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 ≥10Ω CT0.1-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.
