Clean and Stable Power with Programmability
at an Affordable Price
Affordable programmable power supplies to meet your needs
The Keysight Technologies, Inc. E363xA Series of programmable DC power supplies gives
you the performance of the system power supplies at a decent price. All models provide
clean power, excellent regulation and a fast transient response with built-in GPIB and
RS-232 interfaces. The E363xA Series is designed to meet the requirements of the most
demanding applications in R&D design verications, production testing, and QA verica-
tions with traditional quality and reliability which you can count on.
Excellent performance you can trust
With the 0.01% load and line regulation, the E363xA Series can maintain a steady output
when power line and load changes occur. The power supplies specify both normal mode
voltage/current noise and common mode current noise. The low normal mode noise
specication assures clean power for precision circuitry applications, and the low com-
mon 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 the rst-time programmers.
Front panel operation
A knob and self-guiding keypads allow you to set the output at your desired resolution
quickly and easily. You can store and recall for up to three complete setups using 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 outputs: 0 to 6 V/5A,
0 to +25V/1A and 0 to –25V/1A. The 6 V output is electrically isolated from the ±25 V
supply to minimize any interference between circuits under test. 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 exibility to select from a dual output
range. The output load is protected against overvoltage and overcurrent, which are
easily monitored and adjusted from the front panel and remote interface. Remote sens-
ing is available to eliminate the errors caused by voltage drops on the load leads. The
E3633A/34A offer front and rear output terminals for easy wiring.
