TDK-Lambda
RDS Series (110VDC Input)
Instruction Manual
6-13.
Withstand Voltage
When testing withstand voltage, please connect each side terminals of input and output as follows.
This series is designed to withstand 2.0kVAC between input and output, input and (Protective Earth), and 100VAC between output and
CNT/TOG each for 1 minute. When testing withstand voltage, set current limit of the withstand voltage test equipment as shown below.
The applied voltage must be gradually increased from zero to the testing value and then gradually decreased after test.
When timer is used, the power supply may be damaged by high impulse voltage at timer switch on and off..
7. Mounting Method etc.
7-1. Mounting Directions
Mounting directions are as the picture shown below. Standard mounting is (A). However, the mounting as (B) & (C) is also available.
Do not mount using (D) - (E) method. Use RDS according to the derating curve area by mounting direction and ambient temperature.
Derating curve limitations are determined shown in the section 7-2.
(A) Standard (B) Laid (C) Upward (D) Downward (E) Opposite direction of (B)

7-2. Output Derating
Natural Convection or Air-Forced Cooling
Output derating value is based on that of 100% output power.
Please apply 80% output power as the derating curve when the input voltage range is 143 to 160V.
