3.2 Measuring inputs
Current measurement
CAUTION
AC current measurement only
The device is not suitable for measuring DC current.
SENTRON PAC3100 is designed for:
● Measuring current of 5 A for connecting standard current transformers. Each current
measuring input can take a continuous load of 10 A (max. 300 V). Surge withstand
capability is possible for currents up to 100 A and a duration of 1 s.
Voltage measurement
CAUTION
AC voltage measurement only
The device is not suitable for measuring DC voltage.
SENTRON PAC3100 is designed for:
● Direct measurement on the system or using voltage transformers. The measuring voltage
inputs of the device measure direct via protective impedances. External voltage
transformers are required to measure higher voltages than the permissible rated input
voltages.
● Measuring voltage up to 277 V / 480 V. The device is designed for measuring input
voltages up to 277 V to the neutral conductor and 480 V to the external conductor.
