GAIA Converter Transient Protection Module 50 W - PGDS50 Series

The GAIA Converter pre-regulator PGDS-50 series designates a low profile power adaptator module designed to extend input bus voltage to meet system operation during voltage transients, spikes, cranking and drop out occuring in avionics or military systems. The PGDS-50 delivers an output voltage adapted to GAIA Converter DC/DC modules. This line of module is optimized to provide high power efficiency up to 96% over the whole power range between 4W and 50W. 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 6V. 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 80V/100ms or 100V/50ms.
