How to control voltage ac without transformer 0 220v

 

Can you please be a little more specific about this issue so we can help you better?

 

hello
How to control voltage from 0 to 220v without transformer scr

 

O that is simple. Please use one of our thyristor modules for that.
We have them with:
- 1, 2 and 3 phase units
- current from 10-2000 Amperes and above
- voltage up to 690 Volts
- with or without built- in or external super-fast fuses
- heater-break alarm (for detection of broken or short-circuit on heating element)
- current limiter for inductive and MoSi2 loads
- industry 4.0 ready multizone systems with ProfiNET, ProfiBUS, Ethernet/IP, MODBUS RTU and MODBUS TCP interfaces.

For these kind of loads:
- resistive loads (resistance not dependent on temperature)
- inductive loads (i.e. primary side of transformer)
- infrared (IR) long- medium and short wave lamps
- molybdenum (MoSi2) elements (i.e. Kanthal super)
- silicon carbide (SiC) elements
- UV lamps

hello
thyristor will control voltage

 

yes, a thyristor with phase angle control will cut the sinus into a smaller part

 

hello
what is phase angle different between time

 

Hello,
