Important notes:
1. The electrical mains lead should be certied for in the country of use and when applicable the plug must
be tted with a 240 V 5A fuse
2. If users use any other power supply, they do so at their own risk
3. The SW4189 is for use with telecommunications, computer, industrial controllers & OA systems, and
must only be used indoors
4. The PS-90 is the only external power supply recommended for use with the New iStar camera. If this unit
fails or is damaged, the local Andor representative should be contacted for a replacement.
2.10 - POWER SUPPLY UNIT (PSU)
The New iStar system is designed to be powered from an SW4189 external PSU (Andor P/N PS-90) as shown below.
This requires an AC mains input between 100-240 V, 47-63 Hz and a maximum supply current of 1.6A. The output of the
SW4189 is 12V DC at 9.0A maximum. The SW4189 PSU is tted with an IEC connector for the electrical supply input.
The connection to the New iStar is made via a 3 pin Redel cable plug (Part No. PAH.N0.3GL.LC65GZ).
2.11 - FUSE REPLACEMENT
The camera itself does not have a fuse. However, if a U.K. (BS 1363) mains lead has been supplied, it contains a fuse,
whose characteristics are as follows:
