Application:
Voltage indicator type "high impedance HR", IEC 61243-5.
Used to check the absence or presence of voltage on the 3 phases, respectively L1, L2, L3, of a H.T.A. medium voltage switchgear, downstream of the capacitive dividing bridges.
Connects directly to the interface test points of separate voltage detector systems (SVDS) type CL-498-00 or equivalent.
The voltage presence is displayed by means of a high-efficiency LED.
Features:
Maximum operating voltage: 1080 V rms.
Nominal threshold: between 70 and 90 V ± 5%.
Nominal current at trip threshold: I = 2.5 μA.
Operating frequency: 50/60 Hz.
Presence of voltage: flashing red LED > 1 Hz.
Degree of protection: IP54, double insulation.
Dimensions: 48.5 x 39.5 x 19 mm.
