INSTALLATION MANUAL FOR
DODGE PLUG IN MODEL 250 POWER SUPPLY
These instructions must be read thoroughly before installing or operating this product.
Specifications:
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
equipment. Failure to observe this precaution can result in
bodily injury.
Input voltage: 115 VAC 50-60 Hz
Output voltage: 15-100 VDC Nominal
Output current: 0.5 Amp Maximum
Output wattage: 50 Watts Maximum
Dimensions: 2.88” H, 2.38” W, 1.75” D
WARNING: 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.
Description:
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: 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.
Installation and Operating Instructions:
1.
2.
3.
Be sure power is locked off when wiring a power supply
installation.
Use adequate sized wire. No. 18 gauge is recommended
for runs less than 25 feet. No. 16 gauge is recommended
for runs 25 feet or longer.
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):

Plug power supply into octal socket.
Turn on power source.
Voltage adjustments are made by removing plug button
on top of power supply case. This will expose a slotted
screwdriver adjustment. Turn the adjustment screw
clockwise to increase voltage, or counterclockwise to
decrease voltage. When wired as described above, the
adjusted voltage will be applied across unit #1.
With switch in position P1, unit #1 is energized with adjusted
voltage and unit #2 is de-energized.
With switch in position P2 (normally closed), unit #2 is
energized with 100 VDC and unit #1 is deenergized.
If unit fails to operate, refer to the Troubleshooting section.

Maintenance
Fuse location and access
7.
Model 250 has an internal fuse. The fuse can be checked
without removing the power supply cover. First remove the
power supply from the octal socket. An ohmmeter connected
between pins 1 and 4 on the module will read near infinity if the
fuse has burned out. If blown then replace with type 3AG 0.6
amp fuse.
Check the power source (115 VAC, 50-60 Hz line voltage).
Is it turned on? Using an AC voltmeter, check the voltage
between terminals 1 and 5. The voltage should be between
110 and 120 VAC.
Check actual wiring against the wiring diagram. Check
to see if voltage adjustment is turned up high enough to
operate clutch or brake.
Check fuse. If the fuse is burned out, replace it with one of
the same type and rating. Review entire troubleshooting
procedure to identify reason for blown fuse.
Disconnect clutch and/or brake from power supply.
Check resistance of clutch and/or brake coils. If coil is
shorted or open it should be replaced.
Check the connections between the power supply and
the clutch and/or brake to be operated. If the connections
are loose or the wires damaged or grounded, correct the
problem.
If the above corrective actions do not restore normal
operation, the power supply should be replaced with a new
one.
Accessory Requirements
The following accessories are required for installation, but are
not supplied with the Model 250 power supply.
1. Octal socket - DODGE part number 032401.
2. Switch - One switch (SPST, SPDT, or DPDT depending upon
applications). Switch should be contact type. A minimum of
6A, 120VAC is recommended.
3. Hook-up wire - as required.
NOTE: Do not use slow-blow type fuse.
To replace the fuse, remove four fasteners holding cover of base
plug. Carefully remove the cover. The fuse is located as shown
in Figure 4. Visually check the fuse. If the fuse is burned out,
remove it, and replace with a new fuse of proper size and type.
Carefully replace the cover and fasteners.
