Model 0901 Power Supply Operation • 5
Operation
Introduction
The New Focus Model 0901 Power Supply is a triple-
output, ±15-V DC power supply. Each of the outputs is
current limited: the banana-jack output to 100 mA and
the two micro-connector outputs to 300 mA. While
the supply can be used as a general-purpose supply, it
is primarily intended for use with those New Focus
products that require a ±15-V power supply.
Figure 1:

front panel
Getting Started
The three ±15-V outputs of the Model 0901 are all
derived from a common, 0.8-A linear supply, but are
independently current limited, as shown in Figure 2.

6 • Operation NEW FOCUS, Inc.
Since each output is independently limited, the voltage
on each output differs slightly. All three ±15-V outputs
will, however, be within ±3% of ±15 V.
Please refer to “Appendix IV: Cables” on page 12 for
instructions in connecting the Model 0901 to other New Focus
products.

Appendices
Appendix I: Changing the AC Voltage Selection
The Model 0901 can operate at 100, 120, 220, or 240 V
AC with AC frequencies of 47–63 Hz. The unit is
configured at the factory for the standard AC voltage in
the purchaser’s country.
To check the voltage setting, look at the voltage
indicator on the AC power module on the back of the
power supply.

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.
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 “Appendix II: Fuses”).
7.
Close the power-module cover.

Verify the proper voltage is showing through
the module window.

12 • Appendices NEW FOCUS, Inc.
Appendix IV: Cables
New Focus offers two types of cables for use with the
Model 0901:
Connect a Model 0921 cable to one of the 0.3-A
outputs to provide banana-jack outputs for general
laboratory use. This cable should not be used to drive a
New Focus photoreceiver or amplifier from the Model
0901’s 0.1-A banana-jack output since it provides
insufficient current for New Focus products.
The colored male-banana plugs on the Model 0921
cable follow the color-coding convention listed on
page 11 for the Model 0901 banana jacks: red is +15 V,
green is common, and black is -15 V. This cable can
also be used with a power supply other than the Model
0901 to power a New Focus product.
When powering a New Focus product with the Model
0901, use a Model 0922 cable on one of the supply’s
0.3-A Microtech connector outputs.
