1. GENERAL INFORMATION
1.1. User Manual Content
This User’s Manual contains the operating instructions, installation instructions and
specifications for the ALE 802 series high voltage power supply. The instructions refer to
standard power supply models, and include checkout, installation, and operation of the 802
series. Suggestions and requirements for connecting AC power, load cables and signal
cables are given. Various operating modes and programming modes are described.
The model 802 is just one model in a broad family of HV power supplies covering the power
range from 500J/sec to 30kJ/sec in a single package, and to 1MW and beyond in parallel
systems. For more information please visit our web site at:
http://www.us.tdk-lambda.com/hp/product_html/high_volt.htm.
NOTE
This manual contains information, instructions and diagrams which apply to standard
constructions. If special features or modifications have been installed, the instructions
specific to that modification are contained in Addenda and take precedence if conflicts
exist. Please take care to refer to the correct information for your unit.
1.2. Introduction
TDK-Lambda Americas ALE model 802 are state of the art constant current switch mode
high voltage power supplies, designed to rapidly and efficiently charge capacitors in laser
systems, modulators, pulse forming networks, and a broad range of pulse generator circuits,
without the need for a series current limiting resistor. They can also be used in many
continuous DC applications including beam power for RF devices such as magnetrons,
gyrotrons, klystrons and electron beam loads.
The 802 series utilize a high frequency IGBT based series resonant inverter topology which
operates as a constant current source. This makes the supply perfect for rapidly charging
capacitors which represent a challenging load for conventional HV DC supplies using
multiplier designs.
The 802 series is available with a choice of three different front panel configurations
designed to suit different applications and end uses. All models feature the same
comprehensive remote control interface which is detailed in Section 6.2.
The 802LModel is fully instrumented with front panel meters displaying output voltage and
current, status LEDs, a key switch for OFF, LOCAL or REMOTE operation, HV ON/OFF
push-button switches, and a 10 Turn output voltage control. The rear panel features external
interlock, inhibit, remote control and slave (parallel operation) control connections.
The 802SModel can only be operated by remote control and features only status LEDs and
a power switch on the front panel. The "S" Models have been designed to operate as a slave
unit to the "L" Models or in systems where local control is not a requirement.
The 802OEM features a blank aluminum front panel and can only be operated by remote
control.
As many 802 supplies as required, can be connected in parallel to provide greater output
power.

Rep rates from single shot to kilohertz.
Local (L Model) or remote operation with comprehensive control interface.
Cost effective blank front panel version for OEM applications.
Constant current topology for rapid efficient charging.
Parallel operation (master/slave) for high power applications.
Compact Air Cooled design.
Passive Power Factor Correction reduces RMS current draw.
1.3.2. Benefits
Lightweight switchmode design.
Rack mount chassis configuration.
Low stored energy provides greater safety.
Constant current design eliminates series current limit resistance in charge circuit.
Immunity to external EMI.
1.3.3. Applications
Charging capacitors and capacitor banks.
Powering pulse forming networks/modulators.
Powering lasers: Excimer, flashlamp pumped dye, Yag, CO2, etc.
Continuous power for RF tubes –magnetron, gyrotron, TWT, klystron etc.
Electron beam applications.
DC power source for pulsed hard-tube and solid state modulators.
1.4. Capacitor Charging Technology
Capacitor charging applications require a power supply designed specifically for the task.
The 802 series supplies allow capacitors to be charged in pulse forming networks and
modulators in a very fast, efficient and controllable manner.
The units are compact high power constant current sources that can linearly and rapidly
charge a capacitive load to high voltage. Once the load capacitor is charged to the
programmed voltage, the supply will switch over to a voltage regulation mode and maintain
the load voltage at the programmed level until it is discharged.
The flexible design of the 802 allows the unit to be ordered with (L model) or without (S and
OEM model) the front panel controls and meters. Front panel controls are ideal in
applications where local control and read backs are necessary, such as R&D, laboratory
use and diagnostics. All front panel controls and indicator signals are available at the rear
panel remote control connector regardless which panel option (L, S, or OEM) is selected.
The unit is self-contained, requiring only AC power and appropriate controls. Several units
may be connected in parallel for higher power operation. There is no theoretical limit to the
number of units that may be paralleled. Typically one master unit and one or more slave or
OEM units may be used to obtain as much output power as necessary. The 802 is also
ideally suited to charge reservoir capacitors in resonant charging circuits where high rep
rates (several kilohertz) are required, such as in metal vapor lasers or solid-state
modulators.

7
83488001 Revision N
1.5. Continuous DC Operation
Although the 802 series has been designed for capacitor charging applications, they can
also be used as a continuous DC High Power Source for RF tubes such as klystrons,
TWTs, or other DC loads such as DC-DC converters. The DC option must be specified
when ordering, and the supply will be factory setup and tested with a continuous DC load.
When 802 supplies are operated in continuous DC applications it is often necessary to add
an external capacitor between the load and ground to improve the ripple performance of
the unit. Our online Application Note 505 describes operating capacitor charging supplies
in DC applications, and gives guidance in determining the size of any additional external
filter capacitance required. App Note 505 can be found at:
http://www.us.tdk-lambda.com/hp/pdfs/application%20notes/93008505rC.pdf
Consult the factory before connecting parallel units in continuous DC applications.

