OPTIONS — HIGH POWER MODELS
METER RELAYS
Over-voltage and/or over-current protection. Turns off HV
section and lights indicator lamps at preset levels. On motorized
systems, stops voltage rise at preset level.
LINE REACTOR
Panel switch bypasses overload circuit and inserts line reactor
in series with HV transformer. Limits output to rated current.
Useful in capacitor charging and other applications where
constant current is desire.
DWELL TIMER
Sounds buzzer after timing out. Manually switched ON and
OFF. For manual controls units.
HIGH VOLTAGE WARNING CIRCUIT
120 V 250 VA terminals inside control unit for connection of
external warning lamps. Alternate ON and OFF at 1-2 second
intervals when HV is ON.
MEMORY KV METER
Additional meter. Records voltage at which test sample failed.
Normally used only on motorized units.
NOTES
• Specifications including weights and dimensions are
subject to change without notice
• On high power units (25 kW and 50 kW) specifications
provided herein are estimates only. Exact data will be
provided after receipt of order.
MOTORIZED OUTPUT CONTROLS
NOTE: The time required for the output to rise from zero to
rated voltage is optional and may be 15, 30, or 60 seconds.
Rated speed (V/s) is the rated voltage divided by the rise time.
MANUAL, SINGLE SPEED
With HV switch ON, the output of the variable transformer is
driven at rated speed while a RAISE or LOWER pushbutton is
continuously depressed. When HV is switched OFF or in he
event of failure, HV output is disconnected and the transformer
is returned to the ZERO output position at rated speed. OFF
ZERO panel lamp will glow until the zero position is attained.
Standard on 50 kW units.
MANUAL, 10:1 SPEED
Same as Manual, Single Speed except that RAISE and
LOWER is adjustable from 10 to 100% rated speed. Returns to
ZERO at rated speed.
AUTOMATIC, SINGLE SPEED
Operable in either MANUAL or AUTOMATIC mode. In auto-
matic mode, when HV is turned ON the output voltage ramps at
rated speed to preset voltage, dwells, then ramps to ZERO and
turns off HV. In event of failure, HV is turned OFF and motor
drives variable transformer to ZERO output. Adjustable meter
relay and dwell timer included.
AUTOMATIC, 10:1 SPEED
Same as Automatic, Single Speed except that rate of rise is
adjustable from 10 to 100% rated speed.
