瞬态电压抑制模块Transient Protection Front-Ends
Gaia Converter's transient protection modules are designed to protect electronic systems against high (or low) voltage transients that can occur on an input bus line.
This module family presents 4 possible modes of operations:
Normal operation: When input voltage is within the nominal input voltage range(s) of the following DC/DC converters. The module then operates in a steady transparency state.
Transient operation: The modules clamp input transients for compliance with international input bus standards such as :
- for Hi-Rel grade modules MIL-STD-704, EN2282, DO-160 and MIL-STD-1275
- for industrial grade modules EN50155, RIA12 and IEC571.
Low line operation (brownout / cranking): Only available on the PGDS models, Low line operation occurs when the input bus voltage drops down below the nominal input voltage range(s) of the following DC/DC converters, then the PGDS operates in «boost» mode to provide an output voltage compatible with the DC/DC converters. The PGDS series can sustain low line operation down to 6V.
Power fail operation: The module shuts down its output when input under-voltage, over temperature and/or output over-current conditions are met.
