10- Application Notes (continued)
The power fail voltage threshold determines the operation
mode of the HUGD-50.
This threshold has to be set up in conjunction with the
type of modules used (i.e. 9-36 VDC or 16-40 VDC input
voltage type of modules) and can be adjusted between
8,8VDC and 15,3VDC by external resistance Rth connected
between the Vth pin and Gout pin.
The HUGD-50 controls the inrush current (charging current)
to remain between 100 mA to 2A by an external resistance
Rcl connected between the Vcl pin and the Gout pin. This
charging current is a direct function of the charging time

Vth unconnected will set up the threshold at 15,3VDC valid
for 16-40Vdc input modules, Vth connected to ground will
set up the threshold at 8,8VDC valid for 9-36Vdc input
modules.
If the HUGD-50 is used with the PGDS-50-N-K, Vth has to
remain unconnected; with the PGDS-50-O-K, Vth has to be
connected to Go. The following curve determines the
function of Vth threshold as a function of the resitor Rth.
knowing that the capacitor is charged at 38VDC. The
following curve gives the resistance Rcl value as a function
of current & charging time.
