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
a 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
b 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.
