Low Voltage General Purpose Transformers (Buck Boost Transformers)
  • Features

    • Designed to supply 12/24, 16/32, or 24/48 circuits at the name plated kVA.
    • Dual primary and Dual secondary isolation transformers, allowing for 12 field connected auto-transformer connections for 5%, 6.6%, 10%, 13.3% 20% or 26.6% change in voltage for single phase or 3-phase configurations.
    • Unique enclosures for each kVA size - giving the most compact units in the market, and not supplying greater than 3kVA when the cable sizes start to exceed the wiring compartment for isolation transformers sizing.
