This transducer must be used in electric/electronic equipment
with respect to applicable standards and safety requirements
in accordance with the following manufacturer's operating
instructions.
Remarks
Caution, risk of electrical shock
VOUT is positive when IP flows in the direction of the
arrow.
This transducer induces into the primary circuit a
square wave of 500Hz. This voltage can induce an AC
current in the primary if the primary impedance is low.
Primary impedance 10CT0.1-P CT0.2-P CT0.4-P
VOUT by induced current ±0.5% ±0.4% ±0.2% of IPN
Temperature of the primary conductor should not
exceed 100°C.
When operating the transducer, certain parts of the module can
carry hazardous voltage (eg. primary busbar, power supply).
Ignoring this warning can lead to injury and/or cause serious
damage.
This transducer is a built-in device, whose conducting parts
must be inaccessible after installation.
A protective housing or additional shield could be used.
Main supply must be able to be disconnected.
