Agilent E3640A – 45A Single Output
The new E3640A-series programmable dc power supplies are
30W/50W/80W single output dc power supplies with standard
GPIB & RS-232 interface. For general-purpose use, these pro-
grammable power supplies offer the performance of system
power supplies at a surprisingly affordable price.
Clean and Stable Output
All models deliver clean and reliable power, dependable regu-
lation (0.01%) and fast transient response (<50usec to within
15mV). With 0.01% load and line regulation, Agilent E364xA
power supplies keep output steady when power line and load
changes occur. These linear supplies specify both normal
mode voltage noise and common mode current noise to
assure less interference with your DUT.
Standard remote interface
Standard GPIB and RS-232 interfaces, SCPI programming and
plug&play drivers for Agilent VEE and NI LabView make it
easy to program and integrate into automated test systems.
You can monitor the output terminals for voltage and current,
and a query command lets you read the programmed voltage
and current.
Versatile Power
Agilent E364xA power supplies give you the flexibility to select
from dual output ranges. Both front and rear output terminals
are standard and output load is protected against over-voltage
protection function. Remote sense is available to eliminate the
errors due to voltage drops on the load leads. New front panel
binding posts offer flexibility to use safety test leads, banana
plugs or stripped wires. Store and recall key enables you to save
and recall up to 5 frequently used operating states.

dc Floating Voltage: Output terminals can be floated up to
±240Vdc from chassis ground.
Remote Sensing: Up to 1V can be dropped in each load
lead. The drop in the load leads subtracts from the
voltage available for the load.
Settling Time: Less than 90msec for the output voltage to
change from 1% to 99% or vice versa following the
receipt of VOLTage or APPLy command via direct
GPIB or RS-232 interface.
Product Regulation: Designed to comply with UL3111-1; certi-
fied to CSA 22.2 No. 1010.1; conforms to IEC 1010-1;
complies with EMC directive 89/336/EEC(Group1, Class A)
