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