General Details

CD3000S 2PH

From 10A to 90A

General description

CD3000S 2PH two leg switching three wire load star or delta resistive loads or infrared lamps up to 90A.

  • Fully isolated from power.
  • Zero crossing firing available with logic input signal (SSR)
  • Constant current drain with SSR input
  • Analog input 4÷20mA or 0÷10V with burst firing 4, 8 or 16 cycle at 50% power demand, is available as an option from 35A to 90A.
  • Heater break alarm (HB) to diagnostic partial or total load failure and short circuit on thyristor, is available as an option from 35A to 90A
  • Side by side mounting.
  • Special design for heatsink with high dissipation
  • Comply with EMC specification CE and cUL

Downloag Catalog

Heater Break Alarm (HB)

  • Microprocessor based circuit
  • Self learning of current set, via external command or push button on front unit.
  • Load break diagnostic with alarm latch.
  • Thyristor short circuit diagnostic.
  • Alarm reset function and possibility to auto reset the alarm if the normal working condition is restored.
  • Alarm output with free voltage contact.
  • Available from 35A÷90A incl.
  • Full insulation between SSR output coming from controller/multi loop and power supply, no common zero in our unit.
  • Easy and fast substitution/calibrate of the unit (also not expert people can do it easy).

Burst Firing (BF)

  • This firing performed in digital mode in our unit gives a lot advantage because switch thyristor faster than normal ZC and at the same time without EMC interferences.
  • Analog input is necessary for BF and can be decided how many complete cycles we want at 50% of power demand.
  • On CD3000S this value can be 4, 8, 16.
  • To have a better resolution use REVEX series, where the BF value can be implemented from 1 to
    255 complete cycles doing the firing less or more fast.
