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 15A÷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.

CD3000S – 2x10A 240V

• CD3000S 2×10 has been designed to drive two loads with 10A current and 240V max line voltage.
• The units provides two isulated independent SSR input circuit
• Zero crossing firing.
• Very compact unit with high-density mounting side by side to reduce cabinet dimension and price.
• High efficient heatsink with chimney effect.
• Easy accessible control circuit board on front unit.
