INSTALLATION MANUAL FOR 
DODGE PLUG IN MODEL 250 POWER SUPPLY 
 
 
 
 
Specifications: 
 
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 
 
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 
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.  
Installation and Operating Instructions  
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
of a double-pole, double-throw 
(DPDT) switch to terminals 3, 7, and 8; the switch 
common must be connected to terminal 7.  
5.  Connect side S
of the switch to terminals 6 and 2; 
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.
