The LGDS-300 features 3 modes of operations as follow:
- Normal operation: Normal operation occurs in between the permanent input voltage of the DC/DC converter; The LGDS-300 is then operating in steady transparency state.
- Power fail operation: The power fail operation occurs when the input bus drops below 9 Vdc low voltage limit; an undervoltage lock-out stops the LGDS-300.
- Transient operation: The LGDS-300 clamps input transient up to 80V/100ms or 100V/50ms.
The LGDS-300 series is compliant with the international input bus standards:
- AECMA EN2282
- DO160E 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 severe environmental conditions.
