General Details

CD3000S 1PH

From 10A to 90A

CD3000S 1PH is the single phase version of our low cost family of solid state relays designed to replace the now obsolete contactors.

Single-phase thyristor units up to 90A.
Applicable for resistive loads and infrared lamp.
Zero crossing firing available with logic input signal (SSR)
Voltage power supply: 24V min, 480V Max, 600V on request
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 15A to 90A
Heater break alarm (HB) to diagnostic partial or total load failure and short circuit on thyristor, is available as an option from 15A to 90A
Mounting: Din rail mounting up to 90A included, bulkhead over 110A, IP20 protection
Special design for heatsink with high dissipation
IP20 protection
Approvals: EMC; cULus available as an option on basic units

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).

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 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.
