No. It means it can ring a set of phones that add up to 5 REN. This number does not equate to watts.
The unit has to power the electronics, send out talk battery, add superimposed DC on the ringing voltage. Generate the ringing circuit, etc. >From + and - 12 volts, we get -48v talk battery and ringing voltage(I have not measured it, but I would be surprised if it was less than +- 80v and then I would use a scope and not a volt meter to accurately measure it) all for free with no loss(wattage) in the conversion? I would not even consider trying to equate one to the other.
