5V Auxiliary supply.
This is available for powering auxiliary circuits and is present when AC input is applied regardless of inhibit/enable state of the
PSU outputs. The output is rated as SELV.
Output voltage 5V +/- 5% (Option E, F, EV, FV) or 5-15V (Option xEW, xFW)
Max continuous output current 100 mA (Option E, F) or 300mA (Option EV, FV) or 1A (Option xEW, xFW)
Overload protection Current limited and thermally protected
Hold up time 1 Sec minimum
Isolation to earth 500V DC max
