E_XT-1WAR2 series are specially designed for applications where an isolated voltage is required in a distributed power supply system. They
are suitable for
1. Where the voltage of the input power supply is stable (voltage variation: ±10%Vin);
2. Where isolation between input and output is necessary (isolation voltage
≤3000VDC);
3. Where the output voltage regulation is not strictly required;
4. Typical application: preceding-stage interference isolation condition; ground-interference canceled condition; digit circuit condition;
Voltage-isolation converting condition; normal low-frequency artificial circuit condition; relay drive circuit condition, etc.

Design Reference
1. Typical application circuit
If it is required to further reduce input and output ripple, a filter capacitor may be connected to the input and output terminals, see Fig.3.
Moreover, choosing a suitable filter capacitor is very important, start-up problems may be caused if the capacitance is too large. Under the
condition of safe and reliable operation, the recommended capacitive load values are shown in Table 1.

Note: 1. 24V input series, 24V output series is subject to CY (CY : 1nF/3KV).
2. It is not needed to add the component in the peripheral circuit when
parameter with the symbol of "--".
3. Output load requirements
When using, the minimum load of the module output should not be less than 10% of the nominal load. In order to meet the performance
parameters of this datasheet, please connect a 10% dummy load in parallel at the output end, the dummy load is generally a resistor,
Please note that the resistor needs to be used in derating.
