2. Product Features
the big capacity dry transformer with stainless steel enclosure has
longer service life, better energy saving, lower noise, lower
temperature rise, less ultraharmonics, smaller ripple factor,
strong impulse withstand capability and desirable flame retardant
Temperature controller provides real-time temperature rise
monitoring for energizing transformer, which plays a very important
role in the safe operation of the transformer.
Trip-temperature is outputted after repeated judgment being
confirmed, and its software is interlocked with over-temperature
Trip circuit has resistance-capacitance filtering, interlocked with
over-temperature alarm hardware.
Three-wire system sensing bus and reasonable plug design.
Improved control strategy with temperature compensation function.
Good resistance to electromagnetic interference, certificated by
domestic testing authority.
