2.5 mA.

2)Excluding offset and hysteresis.

3)Small signal only to avoid excessive heatings of the magnetic core.

This transducer shall be used in accordance with manufacturer instruction.

The temperature of the primary conductor shall not exceed 100°C

Power supply shall be a low voltage source and shall have an efficient

protective system against over current.

Power supply must incorporate a circuit breaker.

This transducer shall be used in an electric/electronic equipment in respect

of standards rules and applicable safety requirements.

Primary bar and output terminals can provide hazardous voltage.

This transducer is a built in device, of which conducting parts must be

inaccessible by installation.

Protective envelope or additional shield must be used.

Safety :

Caution, risk of danger

Caution, risk of electrical shock

LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
