SECTION I – INTRODUCTION/SPECIFICATIONS
1.0 SCOPE OF MANUAL
This manual is provided to assist the user in the installation and operation of the Bertan
Series 602C, 603C, 605C, 606C and 612C modular high voltage power supplies. Statements
will apply to models in all of 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 602C, 603C, 605C, 606C and 612C are families of regulated fixed output polarity
modular high voltage power supplies. They provide exceptional performance in applications
such as CRT’s spectrometers, detectors, medical imaging, image intensifiers, E-Beam, I-
Beam, medical imaging and capillary electrophoresis (HPCE) systems.
1.2 DESCRIPTION
The units are fully enclosed and designed to easily satisfy system or bench top operation. A
wide range of stable output voltages, up to 30kV are available. The output voltage is
controlled locally by a minimum 15-turn potentiometer. Remote analog voltage of resistance
programming is also available to the user as a standard feature. All units offer a 0 to +5Vdc
analog monitor output proportional to the output current.
The Series 602C, 603C and 612C require an input of 115/230Vac (switch selectable) +10%,
50-60Hz. The Series 605C and 606C require a +28Vdc +10% input (or +24Vdc ±10% for
units equipped with +24V Option). Each unit in the Series converts the applied power to a
high voltage DC output. This output voltage is highly regulated and filtered. The high voltage
assembly is fully encapsulated in silicone rubber for reliable, arc-free, stable operation.

SECTION II – OPERATION
CAUTION: THIS UNIT CAN STORE HAZARDOUS VOLTAGE! COMPLETELY DISCHARGE
THE HIGH VOLTAGE TO GROUND BEFORE ATTEMPTING REMOVAL OF THE
HIGH VOLTAGE CABLE.
2.1 INSTALLATION
All power supplies can be mounted in any position using the tapped holes in the base plate.
The mounting screws should extend no more than ¼” into the unit. Series 602C and 605C
require #8-32 mounting screws. Series 603C, 606C, and 612C require #10-32 mounting
screws.
2.2 INPUT POWER
Input power is applied via the 3-terminal terminal strip for the Series 602C, 603C, and 612C or
via the 9-pin connector for the Series 605C and 606C. The terminal or pin connections are as
listed in Section 2.7.
CAUTION: APPLICATION OF INPUT POWER CAN IMMEDIATELY PRODUCE A HIGH
VOLTAGE OUTPUT!
2.3 HIGH VOLTAGE CONTROL
There are three modes of controlling the high voltage. The use can select mode by making
appropriate connections via the 9-pin Molex connector. All modes provide high voltage control
from 0 to 100% (±0.5%).
2.3.1 INTERNAL POTENTIOMETER CONTROL
See Section 2.7 for hook-up information. This will allow control of the high voltage output by
means of the multi-turn potentiometer accessible via a hole in the cover.
2.3.2 EXTERNAL POTENTIOIMETER CONTROL
See Section 2.7 for hook-up information. Connecting an external potentiometer
(recommended value of 5kΩ) will control the high voltage output independently of the internal
potentiometer setting.
2.3.3 EXTERNAL VOLTAGE CONTROL
See Section 2.7 for hook-up information. The output high voltage can be controlled by a 0 to
+5Vdc analog signal.
2.4 HIGH VOLTAGE MONITOR
See Section 2.7 for hook-up information. A 0 to +5Vdc analog signal which is proportional to
the output high voltage. The monitor has a series impedance of 10kΩ.
2.5 OUTPUT CURRENT MONITOR
See Section 2.7 for hook-up information. A 0 to +5Vdc analog signal which is proportional to
the output current. The monitor has a series impedance of 10kΩ.

