3.1 Features
SENTRON PAC4200 is a Power Monitoring Device for displaying, storing, and monitoring all
relevant system parameters in low-voltage power distribution. It is capable of single-phase,
two-phase, or three-phase measurement and can be used in two-wire, three-wire, four-wire,
TN, TT, and IT systems.
Thanks to its compact design in 96 x 96 mm format, it is an ideal replacement for all
conventional analog indicating instruments.
With its large measured voltage range, SENTRON PAC4200 with a wide-voltage power
supply can be connected direct in any low-voltage system up to a rated system voltage of
690 V (max. 600 V for Vph).
Higher voltages can be measured using voltage transformers. For measuring current,
either x / 1 A or x / 5 A current transformers can be used.
The large graphical LC display permits reading even from a distance. SENTRON PAC4200
has adjustable backlighting for optimal readability even under poor lighting conditions.
The combination of four function keys with the multi-language plaintext displays makes
intuitive user prompting possible. The experienced operator can also use direct navigation
for quicker selection of the desired display menu.
SENTRON PAC4200 guarantees high measuring accuracy. It can be used to capture and
store load profiles according to various methods. It has a range of useful monitoring,
diagnostics, and service functions, a two-tariff active energy and reactive energy counter, a
universal counter, and an operating hours counter for monitoring connected loads. A
comprehensive, parameterizable signaling system allows application-specific monitoring of
various events, such as limit violations or operator interventions.
The volatile memory of the device and the internal clock are battery-backed.
The integral Ethernet interface or an optional expansion module can be used for
communication.
SENTRON PAC4200 has two multifunctional digital inputs and two multifunctional digital
outputs.
The parameters can be set either direct on the device or with the SENTRON powerconfig
configuration software.
Password protection is integrated to guard against unauthorized access.
