Practical Control Solutions manufacture a range of SCR firing cards suitable for use in rectifiers and AC power converters used for industrial heating.
The SCR firing cards are suitable for retrofitting to existing installations where old controls need replacement, or for new installations. The SCR firing cards can operate in either burst control or phase angle control mode and can also be fitted with electronic current limit and trip.
The SCR firing cards can be fitted with a power limit function, a feature often used with silicon carbide heaters. The SCR firing cards can be operated in current source mode, a useful feature for plating rectifiers.
In addition to replacement controls, Practical Control Solutions (PCS) can assist with all facets of SCR and rectifier repair, including heat sink refurbishment, replacement SCRs, fuses and cooling fans.
