Measuring inputs

Current measurement
AC current measurement only
The device is not suitable for measuring DC current.
SENTRON PAC4200 is designed for:
● Measuring current of 1 A or 5 A for connecting standard current transformers. Each
current measuring input can take a continuous load of 10 A. Surge withstand capability is
possible for currents up to 100 A and a duration of 1 s.
Voltage measurement
AC voltage measurement only
The device is not suitable for measuring DC voltage.
SENTRON PAC4200 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 400 V / 690 V (max. 347 V / 600 V for Vph) on devices with a
wide-voltage power supply. The device is designed for measuring input voltages up to
400 V (347 V for Vph) phase-to-neutral and 690 V (600 V for Vph) phase-to-phase.
