The Olympus DLSR E-410 does not include a AC adapter. This Battery dummy (suitable to replace batteries of the type PS-BLS1) can with minimal additional parts be used to connect the camera directly to a suited AC-adapter. The Battery voltage is 7.2V or below down to about 6.8V. Too high voltage will result in the destruction of the camera.
The use the dummy as an AC adapter is needs metal electrodes (self adhesive copper foil works fine) and a 10kOhm resistor connecting ground and the middle electrode.
Buffer capacitors are also a good idea ( used 0.1 uF and 45 uF in parallel).
Be careful with the polarity - wrong polarity will probably also damage the camera. In the photos the red wire is connected to 7V, the black wire to ground.
I was able to use this adapter to automatically run the camera for several nights without damaging it.
