Use
●
For 2-way and 3-way Powermite 599 MT Series, 599-02000 - 599-02079
●
Typical application in chilled ceiling, VAV, unit ventilators, fan coil unit and other terminal
unit applications
●
Max.10 units of SSC161.05DU, SSC161S.35DU are able to operate in parallel, provided
the controller output suffices.
●
For 3-position actuator, SSC131.39U, 24 actuators can run in parallel.
●
SSC131.39U floating fail-safe actuators cannot be run in parallel with legacy SSC81.5U
actuators.
●
For parallel operation of floating fail-safe SSC actuators all actuators in parallel must be
the same part number.
Technical design
When the actuator is driven by DC 0...10 V positioning signal, it produces a stroke, which is
transmitted to the valve stem.
3-position control signal (for SSC131.39U only)

Voltage at Y2:
●
No voltage at Y1 or Y2:
●
Voltage applied to both Y1
and Y2 (not recommended):
When no power is supplied, the
SSC131.39U actuator fails with
the stem fully retracted.
