Power Conversion and Industrial Control Interface
The IS2020RKPSG2A functions as the RKPS VME power supply module within the Mark VI control architecture. It accepts either AC or DC input, depending on the installed power configuration.
For AC operation, the specified input range is 85-264 VAC with automatic ranging. The AC input frequency range is 47-63 Hz. For DC operation, the specified range is 120-300 VDC, while the functional description identifies 125 VDC as an input voltage reference.
The module provides a 400 W output rating. Its specified efficiency is at least 85%, which defines the relationship between input power and delivered output power under the applicable operating conditions.
The supplied environmental data specifies operation from -20 to +70 deg C and storage from -40 to +85 deg C. The allowable humidity range is 5-95% RH without condensation.

Field Installation Guidelines
- Verify the complete IS2020RKPSG2A model before installation.
- Confirm the selected input source matches the specified AC or DC input range.
- For AC operation, verify that the source frequency falls within the specified 47-63 Hz range.
- For DC operation, verify input polarity and voltage before energizing the module.
- Install the module according to the Mark VI system cabinet and VME rack configuration.
- Maintain appropriate separation between power wiring and low-level control or signal wiring.
- Secure all power connections and inspect terminals for proper mechanical retention before energizing.
- Provide cabinet ventilation consistent with the specified operating temperature range.
- Prevent condensation during operation because the specified humidity range applies to non-condensing conditions.
- Follow GE instruction manual GEI-100567 for system-specific installation and wiring procedures.
