connections. Meanwhile, the 6-pin header supplies 28V to instrumentation and logic boards.
Installation and Compatibility
You can mount this board directly into any Mark V panel slot. Use four M4 screws to secure the DS200SDCIG2A DS200SDCIG2ADA. Then connect the AC supply wires to terminals L and N. Always select the correct input voltage jumper before you power up.
The DS200SDCIG2ADA variant includes enhanced transient suppression. This version also has a wider operating temperature range. Both models replace older GE SDCIG series power boards without cabinet modifications.
Environmental and Safety Data
The DS200SDCIG2A DS200SDCIG2ADA operates from -30°C to +60°C. It does not require forced cooling at room temperature. This board also meets IEC 61000-6-2 for industrial immunity. The component side has a light conformal coating. Consequently, you should avoid heavy solvent cleaning. Use only isopropyl alcohol for spot cleaning if needed.
