West Control Solutions offers a family of thyristor power controllers built robust and well suited for industrial applications.
About Thyristor
Thyristor devices’ extended lifespan, capacity to endure surges, and capacity to function at high temperatures make them perfect for power control in heating applications.
The compact design and inexpensive wiring expenses are just two of the many features that West Control Solutions’ single, double, and triple phase power controllers have to offer. Additional features include quick access to internal fuses, heater break alert, zero crossing or burst firing mode, and more. There are additional alternatives for certifications like CE and UL.
We have the appropriate thyristor power controller to satisfy your precise needs, regardless of the load’s constant or variable resistance, inductive or transformer coupling, single or three phases. Thyristor units come in a variety of sizes up to 2600A and 690Vac, with a starting point of 3A.
Descriptions of PMA Relay C
Sophisticated load control up to 800A for one, two, or three phases. These devices have better performance, protection, monitoring, communication, and a wider variety of firing modes.
A range of load types can be controlled by the adjustable zero-cross, phase angle, delayed triggering, single cycle, burst firing, and half cycle modes. These include UV lamps, transformers, mid- and long-wave infrared lamps, NiChrome, silicon carbide, tungsten, and molybdenum heating components. For optimal visibility, the range can be connected to an easy-to-use commissioning tool.
