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.
