Fan cooling
Remarks:
[1] Specifications are for one hour warm-up and at 25℃.
[2] The maximum time required for regulating corresponding output when received APPLy and
SOURce commands.
[3] The variation of output within 8 hours after warm-up 30 minutes and both the load circuit and
environment temperature are in constant conditions.
