black plastic package in a 9-pin SIL compatible case with high performance features such as 1500 VDC input/output isolation voltage,
continuous short circuit protection with automatic restart and high line / load regulation. Wide range devices operate over 4:1 input voltage
range providing stable output voltage. Devices are encapsulated using flame retardant resin. Input voltages of 24 and 48 with output
voltage of 3.3, 5, 12, 15,±5,±12,±15 Vdc. High performance features include high efficiency operation up to 85% and output voltage
accuracy of ±1% maximum.

NOTE
NOTE
1. Operation at no load condition will not damage the product ; however, it will not meet all specifications.
2. One load is 25% to 100% load, the other load is 100% load, the output voltage variable rate is within ±5%.
3. Operation at lower load and no load may have bigger ripple and noise.
4. Test by minimal Vin and constant resistive load.
5. Test by normal Vin and 100%-25% load,25% Ioad step change;If the output voltage is 3.3V then the Transient Response Deviation is ±5%.
6. Measured Input reflected ripple current with a simulated source inductance of 12uH and a source capacitor Cin(47uF, ESR<1.0Ω at 100KHz).
7. Exceeding the absolute ratings of the unit could cause damage. It's not allowed for continuous operating ratings.
8. Input filter components are be required to help meet conducted emission class A,
which application refer to the EMI Filter of design & feature configuration.
9. An external filter capacitor is required if the module has to meet IEC61000-4-4 and IEC61000-4-5.
The filter capacitor Motien suggest: Nippon - chemi - con KY series, 220uF/100V.

NOTE
TEST CONFIGURATIONS
Input Reflected Ripple Current Test Step
Output Ripple & Noise Measurement Test
Input reflected ripple current is measured through
a source inductor Lin(12uH) and a source capacitor
Cin(47uF, ESR<1.0Ω at 100KHz) at nominal input and
full load.
The Scope measurement bandwidth is 20MHz.
