WARNINGS AND CAUTIONS

WARNING - HAZARDOUS ENVIRONMENTS SYMBOL

This product is not specically designed for use in hazardous environments, for example in explosive

atmospheres. If the product is to be used in hazardous environments we recommend that the user

ensures suitable protective measures are taken.

WARNING - DANGER OF ELECTRIC SHOCK SYMBOL

This module may contain hazardous voltages. Before removing the module from the rack remove all

supplies and disconnect user I/O signals.

Unused slots in the PXI/LXI chassis are populated with blanking plates to prevent access to user

I/O signals that may be present. Blanking panels are available to order from Pickering in a variety

of slot widths. If the product is not used in this manner for example by using an extender card then

additional care must be taken to avoid contact with exposed signals.

CAUTION - HANDLING OF ELECTROSTATIC-SENSITIVE DEVICES SYMBOL

Certain semiconductor devices used in this equipment are liable to damage due to static voltage.

Observe the following precautions when handling these devices in their unterminated state, or

sub-assemblies containing these devices:

1. Persons removing sub-assemblies from equipment using these devices must be earthed by a

wrist strap and a resistor at the point provided on the equipment.

2. Soldering irons used during the repair operations must be low voltage types with earthed tips and

isolated from the mains voltage by a double insulated transformer.

3. Outer clothing worn must be unable to generate static charges.

4. Printed Circuit Boards (PCBs) tted with these devices must be stored and transported in

anti-static bags.

CAUTION - PRODUCT DOCUMENTATION SYMBOL

Suitably qualied & trained users should ensure that the accompanying documentation is fully read

and understood before attempting to install or operate the product.

SAFETY INSTRUCTIONS

All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user I/O

signals (refer to the Maintenance Section).

• Appropriate manual handling procedures should be followed as dictated by the weight of the individual module or

the combined weight of the modules & chassis.

• Should a fault occur with the module or chassis, immediately isolate and disconnect the incoming power to the

chassis and the user I/O signals.

• Ensure the equipment is installed, operated and maintained by trained and authorised personnel.

• For suitably equipped products in the event of an emergency press the red “emergency stop” button situated on

the front of the unit.

PXI ISOLATED POWER SUPPLY MODULE 41-720

SECTION 1 - TECHNICAL SPECIFICATION

pickeringtest.com

The 41-720 Isolated Power Supply module provides

ﬁxed output voltage power supplies suitable for

powering devices under test that have a medium power

consumption. The module is ideal for providing ﬁxed

voltages to the device under test and can signiﬁcantly

reduce the space needed by the test system by

eliminating the bench power supply from the system.

The output voltages are fully isolated from the chassis

and can be used as ﬂoating outputs referenced to a DC

pedestal voltage.

The module can be supplied with a variety of voltage

options, each module having up to one isolated bipolar

output and two isolated single output voltages.

The bipolar output provides two output voltages, one

positive and one negative, referenced to a common

output terminal. The outputs can be used in series for

higher voltage applications. All single output voltages

can be used to provide a positive or a negative output

by simply using either the negative or the positive

output as the reference.

The voltage regulators use a switch mode pulse width

modulated regulator that can operate at up to 80%

efﬁciency

to preserve

the available

power from the

chassis.

Width and Dimensions

Occupies 1 slot of a 3U PXI chassis

Connectors

Power supply outputs are carried either on a 9-pin male

D-type connector or 1mm sockets, the allocation of pins to

supply rails is determined by the order number. The connector

type is speciﬁed by the part number sufﬁx.

PXI bus via 32 bit P1/J1 backplane connector.

Electrical Speciﬁcation

Each module is ﬁtted with up to one bipolar output and two

single output power supplies.

Isolation Voltage

The outputs are fully isolated, maximum common mode

output voltage of 500 Volts

Power Supply Control

Each regulator can be independently turned on or off.

Bipolar Output

One ﬁtted to each module, deﬁned by xx option

Product Order Codes

For each module select one bipolar output option and two

single output voltages. Order code is constructed as:

41-720-XX-YY-ZZ-D for 9-pin D-type output connector

41-720-XX-YY-ZZ-B for 1mm socket output connectors

where XX is the option number of the bipolar output

where YY is the option number for the ﬁrst single output

and ZZ is the option number of the second single output

Allowed XX options:

Option 00 Not ﬁtted

Option 02 ±12 Volts

Allowed YY and ZZ options:

Option 00 Not ﬁtted

Option 11 5 Volts

Option 12 12 Volts

Pricing for this part is based on how many of the optional

supplies are ﬁtted. If only two are ﬁtted the price is as the
