Re:If you need other rated voltage, can be a special order.


1.Resistive load, including the maximum load inductance300μH;
2. According to extrapolated, it is recommended to do experiments for different situations;
3. After life time, diaelectric strength dropped lower than 100MΩ at 1000VDC;
4. The biggest and current.


Re:A1, A2 as the load; 1, 2 for the coil end; Load and coil has no polarity.
