PIN FUNCTION / DESCRIPTION (CONT.)
A/S
The HAM provides a low voltage non isolated output Auxiliary
Supply (A/S) that may be used to power primary side control
and monitoring circuitry. This output is 19 – 23 Vdc, referenced
to -OUT, at 3 mA max. Do not overload or short this output as
the HAM will fail. A typical use for A/S is to power an optical
coupler that isolates the Power OK signal (Figure 6).
E/O
The Enable Output (E/O) is used to inhibit the DC-DC
converters at start up until the hold up capacitors are charged,
at which time Enable is asserted high (open state, Figure 8).
If the AC line fails, E/O goes low when the DC output of the
HAM drops below 250 Vdc.
E/O must be connected to the Gate Input of all VI-26x and
VI-J6x drivers and / or the PC pin of the V375 DC-DC converters
(Figure 4); failure to do so may cause the converters to toggle
on and off. If an external load is connected directly to the
output of the HAM, do not apply the load until the output hold
up capacitor(s) are fully charged.
In applications using VI-26x drivers and VI-26x boosters, the
E/O pin should be connected to the Gate In pin of the driver
module only, it is not necessary to connect this pin to boosters
as they are controlled by their respective driver.
The E/O pin ancillary circuitry illustrated in Figures 4 and 5
provides transient immunity. The illustrated circuitry is the
minimum required, see Figures 4 and 5.
