GENERAL INFORMATION
DESCRIPTION
The Model E3620A Dual Output Power Supply is a compact,
constant voltage/current limiting supply that delivers two iso-
lated 0 to 25 V outputs rated at 1 A. It is an ideal power supply
for design and breadboard work where single or dual voltages
are required. Each output voltage is continuously variable
throughout its range and separate current limit circuits protect
each output against overload or short circuit damage.
Connections to the outputs are made to binding post type ter-
minals on the front panel. The outputs can be used individu-
ally or in combination to satisfy any number of output
demands. The positive or negative terminal of each output
can be grounded or each output can be left floating. A chassis
ground terminal is located on the front panel of the supply.
The front panel also contains a line switch, output voltage
controls, an autoranging digital voltmeter and a single-range
digital ammeter, and two meter select pushbutton switches.
The meter pushbuttons select both voltage and current
monitoring for the output V1 and V2. The supply is furnished
with a detachable, 3-wire grounding type line cord. The AC
line fuse is an extractor type fuseholder on the rear heat sink.
SAFETY CONSIDERATIONS
This product is a Safety Class I instrument, which means that
it is provided with a protective earth ground terminal. This ter-
minal must be connected to an AC source that has a 3-wire
ground receptacle. Review the instrument rear panel and this
manual for safety markings and instructions before operating
the instrument. Refer to the Safety Summary page at the
beginning of this manual for a summary of general safety
information. Specific safety information is located at the
appropriate places in this manual.

INSTRUMENT AND MANUAL IDENTIFICATION
A serial number identifies your power supply. The serial num-
ber encodes the country of manufacture, the week of the lat-
est significant design change, and a unique sequential
number. The letter “KR” or “MY” designates Korea or

Malaysia as the country of manufacture respectively. For
Korea, the first one digit indicates the year (4=1994, 5=1995,
and so forth), and the second two digits indicate the week.
For Malaysia, the first two digits indicate Keysight year and
the second two digits indicate the work-week. The remaining
digits of the serial number are a unique, five-digit number
(Korea) or four-digit number (Malaysia) assigned sequentially.
If a yellow Change Sheet is supplied with this manual, its pur-
pose is to explain any differences between your instrument
and the instrument described in this manual. The Change
Sheet may also contain information for correcting errors in the
manual.
