Ordering Information：
- x = blank stands for Remote On/Off Logic Positive
x = N stands for Remote On/Off Logic Negative
y = blank stands for M3.5x0.5 mounting inserts
y = C stands for Clear mounting insert (3.2mm DIA)
z = blank stands for -40~105℃ operating temp.
z = L stands for -55~105℃ operating temp. - Nominal input voltage 300VDC.
Measured at nominal input voltage. - An external input capacitor 33uF for all models are recommended to reduce input ripple voltage.
- -55°C start-up screen per MIL-STD105E S1 Sampling Procedure for L Version.
