PROPERLY CONNECTED.

boards. The high voltage assembly is fully
encapsulated in silicone rubber for reliable, arc­free, stable operation.

SECTION II: OPERATION

THE DATA CONTAINED IN THIS MANUAL IS
SUBJECT TO CHANGE WITHOUT NOTICE.
WRITTEN PERMISSION FROM SPELLMAN HIGH
VOLTAGE IS REQUIRED PRIOR TO THE
REPRODUCTION OF ANY TECHNICAL DATA
CONTAINED IN THIS MANUAL.

SECTION I: GENERAL DESCRIPTION

1.0 SCOPE OF MANUAL

This manual is provided to assist the user in the
installation and operation of the Spellman Series
205B rack-mountable high voltage power supplies.
Statements apply to all models in the Series unless
reference is made to specific models. For the
protection of personnel and equipment, it is
essential that this manual be thoroughly read prior
to the installation and application of power.

1.1 PURPOSE OF EQUIPMENT

The series 205B is a family of regulated precision
regulated, locally and remotely variable high
voltage power supplies. They offer exceptional
performance in such critical applications as nuclear
and electro-optical instrumentation, medical
imaging and capillary zone electrophoresis and
precision CRT displays.

1.2 DESCRIPTION

The units are fully enclosed and designed to mount
in a standard 19” rack. A wide range of stable
output voltages from 1kV up to 50 kV is available.
The output voltage is set either by front panel
controls or remote analog voltage or resistance
programming. Remote analog monitoring is
provided on all models.

Output polarity reversal is achieved by turning a
polarity switch on the rear panel of 1kV, 3kV and
5kV models. The 10kV and higher output models
have an internal polarity reversing assembly that is
easily accessible in the field. NOTE: in either case,
polarity reversal MUST ONLY BE DONE WHEN
THE HIGH VOLTAGE IS OFF.

CAUTION! THIS UNIT CAN STORE
HAZARDOUS VOLTAGE. COMPLETELY
DISCHARGE HIGH VOLTAGE AT REAR PANEL
GROUND TERMINAL BEFORE ATTEMPTING
REMOVAL OF THE HIGH VOLTAGE CABLE

2.1 INSTALLATION:

The 205B Series high voltage power supplies
mount in a standard 19” rack.

2.2 INPUT POWER

The input AC line voltage required is
115V/230VAC, ±10%, 50-400Hz, single phase.
The LINE VOLTAGE selector switch on the rear
panel MUST BE SET for either 115VAC or
230VAC BEFORE application of input power.

2.3 VOLTAGE CONTROL

The 205B Series power supply has two modes of
controlling the high voltage outputs available to the
user. Set the PROGRAM CONTROL switch
(S101) on the rear panel to LOCAL for front panel
control. For remote analog control, set the switch
to the REMOTE ANALOG position. The high
voltage output can then be remotely programmed
either from an external voltage source or by using
an external potentiometer. When S101 is in the
REMOTE ANALOG position, the front panel
controls will have no effect on the output voltage
setting.

At all times, regardless of the position of the rear
panel PROGRAM CONTROL switch, the user may
enable or disable the high voltage output by
switching the HV ENABLE switch on the front
panel. In addition, the voltage and current
monitors are always active. Thus, even when the
PROGRAM CONTROL switch is set to REMOTE
ANALOG control position, the front panel and the
remote analog monitors continue to make voltage
and current readings available.

2.4 POLARITY REVERSAL

The front panel LED display will indicate which
polarity the unit is set for. The display illuminates
even if there is no high voltage output.

The Series 205B units contain a DC power supply
that converts the AC line power to a low voltage DC
and a DC-to-DC converter that generates the high
DC voltage. Low voltage electronics solid-state
analog circuits are placed on plug–in printed circuit

205B Series User’s Manual 2 118124-001-Rev.A

CAUTION – LINE INPUT POWER MUST BE
TURNED OFF AND THE HIGH VOLTAGE
SHOULD BE DISCHARGED FULLY BEFORE
PROCEEDING TO REVERSE THE POLARITY.

2.4.1 POLARITY REVERSAL 1kV TO 5kV
OUTPUT MODELS

The screwdriver-rotatable POLARITY SELECTOR
switch (S3) is accessible at the rear panel of the
unit. Rotate as required for the desired polarity.

2.4.2 POLARITY REVERSAL 10kV TO 50kV
OUTPUT MODELS

The polarity is reversible by means of an internal
polarity module, which is easily accessible upon
removal of the top cover. Polarity is reversed by
removing two diagonally opposed Philips head
screws, lifting up on the module, rotating it 180°,
and then reinserting it. A safety interlock
automatically ensures that the high voltage cannot
be turned on unless this module is fully seated and
installed in one polarity position or the other.

3.2 PROGRAM CONTROL SWITCH

The front panel controls of the unit are only
functional for programming purposes when the
units’ rear panel PROGRAM CONTROL switch
(S101) is in the LOCAL position. However, if the
unit receives a voltage programming command
while S101 is in the Remote Analog position, the
switching of S101 to its LOCAL position afterwards
will then cause the value of that programming
command to take effect.

3.3 LOCAL OPERATION

The local mode of the 205B Series provides all of
the control and monitoring functions available with
front panel control.

A remote polarity indication is provided at J107
(PROGRAMMING/MONITOR) connector jack
located on the rear panel of the unit (see section

4.3).

4.1 PROGRAM CONTROL SWITCH

Before a unit can be programmed with a remote
analog (0 to +5VDC) signal, it must be configured
by setting its rear panel PROGRAM CONTROL
switch (S101) in the REMOTE ANALOG. Note:
All other monitoring and non-programming
functions remain active, regardless of the S102
position.

4.2 REMOTE CONTROL

The high voltage output can be remotely
programmed from an external voltage source. A 0
to +5VDC programming voltage applied to Pin 6 of
the J107 (PROGRAMMING/MONITOR) connector
jack on the rear panel will remotely program the
high voltage output from zero to maximum voltage.
