RID-125 Series - 125W Dual Isolated Output Enclosed Power Supply



RID-125 series are AC/DC switching power supplies that can provide 125W using air convection. RID-125 series can withstand 300VAC input surge for 5 seconds and 5G vibration that is suitable to be operated in harsh environment. The isolated design between CH1 and CH2 can significantly prevent noise sourcing from the motor action from entering control circuits and hence secure the accurate operation of the end equipment. Other standard functions include short circuit, overload, and over voltage protections.
