SECTION 1 - TECHNICAL SPECIFICATION
PXI ISOLATED POWER SUPPLY MODULE 41-720
pickering
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
“partial loaded” version, if all three are supplied it is as the
“fully loaded” part.
Mating Connectors & Cabling
For connection accessories for the 41-720 module please
refer to the 90-003D 9-pin D-type Connector Accessories
data sheet where a complete list and documentation can be
found for accessories.
