7.6 Applying the measuring voltage
The SENTRON PAC3200 with multi-range power supplyis designed for measuring in
systems with rated AC voltages to
● 400 V phase-to-neutral (max. 347 V for UL) and
● 690 V phase-to-phase (max. 600 V for UL).
The SENTRON PAC3200 with extra-low voltage power supplyis designed for measuring in
systems with rated AC voltages to
● 289 V phase-to-neutral and
● 500 V phase-to-phase.
Observe limit values
The limits given in the technical data or on the type plate must not be exceeded even at
startup or when testing the device.
Measurement of DC voltage is not possible.
External voltage transformers are required to measure higher voltages than the permissible
rated input voltages.
