(*1) At Ta=25℃ and maximum output power.
(*2) For cases where conformance to various safety specs (UL, CSA, EN) are required,input voltage range will be 100 - 240VAC (50/60Hz).
(*3) First in-rush current. Not applicable to the first 0.2ms in-rush current flowing into the power supply noise filter.
(*4) Measure with JEITA RC-9131A probe, bandwidth of scope: 100MHz.
(at 100uF electric capacitor and 0.47uF film capacitor on the test fixture board.)
Ripple noise spec for ambient temperature between -10 to 25 is a linearity value with respect to the -10 degrees
C and 25 degrees C specs.
(*5) 85 - 265VAC, constant load.
(*6) No load-Full load, constant input voltage.
(*7) Constant current limit with automatic recovery. Over current condition for more than 5 seconds will cause the out-
put to shutdown. Output current exceeding maximum rated output current for more then 10 seconds continuously
will result to output shutdown.
(*8) OVP circuit will shut down output, manual reset (power cycle) or ON/OFF CNT signal reset.
(*9) At 100/200VAC, nominal output voltage and maximum output current.
(*10) Measured by the each measuring method of UL, CSA, EN and DENAN (at 60Hz), Ta=25 .
(*11) Ratings - Derating at standard mounting.
- Load (%) is percent of maximum output power or maximum output current, whichever is greater.
- As for other mountings, refer to derating curve.
(*12) As for DENAN, built to meet at 100VAC.
(*13) Peak output current is less than 10 seconds, and duty 35% max. (200VAC Line only)

3) Output voltage becomes more stable by performing the following.
a) Electrolytic capacitor is added to an output.
+3.3V,+5V,+6V : LXZ 10V 5600uF (NIPPON CHEMI-CON) x 3 parallel
+7.5V : LXZ 16V 3900uF (NIPPON CHEMI-CON) x 3 parallel
+12V : LXZ 25V 2700uF (NIPPON CHEMI-CON) x3 parallel
+15V : LXZ 25V 2700uF (NIPPON CHEMI-CON) x3 parallel
+24V : LXZ 35V 1800uF (NIPPON CHEMI-CON) x3 parallel
+36V : LXZ 50V 1000uF (NIPPON CHEMI-CON) x3 parallel
+48V : LXZ 63V 820uF (NIPPON CHEMI-CON) x3 parallel
+60V : LXV 100V 270uF (NIPPON CHEMI-CON) x 3 parallel
b) Remote sensing function is used.
Connect "+S" terminal to "+" terminal of the electrolytic capacitor
and "-S" terminal to "-" terminal of the electrolytic capacitor with sensing wires.

operation or application of our products. It does not imply any guarantee or granting of license for intellectual
property rights or other rights held either by TDK-Lambda Corporation or third parties. TDK-Lambda Corporation does
