BERTAN 2554-2 0-30KV 400uA DC High Voltage Power Supply HAS RIPPLE ON LINE, READ

Power supply powers on, supplies a high voltage, but there is a ripple on the high DC line. At 3kV, the ripple has a magnitude of ~0.5kV.

The ripple is in the shape of a triangle wave, and with a capacitor/inductor pair could be attenuated significantly.

This ripple in the output is why the unit is being sold "for parts".

Thanks for looking!
