4.2. ELECTRICAL CHARACTERISTICS
4.2.1. VOLTAGE
Nominal voltages: 12, 24, 50, 127, 230, 400, 690 Vac/Vdc
and 750 Vdc.
Frequency of operation: DC and 16.67 at 800Hz.
Maximum input current: 3.5 mArms.
Internal impedance at 50 Vac: 850 kΩ.
Response time <500ms.
The indicator corresponding to voltage V lights before the
voltage reaches 85% V.
If no indicator lights, the voltage present is < 12V.
The C.A 762 IP2X must be used only on networks at stand-
ardized voltages.
Operating cycle: 30s (maximum duration for which the device
can remain connected to a live element) - 240s (minimum
resting time during which the detector must not be connected
to a live element).
4.2.2. CONTINUITY AND RESISTANCE
Continuity detection is disabled if a voltage > 1V is present.
The triggering thresholds are:
