| http://www.w3.org/ns/prov#value | - The direct current voltage preferably ranges from + or -50 to 2,000 V, particularly 100 to 1,500 V. The alternating current voltage superimposed thereon ranges 400 to 1,800 V, preferably 800 to 1,600 V, more preferably 1,200 to 1,600 V in terms of the voltage between peaks.
