To help transitionning the system in the different operating
mode, GAA Converter recommends the use of a transi-
tion capacitor. This capacitor is used to maintain output
voltage during the HUGD-50 commutation from input line
to hold up capacitor. A 100μF electrolytic capacitor is
enough for a 50W load, and this value can be reduced for
lower loads.
The table below gives the minimum required values versus
output power :
The power fail output signal is activated when the vol-
tage drops below the power fail voltage threshold. the PF
signal is an open collector output active low.
The capacitor charged signal is actived when the vol-
tage at the capacitor pins reaches 34 VDC corresponding
to an energy stored of about 90% of it’s full charge.
The CC signal is an open collector output actived
low.
The capacitor discharged signal is activated when the
voltage at the capacitor pins reaches 16.3 VDC (or 9.8
VDC) corresponding to a remaining energy of about 20%
of it’s full charge.
The CD signal is an open collector output active low.
10-9 Typical Schematics
This typical application schematics includes an EMI filter, a PGDS-50 pre-regulator, the hold-up module and an assembly of
standard DC/DC converters. Additionnal details are given in the EMI filters application notes and PGDS-50 datasheet.

Note * : Due to possible oscillations caused by surges or fast transients at the input voltage level, it is recommended to implement a RC filter on the VIMES signal; several
implementations as shown in the above figure can be tested to optimize the design. Typical values for the resistor R is 470 Ohm and for for the capacitance C is 1μF.
Note ** : When used in conjunction with PGDS-50 series, the resistance Rth of HUGD module has to be left unconnected.
