Notices:
- x = blank stands for Remote On/Off Logic Negative
x = P stands for Remote On/Off Logic Positive - Nominal Input Voltage 24, 48VDC.
Measured at Nominal Input Voltage.
Measured at 12VDC for 24Vin, 24VDC for 48Vin. - 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. - An external input capacitor 1000uF for 24Vin or 330uF for 48Vin models are recommeded to reduce input ripple voltage.
- 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.
