The SK-H1-GDB1-F11D is a gate drive board specifically engineered for Allen Bradley's PowerFlex 700 series AC drives. This module operates efficiently within a voltage range of 400 to 480 Volts AC. Designed to maximize electrical performance, it boasts an efficiency rate of 97.5% at its rated amperage. For the PowerFlex 700H model, three boards are required, while only one board is necessary for the PowerFlex 700S.
In terms of environmental resilience, this gate drive board endures shocks of up to 15G for a duration of 11 milliseconds in non-operational conditions. It is built to handle a wide operational temperature range of -40°C to 60°C (-40°F to 140°F), which makes it suitable for diverse installation environments.
The device can safely remain stored at temperatures up to 70°C (-40°F to 158°F). Designed for use in humid conditions, the board can function effectively within 5% to 95% relative humidity, provided that condensation is absent. It features a conformal coating for added protection against environmental factors, which is beneficial for extending the lifespan of the module.
This component is engineered with safety in mind, meeting several regulatory standards, including ATEX, AS/NZS, NFPA 70, CE, and cULus. The gate drive module employs fan cooling to moderate its operating temperature and is rated for vibration resistance up to 1G. The physical size of the frame is categorized as Size 11, ensuring compatibility with designated installations within the operational framework.
