from the device or the power source.
• Position the equipment so that access tothe mains
disconnect ON/OFF switch on the front panel readily
available.

device to OFF position to turn OFF the power to
the internal electronics. The OFF position: push the
actuator or switch rocker arm so the “O” depressed.
(To connect power to device, push the actuator or
switch rocker arm so the “1” depressed).
• Fullydisconnect the powercordofthe device from
MAIN power.
Grounding and Powering the device
• Verifythat the line voltage setting onthe rearofthe
Power Supply Model 0901 matches the local Main
Power from the power cord.
• Verifythat properfuses installed foramps andtime
delay.
• Toavoid electronic shock, connect the instrument to
properly earth-ground, 3-prong receptacles by using
the supplied power cord only . Failure to observe this
precaution can reduce equipment performance.

Model 0901 User Guide
Introduction
The Newport Model 0901 Power Supply is a triple output,
low-noise, ±15-V DC power supply. It is intended for use
with all Newport brand products which require ±15-V DC,
and can also serve as a general purpose supply for laboratory
use. It is capable of simultaneously powering three devices,
each requiring ±15 V and up to 300 mA. Two of the outputs
are provided via three-pin M8 style connectors (compatible
with other Newport products), while the third uses banana
jacks. (See Figure 1.)

Getting Started
Voltage and Fuse Selection
The Model 0901 can operate with an input of 100, 120,
220, or 240 V AC with AC frequencies of 47–63 Hz.
The unit is configured for 120 V AC at the factory; if it will
be used with a different AC voltage, this will need to be
selected on the power module on the back panel. The fuses
may also need to be changed. See below.
To check the voltage setting, look at the voltage indicator
on the AC power module on the back of the power
supply . (See Figure 2.)
Figure 2: Model 0901 rear panel showing AC power module & voltage indicator.
To change the voltage/fuses:
1. Make sure the power supply is turned off.
2. Disconnect the AC power cord.
3. Open the cover of the power module using a small
blade screwdriver or similar tool.

4. Remove the AC-voltage selection wheel from the unit.
Do not attempt to rotate the wheel while it is still
in the power module; the wheel must be removed,
turned, and then reinserted for proper operation.
(See Figure 3.)
5. Reinsert the wheel in the module so the desired AC
voltage can be viewed in the power-module window.
6. Ensure the proper fuses for the new AC voltage are
installed (see Table 1). Pull out fuse holders to replace
if needed.
7. Close the power-module cover.
8. Verify the proper voltage is showing through the
module window.
9. Reconnect the AC power cord.
Fuse Type A: Slo-Blo, 250 V, 0.5 A, i2t ≥ 1.985 A2s, 5 mm x 20 mm
Fuse Type B: Slo-Blo, 250 V, 0.4 A, i2t ≥ 1.36 A2s, 5 mm x 20 mm
Table 1: The AC power module requires two 5x20-mm, 250-V, Slo-Blo fuses. The current ratings of
the fuses should be as shown.

Operation
Output Characteristics
The outputs (three pairs of ±15 V) of the Model 0901
are all derived from a common linear supply, but each
incorporates independent current-limiting protection as
shown in Figure 4. As a result, the voltage on each
output differs slightly. The impedance of each output is
approximately 2 ohms, so an output will be reduced by
0.6 V when providing the full 300 mA. With no load,
outputs should be ±15 V ±3%.
When a load attempts to draw in excess of 300 – 330 mA
the protection is activated. This is accomplished by
reducing the voltage in order to limit the current to the
maximum rated current.

supply.

Cables
Newport offers three types of cables for use with the
Model 0901:
Model # Description
0923 cable, M8 connector (male) to M8 connector (male), 1 meter
0923-2 cable, M8 connector (male) to M8 connector (male), 2 meter
0924 cable, 3 banana plugs (male) to M8 connector (male), 1 meter
Models 0923 and 0923-2 are used to connect from the
M8 connectors on the front panel of the Model 0901 to
Newport brand products.
Model 0924 can be used for the following:
- to connect from the banana jacks on the front panel
of the 0901 to Newport brand products
- to connect Newport brand products to a supply
other than an 0901 which has banana jack outputs
- to connect to the M8 connectors on the Model 0901
front panel so as to provide ±15 V on the banana
plugs for general lab use.
When connecting cable Model 0924 to the Model 0901,
note that the colored male-banana plugs on the cable
should follow the color-coding for the Model 0901
banana jacks: red is +15 V , green is ground, and black
is -15 V.
