Front-Panel Voltage and Current Limit Settings
You can set the voltage and current limit values from the front panel using the
following method.
1Select the desired range using the range selection keys after turning on the
power supply.
2Press the #key to show the limit values on the display.
3Move the blinking digit to the appropriate position using the resolution
selection keys and change the blinking digit value to the desired voltage limit
by turning the control knob. If the display limit times out, press the key
again.
4Set the knob to current control mode by pressing the key.
5Move the blinking digit to the appropriate position using the resolution
selection keys and change the blinking digit value to the desired current limit
by turning the control knob.
6Press the #key to enable the output. After about 5 seconds, the display
will go to output monitoring mode automatically to display the voltage and
current at the output or the display will go to output monitoring mode
immediately by pressing the #key again.
Note All front panel keys and controls can be disabled with remote interface commands.
The HP E3633A and HP E3634A must be in "Local" mode for the front panel keys
and controls to function.
Use thevoltage/current adjustselection key,the resolution selectionkeys,
and the control knob to change the voltage and current limit values.

otherwise stated, the information in this manual applies to both two models.
This chapter provides a general description of your power supply. This chapter also
contains instructions for initial inspection, location and cooling for bench and rack
operation, selecting the power-line voltage, and connecting your power supply to ac
power.
Safety Considerations
This power supply is a Safety Class I instrument, which means that it has a protective
earth terminal. That terminal must be connected to earth ground through a power
source with a 3-wire ground receptacle.
Before installation or operation, check the power supply and review this manual for
safetymarkingsandinstructions.Safetyinformationforspecificproceduresislocated
at the appropriate places in this manual. See also ‘‘Safety’’ at the beginning of this
manual for general safety information.

Description
The HP E3633A and HP E3634A DC power supplies feature a combination of
programmingcapabilitiesandlinear powersupplyperformancethatmakesthemideal
for power systems applications. The power supply is programmable locally from the
front panelor remotely over theHP-IBand RS-232interfaces.Thispower supply has
two ranges, allowing more voltage at a lower current. An output range needed is
selected from the front panel or over the remote interfaces.
Operational features include:
• Dual range of single-output: 8V/20A and 20V/10A (HP E3633A),
25V/7A and 50V/4A (HP E3634A)
• Constant voltage (CV) or constant current (CC) operation
• Overvoltage protection (OVP) and overcurrent protection (OCP)
• Three storage locations (1 to 3) for user-defined operating states
• Automatic turn-on self-test
• Remote sensing for load voltage at the front or rear panel terminals
• User calibration from the front panel or over the remote interfaces
The front panel operation permits:
• Easy-to-use of knob control
• Output range selection
• Enabling or disabling OVP and OCP features
• Setting the OVP and OCP trip levels
• Clearing OVP and OCP conditions
• Setting and displaying the voltage and current limit values
• Saving and recalling operating states
• Returning the power supply to local mode from remote interface mode
• Retrieving/Scrolling error messages on the display
• Calibrating the power supply, including changing the calibration secure code
• Configuring the power supply for remote interfaces
• Enabling or disabling the output

When operated over the remote interface, the powersupply can be both a listener and
a talker. Using an external controller, you can instruct the power supply to set the
output and to send the status data back over the HP-IB or
RS-232. Capabilities include the following features:
• Voltage and current programming
• Voltage and current readback
• Present and stored status readback
• Programming syntax error detection
• Complete self-test
The front-panel VFD (Vacuum-Fluorescent Display) includes:
• Displaying actual values of output voltage and current (meter mode)
• Or displaying the limit values of voltage and current (limit mode)
• Checking the operating status from the annunciators
• Checking the type of error from the error codes (messages)
Connections to the power supply’s output and to chassis ground are made to binding
posts on the front panel and to the rear output terminals.
Warning Floating the power supply output more than ±60 Vdc from the chassis presents an
electric shock hazard to the operator. Do not float the outputs more than ±60 Vdc
when metal shorting bars without insulation are used to connect the (+) output to the
(+) sense and the (-) output to the (-) sense terminals.

Chapter 1 General Information
Description

Warning Outputs canbe floated to maximumof ±240 Vdcprovided that the metal shorting bars
without insulationare either replaced with insulated conductorsor they are removed
from the terminals so there is no operator access to the output conductors without
insulation. All field wiring insulation must be adequate for the voltage present.
The power supply is shipped with a detachable, 3-wire grounding type power cord.
The ac line fuse is an extractor type on the rear panel. The power supply can be
calibrated from the front panel directly or with a controller over the HP-IB or RS-232
interface using calibration commands. Correction factors are stored in nonvolatile
memory and are used during output programming. Calibration from the front panel
or a controller eliminate the need to remove the top cover or even the need to remove
the power supply from your system cabinet. You can guard against unauthorized
calibration by using the “Secured” calibration protection function.

Installation
Initial Inspection
When you receive your power supply, inspect it for any obvious damage that may
have occurred during shipment. If any damage is found, notify the carrier and the
nearest HP Sales Office immediately. Warranty information is shown in the front of
this manual.
Keep the original packing materials in case the power supply has to be returned to
Hewlett-Packard in the future. If you return the power supply for service, attach a tag
identifying the owner and model number. Also include a brief description of the
problem.
Mechanical Check
Thischeck confirms that there are no broken keys or knob, that the cabinet and panel
surfacesarefreeofdentsandscratches,and thatthedisplayis notscratchedorcracked.
Electrical Check
Chapter 2 describes an initial operation procedure which, when successfully
completed, verifies to a high level of confidence that the power supply is operating
in accordance with its specifications. Detailed electrical verification procedures are
included in the Service Guide.
Cooling and Location
Cooling
The power supply can operate without loss of performance within the temperature
range of 0 °C to 40 °C, and with derated output current from
40 °C to 55 °C. A fan cools the power supply by drawing air through the rear panel
andexhaustingit outthesides.UsinganHPrackmountwillnotimpedetheflowof air.
Bench Operation
Your power supply must be installed in a location that allows sufficient space at the
sides and rear of the power supply for adequate air circulation. The rubber bumpers
must be removed for rack mounting.
