The new combined fencers AN15 and AN25 are 12 Volt fencers. The connection for the 12 Volt battery is located on the inside of the fencer, so that a 12 Volt battery can be connected. On the reverse of the fencer there is an additional connection plug for a mains adapter. (Available as spare part with part no. 47PSU0008UK). With this mains adapter the fencer can be operated with 230 Volts. With the connection of mains adapter 47PSU0008UK and super vlies battery 15842 the combi fencers can also operated in stand-by mode. This means that as soon as 230 Volts mains stops, the fencer automatically is operated with 12 Volts.
