1. Introduction and specifications
1.1. General introduction
The System 9700 is a DC constant current output power supply designed for applications
requiring very high stability and low noise combined with reliability and ease of operation.
The System 9700 is conceived as a general-purpose scalable power supply for multiple magnet
configurations.
This MPS belongs to a new generation of high performance power converters suitable for many
high current and voltage applications where size and cost are of importance.
 Power range of 3 kW, 75 kW, allowing the user to select the most suitable solution.
 10ppm stability class using LEM Ultrastab high precision DCCT current transducer to
control the current stability in the power supply.
 Wide current range from 50 A to 1600 A.
 Remote controlled through a serial interface “RS232/RS422/RS485”.

1.3. Warranty and disclaimer
DANFYSIK A/S warrants that the products manufactured by us will be free from defects in
material and workmanship that would adversely affect the normal functioning of the unit for a
period of 18 months from the date of shipment or 12 months from the date of installation
whichever occurs first.
The exceptions to this are:
a) Parts not manufactured by DANFYSIK A/S which are covered by the original
equipment manufacturer's warranty.
b) Repair work, which is warranted for six (6) months from the date of shipment from the
DANFYSIK works.
DANFYSIK A/S will repair or replace either on site or at the factory and without charge, any
equipment that proves to be defective within its warranty period.
In the case of warranty, DANFYSIK A/S will pay or reimburse lowest freight rate (two-way) of
any item returned to DANFYSIK or our designated agent/representative, provided that prior
written authorisation for such return has been given by DANFYSIK A/S.
This warranty shall not apply to any equipment that has become defective or unworkable due
to mishandling, improper maintenance, incorrect use, radiation damage or any other
circumstance not generally acceptable for equipment of a similar type.
On standard products, DANFYSIK A/S reserves the right to make changes in design without
incurring any obligation to modify previously manufactured units.
The foregoing is the full extent of this warranty, and no other warranty is expressed or implied.
In no event shall Danfysik be liable for special damages arising from the delivery, late delivery
or use of the equipment.
If any fault develops, the following steps should be taken:
Notify DANFYSIK A/S, providing full details of the problems, and include model type and serial
number.
On receipt of this information, DANFYSIK A/S will give you either service information or
instructions for shipping.
All shipments of DANFYSIK equipment should be made according to our instructions and
shipped in the original or a similar container.
For smaller parts, a carton will be sufficient, if the parts are wrapped in ESD bags and
surrounded with at least 10 centimetres of shock absorbing material.

2. Unpacking and installation
2.1. Receiving the goods
The shipping container and the power supply should be thoroughly inspected for signs of
obvious physical damage immediately upon receipt.
All materials in the container should be checked against the enclosed packing list.
DANFYSIK A/S will not be responsible for shortages against the packing list unless notified
immediately.
2.2. Instructions for unpacking
The power supply is shipped in reinforced cardboard.
If the equipment is damaged in any way, a claim should be filed with the shipping agent, and a
full report of the damage should be forwarded to DANFYSIK A/S or our local
agent/representative immediately.
Upon receipt of this report, you will be issued instructions for the repair, replacement or return
shipment.
Please include the model no., type no., serial no., and order no. of the power supply on any
communication with DANFYSIK A/S or our representative.
2.3. Installation requirements
During installation of the Power Supply, local rules and regulations for electric power and water
supplies should be respected and the following conditions and installations should be available.
 A normal, dust free room with a humidity not above 80 % and a room temperature within
15 to 40 centigrade.
 Three phase Mains voltage switched and fused, + neutral and protective earth.
 Ground connection according to the local authority regulation and the requirements for the
equipment.
 If applicable, cooling water supply at a temperature within 15° to 35° Celsius.
Differential pressure: Min. 3 bar.
Inlet pressure: Max. 12 bar.
Please see specification sheet chapter 1.2 in this manual for actual figures for this power
supply.
 For cooling of our power supplies and magnets, we recommend the use of demineralized
water or pure water with an electrical conductivity of less than 10μS/cm. This reduces the
electrolytic corrosion to a minimum.
Adding pure ethylene glycol to the cooling water with no other additives should not affect the
electrolytic corrosion. However, it will reduce the thermal conductivity of the coolant. A
percentage of 40% glycol reduces the conductivity by approx. 30%. It is recommended to use
no more than 25% glycol corresponding to a reduction of thermal conductivity by approx. 17%.
It may be necessary to increase the water flow in the MPS.

Page 10 of 56
No other additives should be used.
During operation, the conductivity of the coolant should be checked regularly. A few days
operation with water of poor quality can cause more corrosion damage than during several
years’ operation with good quality water.
