Power Supply

The equipment power supply is obtained from:
- Rechargeable NiMh batteries - 8 x 1.2 V / 3.5 Ah
- External recharge: 85 to 256 V (50 -60 Hz)
Minimum battery charge life (per NF EN 61557-2)
Test voltage
Nominal charge
Number of measurements
5 s on nominal charge
(with 25 s pause between
each measurement)
Average battery charge life
Supposing a DAR measurement of 1 minute, 10 times per day, with a PI measurement of 10 minutes,
5 times per day, l'autonomie sera d'environ 15 jours ouvrables ou 3 semaines.
Recharge time (C.A 6545 and C.A 6547)
6 hours to recover 100% capacity (10 hours if the battery is completely run down)
0.5 hours to recover 10% capacity (charge life: 2 days approximately)
Note: It is possible to recharge the batteries while performing insulation measurements provided
that the values measured are higher than 20 MΩ. In this case, the recharging time is higher than 6
hours and depends on the frequency of the measurements.
