So for example, when no
triniti
chip is detected and if the brightness is set
to 250%, then the TR-HT does not allow pulses greater than 10ms long.
With 10ms pulses, any trigger occurring within the next 50ms is ignored as
the duty cycle would be greater than 20%.
The TR-HT pulsed current cannot exceed 50A, so for a lighting rating of
5A, 1000% brightness is possible.
Additionally, the TR-HT protects itself by limiting performance according
to the table shown in
. This applies whether the
TR-HT is connected to a
triniti
light or not.
When the TR-RT's operating conditions are changed to require less output
current, The TR-HT will internally dissipate stored energy before
responding; this can take up to 2 seconds.
7.2
Triggering
Trigger pulses should have a minimum pulse width of 2μs. You can set the
sense of the TR-HT trigger input. Do this by setting the P flag from the front
panel (see
Section 12.2, Front panel commands
), the web page (see
Section 11, Webpage configuration
) or the
RE
command (see
). The effect of setting the P flag is summarised
below:
