1. In case of No Output - what to check
2. In case of Abnormal Output Voltage(Too High, Too Low, Unstable) - what to check

2. In case of Abnormal Output Voltage(Too High, Too Low, Unstable) - what to check

When output voltage is unstable.
Check PointsSolutionsApplicable Products
There is oscillation caused by remote sensing. - 1
Are the sensing wires too long?		 Use electrolytic capacitor between output terminal (±V, ±M) and sensing terminal (±S). R150U,
P100E-P(T)1500,
UAW, UAF,
LDA300,
PAA100F-PAA600F
There is oscillation caused by remote sensing. - 2
Are the sensing wires twisted?		 Twist the wires.
Minimum output current required is not drawn.
In case of some Multiple output type power supply, a minimum drawing current is required on +5V output.
Check to see if there is minimum load requirement for the power supply.		 (1)Draw a minimum current required on +5V.
(2)Use a power supply whose +5V output has no minimum drawing current requirement. 		1)PMC, MMC
2)MMB, LEB,RMB, RMC,LDC
