220V CONVERSION?
220V CONVERSION?
(OP)
I'm currently faced with a problem of converting a 220v supplied mechanism to battery operated. Is this possible first, and secondly where would I start?

RE: 220V CONVERSION?
Case 1:
If the actual mechanism has an in-built rectifier/regulator and all the power is drawn from the output of the recctified supply, I feel it's much better to bypass the AC section, and directly feed with a DC. This is advisable because
i) it's pretty costly to go for an inverter
ii) it's unnecessary to have a DC-AC inverter and then an AC-DC converter, if you can straightaway supply DC.
Depending on the DC voltages and power consumption, you may need to go for DC regulators. Still, this'll be cheaper than an inverter.
Case 2:
If the mechanism uses AC: Then, there's no other alternative- you've to go for an inverter, as suggested by dbaird above.
In both cases, a study of the power consumption of the mechanism is of utmost importance.
