1. x = blank stands for Remote On/Off Logic Negative
   x = P stands for Remote On/Off Logic Positive
2. Nominal Input Voltage 24, 48VDC.
   Measured at Nominal Input Voltage.
   Measured at 12VDC for 24Vin, 24VDC for 48Vin.
3. The output terminal of 5V Vout models required a minimum capacitor 680uF to maintain specified regulation.
   The output terminal of 12/24/28V Vout models required a minimum capacitor 330uF to maintain specified regulation.
   The output terminal of 48V Vout models required a minimum capacitor 100uF to maintain specified regulation.
4. An external input capacitor 1000uF for 24Vin or 330uF for 48Vin models are recommeded to reduce input ripple voltage.
5. If the remote sense feature is not to be used, the +sense pin should be connectoed to the +Vout pin and the -sense pin should be connected to the -Vout pin.
