Multifunctional measurement module of 3 phase POWER LINE
DI
DO
AI
3 × U; 3 × I
(3 phase power
line)
SMM-33
Basic features
• Module is designed for measuring and monitoring of basic
values in 3 phase power line 3 × 230 Vef.
• Measured values:
– Phase voltage and current
– Line voltage and current
– Active and reactive power
– Power factor
– Total harmonic distorsion (THD) of voltage and current.
– Frequency
• Inputs are designed for direct connection of voltage
3 × 230 Vef and separated current inputs up to 5 Aef.

Connection
• Module is powered from 230V AC.
• Voltage is connected via fuse directly to inputs L1, L2, L3.
• Signals from current transformers are connected to pair
of I1 (l, k) I2 (l, k) a I3 (l, k) terminals.
• It is necessary to take care about the orientation of transformers and phase order.
• SMM-33 module is to be connected to the Foxtrot basic
module by CH2 equipped with RS-485 inteface submodule.

• For monitoring of 1 and 3 phase power supply network
230 V AC.
• Besides voltage and current you can get value of actual active
and reactive power in all phases and this information can
be used for automation of connected object. For example
for monitoring 1/4 hour maximum.
• For permanent monitoring of power factor and harmonic
distortion, whose change may indicate wrong connection
of devices.
• In residential buildings measured data can be used for
the consumption control to avoid exceeding of maximum
current set by house main circuit breaker.
