The transformers within our range portable site transformer range are ideal for stepping down voltages to 110V when using power tools on the construction or building site. The units are either 240V single-phase (1ph), 415V two-wire (2ph), or 415V three-phase (3ph) and have continuous power ratings ranging from 3kVA to 30kVA (4kVA to 35kVA 20 minute tool rated). The smaller units from 3kVA to 5kVA continuous are suitable for heating and lighting applications and feature a number of cable gland and/or socket combinations. The larger units from 10kVA to 30kVA continuous feature between 6 and 12 sockets.
