Notices：
- x = blank stands for Remote On/Off Logic Negative
x = P stands for Remote On/Off Logic Positive - Nominal Input Voltage 24VDC.
- An external input capacitor 220uF for all models are recommeded to reduce input ripple voltage.
- The output terminal required a minimum capacitor 470uF to maintain specified regulation.
