Chauvin Arnoux CA 762 Voltage Detector DDT/VAT (12 Vac ≤ U ≤ 690 Vac; 12 Vdc ≤ U ≤ 750 Vdc)

Voltage Detection

Voltage range: 12 Vac ≤ U ≤ 690 Vac; 12 Vdc ≤ U ≤ 750 Vdc

Frequency: DC, 16 2/3 to 800 Hz

Impedance: > 400 kΩ

Maximum current: 3.5 mA RMS

Polarity indication: Yes

Dangerous voltage indication: The red ELV (Extra Low Voltage) indicator shows that the voltage is above the SELV (Safety Extra Low Voltage) level and flashes faster as the present voltage increases.

Phase / Neutral Identification

Above 120 V* (45–65 Hz)

Above 400 V (16 2/3–45 Hz)

Continuity with Buzzer

Trigger threshold: 100 Ω typical (150 Ω max.)

Extended continuity test: 2 kΩ, 60 kΩ, 300 kΩ

Test current: ≤ 1 mA
