87421/22A Power Supply

The 87421A and 87422A power supplies are universal input, dc switching
power supplies designed to provide the bias voltages needed to operate
microwave system amplifiers.

87421A Power Supply The 87421A is a 25 watt,

83006A, 83017A, and 87415A microwave system amplifiers.

• The power suppl y includes an A C po wer cor d with protect i ve grou nd for

connection to 90-240 Vac.

• Also included is a 2 meter cable wi th a 3-pin conne ctor on one end and a

D-subminiature connector (83006-60005) on the other end for direct
connection to the microwave system amplifiers.

The 87421A may also be used to provide bias voltages for the 83440C high
speed lightwave converter. Using the 83440-60009 lightwave converter
power supply adapter, the 87421A becomes a compact convenient power
supply for use with the lightwave converter.

87421/22A Power Supply

87422A Power Supply The 87422A is a 90 watt,

83020A microwa v e system power amplifie r. One additional ±12 V dc output
is provided to power a preamplifier such as the 83006A or 83017A.

The power supply includes an AC power cord with protective ground for
connection to 90-240 Vac and two 2 meter cables:

• one cable (83006-60005) with a 3-pin connector on one end and a

D-subminiature connector on the other end

• one cable (87422-60001) for direct connection to the 83020A amplifier

Operating and Service

Operating and Service

Operating Instructions To operate the power supplies, connect the power supplies output to the

amplifier dc input with the cable provided. The power supplies include a
power cord with protective ground for connection to 90-240 Vac.

Mounting holes are provided as shown in the diagrams. The power supplies
may be mounted in any orientation with user supplied hardware.

NOTE

•To ensure continued compliance to product safety and EMC

specifications, connect the power supplies to an amplifier only with the
cable provided.

•Do not attempt to modify or extend the dc output cable. Contact your

local Agilent Technol ogies Sales a nd Service office for help with s pecial
applications requiring longer cables.

Fuse Replacement The power supplies have a fuse located next to the IEC appliance inlet. If it

is necessary to replace the fuse, disconnect the power supply from both AC
power and the amplifier. Using a slotted screw driver, open the fuse cover
and replace the fuse.

Service Information The power supplies contain no user serviceable parts (with the exception of

the fuse). If service is required, contact your nearest Agilent Technologies
Service Center. Refer to “Service and Support” on pagev.
