DESCRIPTION:This split-core current trans-
former was designed for easy installation on
large bus or wire conductors in order to
make electrical load surveys or for continu-
ous monitoring of current.
APPLICATION: To be used with any 5 amp
indicating or recording ammeter or amp or
watt transducer.
CONSTRUCTION: Directional silicon steel is
used for the flexible core. Secondary wind-
ings are of copper. Unit is encapsulated in
silicone rubber which protects against mois-
ture, dirt, oil and corona. Remains flexible
from -45° to +200°C.
INSULATION LEVEL: 600VAC - can be
used over insulated conductors on higher
voltage circuits. Rubber inserts are available
for a more precise fit to your conductor.
FREQUENCY: 50 - 400hZ
SAFETY FACTOR: A self-contained voltage
clamping circuit prevents dangerous high
voltage across the secondary windings in
case of accidental opening of the output
leads when the primary circuit is energized.
This circuit will trigger within 10 micro-sec-
onds when the secondary voltage rises to 40
volts or more, clamping the output to less
than 1 volt.
SECONDARY LEADS: 12 feet long with
spade connectors. Custom lead lengths are
available.
COLOR: Transformer (red) - leads (yellow)
