SPECIFICATIONS
Input Power
120 or 240 Vac ( specify one) ± 10% , 50/ 60 Hz
Outputs
Two indenpendently controlled adjustable outputs are available
from the test set, one ac current and one ac/ dc voltage. The
voltage output can be operated either simultaneously or
independently from the current output.
Output Current
Continuously adjustable in the following ranges:
Output Current Full Load Voltage
0 - 5 Amperes 140 Volts
0 - 10 Amperes 70 Volts
0 - 25 Amperes 28 Volts
0 - 120 Amperes 5 Volts
When the voltage is sufficient to push higher than rated current
through the load, the current ratings listed in the table can be
exceeded for short duration’ s.
Duty Cycle
Maximum time on is 5 minutes followed by 15 minutes off.
Short time overloads are possible.
AC Voltage Output ( Switch Selected)
Output Voltage Current Rating
0-240 Volts 2 Amp
DC Voltage Output ( Switch Selected)
Output Voltage Current Rating
0-240 Volts 1 Amp
Metering
Measured quantities such as AC Current, AC Voltage, DC Voltage
and Time are displayed on large, LED displays. The
Ammeter/ Voltmeter is a dual purpose meter, whose function is
switch selected. When selected as a voltmeter it will measure
either ac or dc depending on the selector switch.
AC Ammeter ( Switch Selected)
Ranges and Resolution: 0 to 1.999/ 19.99/ 199.9/ 400 Amperes
Accuracy: ± 1 % of range
Measurements: True RMS, Continuous Mode. Peak Hold in
Memory Mode
AC Voltmeter ( Switch Selected)
Ranges and Resolution: 0 to 1.999/ 19.99/ 199.9/ 400 Volts
Accuracy: ± 1 % of range
Measurements: True RMS
DC Voltmeter ( Switch Selected)
Ranges and Resolution: 0 to 1.999/ 19.99/ 199.9/ 400 Volts
Accuracy: ± 1 % of range
Measurements: Average
Timer
Display: Five ( 5) digits
Ranges and Resolution: Seconds and cycles with the following
range and resolution ( switch selected) :
Seconds: a) 0 to 999.99
b) 0 to 99.999
Cycles: 0 to 99999
Accuracy: ± least significant digit or ± 0.005% of reading
whichever is greater.
Start/ Stop/ Monitor Gate
Two identical, independent, Start, Stop or Monitor Gate circuits
are provided. To monitor operation of relay contacts or trip SCR, a
continuity light is provided for the Stop gate. Upon sensing
continuity the monitor lamp will glow and a tone generator will
sound.
The following modes are provided for the Start, Stop/ Monitor Gates:
1. Timer will start, stop or continuity indicator darkens at the
opening of normally closed contacts or when conduction
through a semiconductor device such as a triac or transistor is
interrupted.
2. Timer will start, stop or continuity indicator glows at the closing
of normally open contacts or upon conduction through a
semiconductor device such as a triac or transistor.
3. Timer will start, stop or continuity indicator glows or darkens
upon the application or removal of either an ac or dc voltage
( 60 to 300 Vac) , ( 5 to 300 Vdc) . The maximum voltage to be
applied is 300 Volts ac or dc.
4. Starting or Stopping with any selected output. The Timer can
be started or stopped when turning on or off any ( or all)
selected outputs.
5. In the Current Accurate Mode the Timer stops when output
current is interrupted.
Start Latch: The Timer Start Gate is provided with a latch
feature which allows timing to be initiated by a Start Gate and
to be stopped only by the selected Stop Gate. When
unlatched, the Start Latch allows timing to be stopped when
the Start Gate 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.
Anciliary Interface
A voltage signal output, in phase with the main current output, is
provided to input into the EPS-1000A or PVS-1000 for phase
reference. This will allow testing of more complex relays which
require phase shifting bewtween a three-phase voltage output and
a current output.
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.
