3.2. ELECTRICAL CHARACTERISTICS

3.2.1. VOLTAGE
Nominal voltages: 12, 24, 50, 127, 230, 400, 690 V
and 750 V .
dc
Frequency of operation: DC and 16.67 at 800Hz.
Maximum input current: 3.5 mA
Input impedance >300kW.
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).
3.2.2. CONTINUITY AND RESISTANCE
Continuity detection is disabled if a voltage > 1V is present.
The triggering thresholds are:
„ 100W<R<150W
2kW<R<3kW
„
„ 60kW<R<90kW
„ 300 W<R<450kW
Test current ≤1mA
Open-circuit voltage ≤3.3V
