is reversed (such as when timing the closing and opening of a single contact as
in measuring the trip-free operating time of a circuit breaker).
Stop Latch:
The Timer Stop Gate latch feature which allows timing to be stopped at the first
operation of any Stop Gate (thus ignores contact bounce). When unlatched, the
Stop Latch allows timing to be stopped by any Stop Gate and then restarted if the
Stop Gate reverses (provided a Start Gate is still energized), and then stopped
again when the gate reverses (total time including contact bounce).
Protection
Input and outputs are protected from short circuits and prolonged overloads.
Ancillary Interface:
A voltage signal output, in phase with the main
current output (± 3
°
), is provided to input into
the MEGGER Models EPS-1000 or PVS-1000
for phase reference. This will allow testing of
more complex relays, which require phase
shifting between a three-phase voltage output
(EPS-1000) and a current output (SR-98).
Temperature Range
Operating:
32 to 122
°
F (0 to 50
°
C)
Reduced duty cycle:
Duty cycle is linearly de-rated from 3 minutes on,
starting at 104
°
F (40
°
C) to 1 minute on at 122
°
F
(50
°
C), followed by 20 minutes off.
Storage:
-40 to 158
°
F (-40 to 70
°
C)
Relative Humidity:
90% RH, Non-condensing
Enclosure
The unit comes mounted in a rugged plastic transit case for field portability. The
tongue and groove lid protects the unit from rain and dust intrusion. Spring
loaded carry handles are located on each side for convince.