Documentation Manual Including -
Installation, check out, suggested remote interfaces and control circuits
10 ft (3m). Output cable is standard, other lengths are optional.
1.7. Safety Precautions
All 802 power supplies are designed to minimize the risk of fire or shock
hazard. This instrument received comprehensive mechanical and
electrical inspection prior to shipment. Nevertheless, certain safety
precautions must be observed. Only TECHNICALLY QUALIFIED
SERVICE PERSONNEL familiar with the principles of electrical safety

c) Check front panel meters and LEDs for any broken or cracked lenses.
If any damage is found, follow the instructions in Section 3.3.
3.2. Electrical Inspection
Before the power supply is installed in a system, verify that no internal damage occurred
during shipping. A set of simple preliminary electrical test can be performed if desired. These
tests are described below.
NOTE
The sequences described are for L model supplies with local controls, for S and OEM
models the corresponding signals must be applied and monitored through the remote control
interface.
3.2.1. Test 1
Purpose: Verify general logic operation, generate maximum output current, and check
overload protection circuits. With AC power "OFF" and disconnected, short the HV
output by connecting the center conductor of the output cable to its return shield
(braid). This dead short will allow the unit to generate full output current at zero voltage.
1. Set the output voltage control to zero. Connect AC power to the unit. Turn "ON" the
AC power front panel switch.
2. Turn the front panel keyswitch to the LOCAL position (if applicable). Press the HV
"ON" button and turn up the HV control until the power supply is generating output
current into the dead short. The current meter will indicate max. current. The
voltage meter will read zero and the power supply will intermittently turn on and off
indicating the "overload" condition. The unit should continue to indefinitely cycle in
this mode with a 1 second period. (The power supply will go into overload when
max. current is drawn for more than half a second). If the LP option is installed, the
unit will shut down and indicate a fault after delivering full current for 500milliS.
3. Turn off the HV and AC power switches.
This test indicates the inverter section is generating maximum current and the logic and
overload circuitry works correctly.
3.2.2. Test 2
Purpose: Verify that the power supply generates maximum rated voltage, and the
regulation and feedback circuits are functioning.
1. With AC power OFF and disconnected, connect an appropriate load capacitor to
the power supply output cable. Select the capacitor size so the charge time is
several milliseconds or more.
2. Prepare to charge the capacitor. NOTE: Operating a 802 power supply into an open
circuit (no load operation) will instantly damage the power supply's HV output

diodes. Make sure the load (capacitor) is connected and the HV output cable is
securely inserted and connected.
3. Turn the voltage control on the front panel all the way down to zero (counter
clockwise), apply AC power, turn the front panel keyswitch to the LOCAL position (if
applicable), and press the HV ON button. By turning up the HV control knob the
capacitor will charge to the voltage indicated on the front panel voltmeter. The
power supply may be turned all the way up to its max. output voltage provided the
load capacitor is sufficiently rated.
4. By turning the voltage control down or depressing the HV OFF button, the capacitor
will slowly "bleed" down through the internal voltage divider resistors used for
regulation feedback. Use an external discharge wand to ensure the capacitor is fully
discharged.
Test #2 indicates the HV section is working correctly. Tests 1 and 2 generally indicate
the unit is functioning as designed. Although 100% power had not been generated,
these two tests give greater than 90% confidence that the unit is not damaged.
If any inconsistency from the above test procedure is noted, do not hesitate to call TDK-
Lambda Americas Customer Service for assistance.
3.3. Contacting TDK-Lambda Americas Customer Service
When contacting customer service locate the product description, part number and serial
number from the label located on the rear of the unit, and have this information available.
Phone: [phone] E-mail: [e-mail]
Fax: [phone]
Customer Service, or an approved Service Center, should be contacted if:
The power supply is mechanically or electrically damaged.
The power supply requires on-site calibration, or replacement warning decals.
The customer has questions about a special application that is not described in this
manual.
Normally, the customer may NOT open any chassis covers that have a warranty seal.
Breaking a seal will void the warranty.
At the discretion of TDK-Lambda Americas, the customer may be granted permission to
break the warranty seal and open the chassis covers. Customer Service shall confirm the
permission by sending a replacement seal. Once the unit has been serviced, the customer
shall close the cover and apply the replacement seal adjacent to (not on top of) the broken
seal.
3.4. Returning Defective Units
If a unit needs to be returned to the factory for repair, the factory must first assign an RMA
number. Please complete and send the online RMA request form at http://www.us.tdk-
lambda.com/hp/RMA_request.htm and an RMA number will be assigned. Follow the return
instructions on the form or at http://www.us.tdk-lambda.com/hp/returns.htm.

4. INSTALLATION
4.1. 19-Inch Rack Mounting
This power supply is intended for mounting in a conventional 19-inch equipment rack. It’s
8.75 inch height makes it a “5U” size instrument. The rack should enclose the sides, top and
back to protect the operator from electrical shock and protect the supply from environmental
contamination.
Never install the 802 so its weight is supported only by the front panel
screws!
The 802 must never be installed without support in the back or sides of the unit. The 802
should be mounted on support rails or chassis slides –such as General Devices CTS-124- or
on a suitable shelf or supports inside the rack.
The mechanical outline of the 802 is shown in Figures1 through 3.
