SCR Direct Control Panel
Scarlet Alloys Wire SCR (Silicon Controlled Rectifier) Temperature Control Panels come with the On-Off panels with the following options:
CTRL Transformer
Contactors and Fuses for multiple load variations
Advantages:
Also known as Phase Angle Controllers or solid state switching device – work using the modulation of the load voltage until the targeted temperature is reached. Its smoother temperature control (virtually no noise) makes it a preferred choice over mechanical contractors which involves full load on/off during a cycle and improves your temperature response time. Maintenance costs can be reduced as well as there are virtually no arcing or sparking. SCRs can reduce the possibility of thermal shocks in electric heaters. SCRs have infinite resolution which gives it many advantages. They are less likely to wear out and are less expensive. Fuses should be calculated at 25 percent of the full electrical load.
