PMA RCL Series Thyristor power controller has been
specifically designed to drive single phase transformers
coupled on the secondary with a normal resistance or
special resistance like cold resistance (Kanthal Super) and
Silicon Carbide elements.
This unit has all the drive capability & techniques required,
configurable from the front panel display,close
examination of the transformer application needs to be
made as the typical inrush current, when switched on. This
over-current will have the result of fuse or thyristor failure.
To avoid these peak current two techniques can be used:
Phase angle firing with soft start and current
Burst firing using the Delay Triggering (DT)
This type of firing can be used with all types of loads.
- Cold resistance (Example: Kanthal Super
- Transformer coupled with normal or cold resistance
To avoid magnetic circuit saturation, the thyristor unit
will switch OFF when the load voltage is negative and
switch ON again when positive. The unit also has an
adjustable delay on voltage zero crossing. In this way
it is possible to switch ON when current is zero. This
Firing technique can only be used with normal
resistance, where its resistive value remains constant
with temperature variations
