The PGDS-50 features 4 modes of operations as follow:
- Low line operation: Low line operation occurs when the input bus voltage drops down below the permanent input voltage range of the DC/DC converter. Then the PGDS-50 operates in "boost" mode to provide an output voltage compatible with DC/DC converter. The PGDS-50 series can sustain low line operation down to 6 V.
- Power fail operation: An undervoltage lock-out stops operation and disables the "boost" mode for voltage below this low line operation.
- Normal operation: Normal operation occurs between the permanent input voltage of DC/DC converter. The module is then operating in steady transparency state.
- Transient operation: The PGDS-50 series clamps input transient up to 80 V / 100 ms or 100 V / 50 ms.
The PGDS-50 series is compliant with the international input bus standards:
- AECMA EN2282,
- DO160D cat A, B and Z,
The design has been carried out with surface mount components and is manufactured in a fully automated process to guarranty high quality. Every module is tested with a GAIA Converter automated test equipment. The modules are potted with a bi-component thermal conductive compound and packaged in a metallic case to ensure the module's integrity under high environmental conditions.
