DC-powered actuators, filters, and power supplies
If you are connecting DC-powered actuators, you must connect snubber filters to absorb the
transient energy the motors generate. Installing filters helps extend the life of Power Block relays.
For more information, read
Reducing electrical noise using filters
on page 19.
Phason offers two models of DC-actuator power supplies. Both models are CSA-approved
and
include snubber filters
.

DC power supply
(124-0) – in18 and –18 VDC fused outputs and a snubber filter, all
mounted in an enclosure.

DC power supply
(124-1) – in18 and –18 VDC fused outputs and a snubber filter, all
mounted in a large enclosure. The enclosure has room for two power contactor kits (PC-240 or
122-1).
A 36-V DC-powered actuator positions more slowly and accurately with an 18-V power supply, but
has less thrust. For more information about power supplies or other Phason accessories, see your
dealer or visit

Supra relay ratings
: 10 A at 120/230 VAC, general-purpose (resistive)
1/3 HP at 120 VAC, 1/2 HP at 230 VAC
360 W tungsten at 120 VAC
If you are connecting an actuator that exceeds the relay ratings, you must install a
power contactor. For more information, read
Using power contactors to increase the
capacity of relays
on page 20.
To connect actuators
Connect actuators to the Supra as shown in the following diagrams. Refer to your actuator’s
installation guide for information about its power supply requirements.
Refer to
Appendix D: Installation worksheet
on page 123 and
Appendix E:
Configuration worksheets
on page 125 when installing actuators.

When connecting a feedback potentiometer, connect it to ACT1 for actuator 1
and ACT2 for actuator 2.

If you are unsure of the potentiometer wiring for your actuator, see
Determining
correct actuator feedback wiring
on page 121.

When routing the actuator feedback wires, do not run them in or along the same
conduit as AC-power lines. Follow the guidelines in the
Control fundamentals
.

If you are measuring AC power with a DMM, note that if a limit switch opens the
circuit, the DMM measures voltage after the relay switch even if the relay is open.