SECTION III PROGRAMMING OPTIONS
3.1 GENERAL
To provide additional flexibility and compatibility with earlier models, provision has been
included to allow voltage programming of all models with a 0 to –5 Volt programming input.
There are four different jumper-selectable modes for programming. The jumpers for selecting
the required operating mode are located on PCB100 (the large PCB), easily accessible upon
removal of the cover. Jumper locations are shown below in Table III-1.
The four modes are described below. The first three modes apply to all Series 602C, 603C,
605C, 606C and 612C units. The last mode applies only to the Series 612C and is included
only with Series 612C units ordered with the –5VPRO option.
3.2 STANDARD MODE
The unit is shipped in this configuration and operation is as described in the previous sections
of this instruction manual. The unit can be controlled using the internal pot or programmed
with a remote 0 to +5 Volt signal or controlled with a remote potentiometer.
3.3 -5 VOLT PROGRAMMING (for 0 to 100% output voltage) MODE
To achieve this operation the jumpers on PCB100 must be configured as shown in the chart
below. In this mode the programming signal is applied to P2 pin 4, same as for Standard
Mode, only now a 0 to –5 Volt programming input is required to achieve 0 to 100% output
voltage programming. No jumpers should be attached to P2, the external connector. In this
mode there is no internal control, the internal potentiometer is bypassed.
3.4 -5 VOLT PROGRAMMING (for 0 to 103% output voltage) MODE:
To achieve this operation the jumpers on PCB100 must be configured as shown in the chart
below. In this mode the programming signal is applied to P2 pin 4, same as for Standard
Mode. No jumpers should be attached to P2, the external connector.
In this mode the internal potentiometer is used to control the maximum programmed output
voltage at –5 Volt programming input. With the potentiometer fully clockwise, the output will be
0 to 103% of maximum for a 0 to –5 Volt input. With the potentiometer turned up
approximately half way, a 0 to –5 Volt input will produce a 0 to approximately 50% of maximum
output voltage.
This mode is included to provide exact compatibility with some previous units. It also provides
the user with a controllable upper limit on the programmed output for an input of –5 Volts.

9
3.5 SERIES 612C –5 VOLT PROGRAMMING MODE
Series 612C units ordered with the –5VPRO (-5 Volt Programming) option, include an extra 5
pin hexaganol connector (J3). The connector contains additional monitor outputs and a 0 to –
5 Volt programming input. This option provides compatibility with earlier Series 612C models
when used with –5 Volt programming. The mating connector for J3 is included and J3
connections are shown below in Table III-2.
In this mode the programming signal is applied to J3 pin A. A 0 to –5Volt programming input is
required to achieve 0 to 100% output voltage programming. No jumpers should be attached to
P2, the external connector. In this mode there is no internal control, the internal potentiometer
is bypassed.

SECTION IV – CIRCUIT DESCRIPTION
4.1 FUNCTIONAL DESCRIPTION
The 602C, 603C, and 612C employ a standard stepdown transformer to obtain a nominal
+28Vdc from the input ac power. The Series 605C and 606C obtain +28Vdc (+24Vdc for +24V
Option models) from the input ac power. The circuit converts the +Vdc low voltage input
DC power to a high voltage DC output. This output voltage is highly regulated and filtered
and can be varied either by the local potentiometer control or through the REMOTE
PROGRAM input.
An oscillator determines the frequency (approximately 20kHz) at which all amplification, high
voltage transformation, rectification and filtering occurs. The amplification is a function of a
control voltage which performs the function of control and regulation. A sample of the output
voltage is compared against a reference voltage in the sensing circuit. The sensing circuit
generates the control voltage to set and maintain a fixed high voltage output.
The encapsulated high voltage assembly includes a high voltage power transformer, rectifier or
multiplier circuits, ripple filter and sensing circuits. These are all critical, custom designed and
encapsulated components.
SECTION V – MAINTENANCE
5.1 GENERAL
The high voltage power supply should not require any maintenance or calibration. It is
designed for reliable, trouble free operation. If any question should arise, contact the Bertan
Customer Service Department for assistance or return authorization. Although it is felt
that adequate information is provided in this manual, it is suggested that the unit be returned
to the factory is service should become necessary.
The power supply can be returned to the factory for annual calibration and certification to its
original specification. For traceability, a certificate will be issued, indentifying the serial number
of the unit calibrated and all test equipment used to perform the calibration. All measurements
are traceable to the National Institute of Standards and Technology (N.I.S.T.). Contact the
factory for additional details.
5.2 CLEANING
Cleaning of the power supply shouldonly be performed with the supply disconnected from the
ac power source. A soft cloth moistened with conventional ammonia-based cleaning agents
will suffice for all exposed surfaces. The exposed shell of the HV connector should be cleaned
with isopropyl alcohol.
If the supply is operated in a dusty environment, an accumulation of dust/debris may build-up
inside the unit which may cause noisy operation (i.e., “ticking” or minor crackling) in the area of
the HV cabling on the 10kV through 30kV models. The safest way to remove such debris is
with compressed air. Ensure that no dust/debris is left behind in the insulative medium of the
HV output connector after this cleaning operation. Such dust may be removed with a cotton
swab moistened with isopropyl alcohol.
