Current and Voltage Controls
3 Phase-phase Max. and Min. Voltage Control
Types S 172, SYY 165
Product Description
3-phase monitoring plug-in
relay for separate upper and
lower voltage control. Often
used where the generated
electrical power is unstable
Ordering Key
Housing
Type
Output
Power supply
Monitoring relay and 3-phased measur-
ing relay for upper/lower phase-phase
voltages control
Measures if all 3 phase-phase voltages are within
set limits
Measures on own power supply
Operates irrespective of phase sequence
Upper and lower limits separately adjustable
Built-in adjustable timer function
Output: 10 A SPDT relay
Plug-in type module
S-housing
LED-indication for power supply and output ON
Power supply is the 3-phased measuring voltage
(or incorrect) in order to se-
cure the equipment. The
S 172 features built-in time
delay.
