Notes:

1.Derate linearly from 3.7A at 50 degree to 2.7A at 70 degree.

2.The stated voltage regulation may not be maintained in the presure of certain transmitted radio signals, Any change in regulation will fail within the limits in criteria B of BS.EN.61000-6-2:2001

3. After 10 minutes

4. applies to mod status D onwards. Generator de-rate may apply. Check with factory

5.any device connected to the analogue input must be fully floating (galvanically isolated from ground ),with an insulation strength of 500V ac

6. Non condensing
