Section 1  
Introduction  
1.1 General Description  
The 960PS Power Supply is used to supply power to the modules that are plugged into the  
960MB/961MB motherboards.  
The power supply is mounted outside of the 960CC Card Cage Module, the wall mounted Local Control  
Unit enclosure, or control room cabinet. The input AC voltage is soft started to inhibit current surges when  
powered up. EMI protection is also provided as part of the AC voltage protection. The power supply has  
remote error sensing and short circuit/overload protection along with input and output over-voltage  
protection. See Figure 1-1, the Power Supply Functional Block Diagram.  
1.2 Application  
The 960PS-200 & 960PS-210 Power Supply Modules are used in VICTOREEN series area monitors,  
process monitors, isolators, control rooms, and safety-related display cabinets.

1.5 Installation  
The 960PS-200 and 960PS-210 Power Supply Modules are supplied as part of a radiation monitoring  
system (RMS) or as replacement parts for an existing RMS. When the power supplies are shipped as part  
of a system, they are installed at the factory.  
When a module is shipped as a replacement part, verify the integrity of the gasket, heat sink, and seal  
screw fasteners (when used) prior to installation. Apply P/N 88-10 thermal coat, or equal heat transfer  
compound between power supply and heat sink to ensure the thermal coupling of the installed power  
supply. For operation of the 960PS-210 at 220 VAC, verify the location of the internal supply voltage  
jumper E1. The part number of the required mounting hardware may be found in the system assembly  
drawing section of the applicable systems manual.  
1.6 Procedures, Warnings, and Cautions  
The equipment described in this manual is intended to be used for the detection and measurement of  
ionizing radiation. It should be used only by persons who have been trained in the proper interpretation of  
its readings and the appropriate safety procedures to be followed in the presence of radiation.  
Although the equipment described in this manual is designed and manufactured in compliance with all  
applicable safety standards, certain hazards are inherent in the use of electronic and radiometric  
equipment.  
WARNINGS and CAUTIONS are presented throughout this document to alert the user to potentially  
hazardous situations. A WARNING is a precautionary message preceding an operation that has the  
potential to cause personal injury or death. A CAUTION is a precautionary message preceding an  
operation that has the potential to cause permanent damage to the equipment and/or loss of data. Failure  
to comply with WARNINGS and CAUTIONS is at the user's own risk and is sufficient cause to terminate  
the warranty agreement between Fluke Biomedical and the customer.  
Adequate warnings are included in this manual and on the product itself to cover hazards that may be  
encountered in normal use and servicing of this equipment. No other procedures are warranted by Fluke  
Biomedical. It shall be the owner's or user's responsibility to see to it that the procedures described here  
are meticulously followed, and especially that WARNINGS and CAUTIONS are heeded. Failure on the  
part of the owner or user in any way to follow the prescribed procedures shall absolve Fluke Biomedical  
and its agents from any resulting liability.  
Indicated battery and other operational tests must be performed prior to each use to assure that the  
instrument is functioning properly. If applicable, failure to conduct periodic performance tests in  
accordance with ANSI N323-1978 (R1983) Radiation Protection Instrumentation Test and Calibration,  
paragraphs 4.6 and 5.4, and to keep records thereof in accordance with paragraph 4.5 of the same  
standard, could result in erroneous readings or potential danger. ANSI N323-1978 becomes, by this  
reference, a part of this operating procedure.

Operation  
960PS-200 Power Supply

Section 2  
Operation  
2.1 960PS-200 Power Supply  
The 960PS-200 supplies three different DC voltage outputs to the 960 modules through the  
960MB/961MB motherboard. 115 VAC is connected to terminal strip A3, part of the front panel. The AC  
line voltage is fed to a bridge rectifier circuit and rectified by diodes CR1, CR2, CR3, and CR4. A  
thermistor is connected in series with the incoming AC voltage to decrease the effect of "turn-on" in-rush  
current to the power supply. For all practical purposes this is a soft start device. On some models of the  
power supply a current limiting resistor is used rather than a thermistor. Refer to schematic drawing  
960PS-200-53  
2.2 Input Filter  
The rectified voltage from the bridge goes to a filter network made up of inductor L1 and a capacitor C1.  
This filter removes the DC voltage line ripple resulting from the rectification process.  
2.3 DC to DC Converter  
The voltage is supplied to a DC to DC converter circuit. The converter has an oscillator circuit, with its  
transformer and transistors, converts the DC voltage to a high frequency AC voltage. Transformer T1 has  
the oscillator Q1 in the primary and as part of the secondary a feed back winding. The purpose of the  
feed back winding is maintaining oscillations independent of circuit loading. There are three outputs on  
T1's secondary that provide the source voltage for the power supply output voltage.  
The output from T1 at pin 7 is rectified to DC by CR1 and CR2 and fed through another filter circuit. The  
output goes to two zener diodes VR1 and VR2. The zener diodes regulate the voltage down to 15 V. The  
15 V is supplied to the circuits in the power supply.  
2.4 Voltage Regulation  
One of the zener diodes, VR2, regulates the voltage that is used in the 5 V and short circuit/overload  
protection circuit. Operational amplifier AR1 acts as a voltage regulator by comparing the voltage output  
to a reference 5 volts. The output 5 V is fed to terminal strip A3.  
An output is also fed to the -15 V and +15 V circuits. These two circuits function much the same as the +5  
V. The only difference is that the +5 V circuit is the primary output circuit and it controls all the other  
secondary circuits. In addition to this only the +5 V circuit has protection.

2.5 960PS-210 Power Supply  
The 960PS-210 Power Supply is similar in operation to the 960PS-200, with the exception that it  
incorporates an additional 24 VDC output, an input voltage sensing circuit, and a common and differential  
mode choke. Refer to schematic drawing 960PS-210-53.

Maintenance  
Section 3  
Maintenance, Calibration and Troubleshooting  
3.1 Maintenance  
No periodic maintenance is required for the module. The output voltage levels, however, should be  
verified periodically.  
NOTE  
If a maintenance question arises and cannot be  
resolved by using this manual, please contact Fluke  
Biomedical at 440.248.9300.  
3.2 Calibration  
There are no user adjustments on the main 960PS-200. Should the output voltage fall outside of the  
tolerance specified, the unit must be returned to Fluke Biomedical for repair.  
Adjustments to the 960PS-210 are limited to the AC Line Monitor Voltage trip point adjustment (R40),  
mounted on the stand-up circuit board, and the +5 VDC output voltage adjustment (R17). Adjustments to  
sealed potentiometers; R16 (FREQ.), R27 (CURR.), and R28 (OUP.) should be performed only by  
factory-trained technicians. Should the output voltage fall outside of the tolerance specified, the unit must  
be returned to Fluke Biomedical for repair.  
3.3 Troubleshooting  
WARNING  
Extreme care must be used when troubleshooting a  
system that has power applied. All standard  
troubleshooting precautions apply.  
WARNING  
Once a problem has been located, remove all  
power before continuing with the repair.  
CAUTION  
Personnel performing the following procedure must  
be familiar with the operation of the monitoring  
system and the location of each piece of equipment  
used in the system.

Victoreen 960PS-200 & 960PS-210  
Operators Manual  
If a problem develops, verify that the voltages at connection point inputs and outputs are present and that  
all wiring is secure. Ensure fuse F1 is not open for the 960PS-210 Power Supply. Refer to Appendix B for  
drawings.  
The 960PS-200 and 960PS-210 Power Supply Modules must be returned to the factory for service if  
troubleshooting of the module is necessary.
