Xantrex Technology 18V 10A Benutzerhandbuch

  

The outputs of the power supply are fully floating and may be used in series with other power 
supply units to generate high DC voltages up to 300V DC. 

The maximum permissible voltage between any terminal and earth ground (

) is 300VDC. 

WARNING! Such voltages are exceedingly hazardous and great care should be taken to shield 
the output terminals for such use. On no account should the output terminals be touched when 
the unit is switched on under such use. All connections to the terminals must be made with the 
power switched off on all units. 

It should be noted that the unit can only source current and cannot sink it, thus units cannot be 
series connected in anti-phase. 

The unit can be connected in parallel with others to produce higher currents. Where several units 
are connected in parallel, the output voltage will be equal to that of the unit with the highest output 
voltage setting until the current drawn exceeds its current limit setting, upon which the output will 
fall to that of the next highest setting, and so on. In constant current mode, units can be 
connected in parallel to provide a current equal to the sum of the current limit settings. 

Note that the output terminals are rated at 15A maximum; if several outputs are operated in 
parallel to source higher currents than this the junction should be made at a separate point, not 
one of the terminals. 

The power supply is very efficient but nevertheless can generate significant heat at full power. 
The supply relies on convection cooling only and it is therefore important that ventilation is never 
restricted if performance and safety are to be maintained. 

Maintenance 

The Manufacturers or their agents overseas will provide repair for any unit developing a fault. 
Where owner wish to undertake their own maintenance work, this should only be done by skilled 
personnel in conjunction with the service manual which may be purchased directly from the 
Manufacturers or their agents overseas. 

The correct fuse type is: 

10 Amp 250V HBC time-lag(T), 5 x 20mm. 

Note that the main function of the fuse is to make the instrument safe and limit damage in the 
event of failure of one of the switching devices. If a fuse fails it is therefore very likely that the 
replacement will also blow, because the supply has developed a fault; in such circumstances the 
instrument will need to be returned to the manufacturer for service. 

Make sure that only fuses of the required rated current and specified type are used for 
replacement. The use of makeshift fuses and the short-circuiting of fuse-holders is prohibited. 

To replace a fuse, first disconnect the instrument from the AC supply. Remove the 6 cover 
securing screws and lift off the cover. Replace the fuse with one of the correct type and refit the 
cover. 

If the PSU requires cleaning use a cloth that is only lightly dampened with water or a mild 
detergent. Polish the display window with a soft dry cloth.
