*1 The performance values are based on IEC 60068-3-5:2001, JTM K07:2007 for the temperature chamber. Performance fi gures are given for a ＋23℃ ambient temperature,
65%rh, rated power supply and no specimens inside the test area. However, the lowest attainable temperature is given for a max. ambient temperature of ＋30 ℃.
Heat-up time is the achieved time from lowest temperature to highest temperature within temperature range.
*2 Excluding protrusions.
*3 At ambient temperature ＋23℃. For SU-641/661, make sure to check the power capability of your installation beforehand.
*4 Compliance with CE Marking.
*5 Measurements are to be taken in an anechoic room at a height of 1.2m from the fl oor and a distance of 1m from the chamber front panel
(ISO 1996-1:2003 _ A-weighted sound pressure level)
