Interface Signals and Internal Protection
PARAMETER CONDITIONS/DESCRIPTION MIN NOM MAX UNITS
Indicators GREEN indicator for normal
operating mode.
RED indicators for power fail
and excessive internal temperatures.
Power Fail Warning Logic LOW to 1000MC control card 0.7 VDC
(TTL compatible) (denotes power fail detected).
Logic HIGH with internal pull-up 10 k ohm
to output.
Output low voltage trip point. 11.6 11.8 12.0 VDC
Power fail trip point, maximum 30 36 38 VDC
load, decreasing input.
Time before regulation dropout, 200 us
full load, due to loss of input power.
Alarm Contacts Normally-open and normally closed
contacts via 3-position terminal block
(1A@30V). Contacts operate upon
power failure detection.
Overtemperature RED indicator. Shifts power fail
Indication signal to a logic LOW state.
Output voltage during 4 4.5 5 VDC
overtemperture condition
User Controls Single jumper to select
“maintenance mode.” (No alarm
if PS is removed).
