put voltage. They feature efficiency up to 91%, 1500VDC isolation, ope-
rating temperature of -40°C to +105°C, input under-voltage protection,
output over-voltage, output over-current, output short circuit protec-
tion and EMI meets CISPR32/EN55032 CLASS A.
-40°C to +105°C
Meet CISPR32/EN55032 CLASS
A, no external components
International standard pin-out
Wiring and rail mounting
products featuring anti-
reverse connection for input
Meets EN62368 standards
(pending)
They are widely applied in industrial control, electric power, instru-
ments and communication fields. Extension packages with wiring
mounting and rail mounting also enable them with reverse voltage pro-
tection.

15= 15Watt; D= DIP; M= series; W4= wide input (4:1); E= cost
effective; 9-36Vin; 15Vout; D= dual output; 1.5= 1500VDC
*
At 0%-5% load, the Max. output voltage accuracy converter is 5%.
** 0%-5% load ripple&noise is no more than 5%Vo.
Ripple and noise are measured by “parallel cable” method.
