Clean and stable power with
programmability at an
affordable price
Affordable programmable power supplies
to meet your needs
The E363xA-series of programmable
dc power supplies give you the
performance of system power
supplies without the high price.
All models give you clean power,
dependable regulation and fast
transient response with built-in GPIB
and RS-232 interface. E363xA-series
are designed to meet the most
demanding applications in R&D
design verifications, production
testing, and QA verifications with
traditional quality and reliability
you can count on.
Excellent Performance you can trust
0.01% load and line regulation keep
the output steady when power line
and load change occur. The power
supplies specify both normal mode
voltage/current noise and common
mode current noise. The low normal
mode noise specification assures
clean power for precision circuitry
applications and the low common
mode current provides isolation from
power line current injection.
Remote Interface
If you have an IEEE-488 card or
RS-232 in a PC, these power supplies
will work for you. Every model comes
equipped with both GPIB and RS-232
as standard. All programming is
done in easy to use SCPI (Standard
Commands for Programmable
Instruments). The user’s guide
describes the process for first time
programmers.
Front Panel Operation
A knob and self-guiding keypads
allow you to set the output at the
resolution you need for the most
exacting adjustments quickly and
easily. Up to three complete power
supply setups can be stored and
recalled from the internal non-volatile
memory. The output on/off button
sets the output to zero.
E3631A triple-output power supply
This famous 80-watt triple output
supply offers three independent
0 to + 6 V / 5 A and 0 to
±
25 V / 1 A
outputs. The 6V output is electrically
isolated from the
±
25 V supply to
minimize any interference between
circuits under tests. The
±
25 V
outputs can be set to track each other.
E3632A/33A/34A single-output dual range
power supplies
These single output power supplies
give you the flexibility to select from
dual output ranges. Output load is
protected against overvoltage and
overcurrent, which are easily monitored and adjusted from the front
panel and remote interface. Remote
sense is available to eliminate the
errors due to voltage drops on the
load leads. E3633A/34A offers front
and rear output terminals.
