Installation and Operating Instructions

Model 250 is an octal-base power supply that
converts 115 VAC, 50-60 Hz to a DC voltage. It
provides one fixed 100 VDC output and one
adjustable (15 to 100 VDC) output. The Model 250 is
capable of providing DC operating voltage to 1 or 2
clutches or brakes (each with 50 watts or less power
consumption). If two units are operated with the Model
250 power supply, only one unit should be energized
at a time. Note: Switches Furnished By User.

WARNING

Only qualified electrical personnel familiar with the
construction and operation of this equipment and the
hazards involved should install, adjust, and/or service
this precaution can result in bodily injury.

DANGER

Subsequent steps require rotating parts and/or
electrical circuits to be exposed. Stay clear if unit must
be running or disconnect and lockout or tag power
source if contact must be made. Failure to observe
these precautions could result in severe bodily injury or
loss of life.

DANGER

The user is responsible for conforming to the National
Electrical Code and all other applicable local codes in
respect to wiring practices, grounding, disconnects, and
overcurrent protection. Installation of an approved
disconnecting means in the line side of the controller is of
particular importance. Failure to observe these
precautions could result in severe bodily injury or loss of
life.

1. Be sure power is locked off when wiring a power
supply installation.

2. Use adequate sized wire. No. 18 gauge is
recommend-ed for runs less than 25 feet. No. 16
gauge is recommended for runs 25 feet or longer.

3. The neutral or grounded side of the 115 VAC line
must be connected to terminal 5 on the octal socket.
A voltmeter connected between the neutral line and
line ground will read 0 volts. The hot side of the 115
VAC line must be connected to terminal 1.

Note 1: Connect switches per diagrams. Do not connect
switch for the clutch or brake in coil circuit.
Note 2: Output voltage under load of the power supply
is approximately 100 VDC with 115 VAC input. This is
suitable for clutches and brakes rated 90 VDC.

Note 3: Output voltage without load is about 160 VDC.

Model 250 used with 2 units - adjustable voltage on
unit #1, fixed 100 VDC on unit #2. Connection
Instructions (See Figure 1):

1. All connections are made to terminals on octal
socket.

2. Connect unit #1 to terminals 6 and 8.

3. Connect unit #2 to terminals 3 and 6.

4. Connect side S
(DPDT) switch to terminals 3, 7, and 8; the switch
common must be connected to terminal 7.

5. Connect side S
the switch common must be connected to terminal

6.

6. Connect 115 VAC, 50-60 Hz to terminals 1 and 5.
Warning: The neutral or grounded side must be
connected to terminal 5.

5. Connect 115 VAC, 50-60 Hz to terminals 1 and 5.
Warning: The neutral or grounded side must be
connected to terminal 5.

Wiring 2 units (adjustable voltage on unit #1)

Operation:

1. Plug power supply into octal socket.

2. Turn on power source.

3. Voltage adjustments are made by removing plug
button on top of power supply case. This will
expose a screwdriver slotted adjustment. Turn the
adjustment clockwise to increase voltage, or
counterclockwise to decrease voltage. When wired
as described above, the adjusted voltage will be
applied across unit #1.

4. With switch in position P1, unit #1 is energized with
adjusted voltage and unit #2 is de-energized.

5. With switch in position P2 (normally closed), unit
#2 is energized with 100 VDC and unit #1 is de­energized.

6. If unit fails to operate, refer to the Troubleshooting
section.

Note: If unit #1 is energized with fixed 100 VDC, and
unit #2 with adjustable DC voltage, remove lead
between terminal 2 of octal socket and P2
Add lead between terminal 2 of octal socket and P1
switch.

Operation:

1. Plug power supply into octal socket.

2. Turn on power source.

3. Voltage adjustments are made by removing plug
button on top of power supply case. This will
expose a screwdriver slotted adjustment. Turn the
adjustment clockwise to increase voltage, or
counterclockwise to decrease voltage. When wired
as described above, this same adjusted voltage
will be applied across both unit #1 and unit #2.

4. With switch in position P1, unit #1 is energized with
adjusted voltage and unit #2 is de-energized.

5. With switch in position P2 (normally closed), unit
#2 is energized with adjusted voltage and unit #1 is
de-ener-gized.

6. If unit fails to operate, refer to the Troubleshooting
section.

Model 250 used with 1 unit. Connection
Instructions (See Figure 3):

1. All connections are made to terminals on octal
socket.

2. Connect unit (clutch or brake) to terminals 6 and 8.

3. Connect switch to terminals 7 and 8; the switch
common should be connected to terminal 7. Use a
maintained contact SPDT (shown in Figure 3) or
SPST switch.

4. Connect 115 VAC, 50-60 Hz to terminals 1 and 5.
Warning: The neutral or grounded side must be
connected to terminal 5.
