Agilent Technologies Power Supply 87422A User Manual

Agilent 87421A/87422A  
Power Supply  
Product Overview  
• Designed specifically for Agilent Technologies  
microwave system amplifiers  
• Bias cable permits remote placement  
• Compact size for easy system integration  
The Agilent 87421A and 87422A power supplies  
are universal input, dc switching power supplies  
designed to provide the bias voltages needed to  
operate Agilent microwave system amplifiers.  
The 87422A is a 90 watt, 15V dc power supply  
designed to power the Agilent 83020A microwave  
system power amplifier. One additional 12V dc  
output is provided to power a preamp such as  
the 83006A or 83017A.  
These compact power supplies are ideal for inte-  
gration into a system or for use on a benchtop.  
The 2 meter dc bias cable permits the amplifier  
to be remotely located, allowing it to be placed  
out of the way or where space is not critical.  
Included with the power supply are the necessary  
2 meter cables to connect to the amplifier.  
The 87421A may also be used to provide bias volt-  
ages for the Agilent 83440C high speed lightwave  
converter. Using the 83440-60009 lightwave con-  
verter power supply adapter, the 87421A becomes  
a compact, convenient power supply for use with  
the lightwave converter.  
The 87421A is a 25 watt, 12V dc power supply  
designed to power the Agilent 83006A, 83017A,  
83018A, and 87415A microwave system amplifiers.  
A 2 meter cable is included for direct connection  
to the amplifier.  
 
cable. For help with special applications requiring  
longer cables contact your Agilent call center listed  
on the back page.  
Other product and operating information  
Operation of the power supplies involves connect-  
ing 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.  
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.  
Mounting holes are provided as shown in the out-  
line drawings. The power supplies may be mounted  
in any orientation with user supplied hardware.  
The power supplies contain no user serviceable  
parts (with the exception of the fuse). If service is  
required, please contact your Agilent sales office  
or nearest Agilent Service Center.  
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  
The Agilent 87421A power supply provides the dc power needed to bias the 83006A, 83017A, and 83018A. The power  
supply comes with a 2 meter long cable to allow easy connection between the amplifier and the power supply.

Safety and Regulatory Information  
Manufacturer’s Declaration  
This is to certify that this product meets the requirements specified in IEC 1010 and  
IEC Publication 348, Safety Requirements for Electronic Measuring Apparatus. It has  
been supplied in a safe condition for indoor use only and may occasionally be subjected  
to temperatures between +5 and –10 Celsius without degradation of its safety. The  
present data sheet contains some information and warnings which have to be followed  
by the user to ensure safe operation and to retain the product in safe condition. The  
main plug shall be inserted in a socket outlet provided with a protective earth contact.  
The protective action must not be negated by the use of an extension cord without  
a protective conductor. Warning: Any interruption of the protective conductor inside  
or outside the product or disconnection of the protective earth terminal is likely to  
make the equipment dangerous. Intentional interruption is prohibited. This product  
has been designed to be safe under the following environmental conditions: indoor use;  
altitude up to 2,000 meters; temperature range expanded to include 0 to +55 Celsius;  
maximum relative humidity 80% up to 31 degrees Celsius decreasing linearly to 50%  
relative humidity at 40 degrees Celsius; mains supply voltage fluctuations not to exceed  
10% of nominal voltage; transient over voltage category II for the main ac supply  
voltage; pollution degree two. If the equipment is used in a manner not specified by
