Models: PK200FG40 and PK200FG80 — this listing is for PK200FG40 Overview A power SCR (siliconcontrolled rectifier) module designed for industrial and commercial powercontrol applications. The PK200FG series delivers reliable, controllable AC and DC switching in a compact module form factor that integrates easily into assemblies requiring robust power handling and phase control. Key benefits Precise power control: Enables phaseangle and fullcycle switching for accurate regulation of voltage and current to resistive and inductive loads. Simplifies system design: Packaged SCRs reduce discrete wiring and simplify mounting and thermal management compared with individual discrete devices. Robust and reliable operation: Designed for continuous power switching to support industrial loads and reduce equipment downtime. Flexible integration: Compatible with standard gatedrive and trigger circuits used in motor drives, heating, and powerconversion systems. What this module solves Replaces complex assemblies of discrete components with a single, mountable module that reduces assembly time and connection points. Provides a durable switching element for power loads where precise control and repeatable operation are required. Helps manage heat and mechanical mounting through a module format that is intended for heatsink attachment and secure electrical connections. Key attributes Functionality: power SCR module for controlled rectification, phase control, and on/off switching of AC and DC loads. Compatibility: Works with common gatedrive and trigger circuits. Suitable for integration into industrial motor controls, heater controllers, power supplies, welding equipment, and similar systems. Mounting and thermal: Module format is intended for secure mounting to a heat sink or chassis to enable effective thermal dissipation (follow systemspecific thermal management practices). Electrical interface: Standard module terminals for power and gate connections to simplify wiring and maintenance. Performance: Engineered for continuous power switching and reliable operation in demanding environments; suitable for resistive and inductive loads when used with appropriate snubbers and protection circuits. Typical applications / use cases Industrial motor control: Phaseangle or fullcycle control for AC motor starters and variablespeed drives where a rugged, repeatable switching element is required. Heating and temperature control: Power regulation for industrial heaters, furnaces, and process control systems that need stable, longterm duty operation. Power conversion and welding: current switching in rectifier assemblies, DC power supplies, battery chargers, and welding inverters where compact, power modules simplify design and maintenance. Installation and integration notes Mount to a suitable heat sink or chassis using recommended torque and insulating/thermal hardware as required by your system design. Use appropriate gatedrive circuitry and triggering components; include protection elements (snubbers, fuses, overcurrent protection) per application needs. Follow industry safety standards and electrical codes during installation and commissioning. Models and selection PK200FG40 and PK200FG80 are available in the PK200FG series.
