ALPHA series thyristor modules are designed to switch capacitive loads up to 80 kVAr in power factor correction (PFC) applications. The modules can switch capacitive loads within 10ms of receiving a triggering signal. The microprocessor-based architecture and its algorithm switches at the voltage zero crossing, thereby avoiding capacitor abrasion

MAIN FEATURES of ALPHA SERIES THYRISTOR MODULES

• Up to 480V, star-or delta-connected symmetrical or asymmetrical loads
• Easy triggering from PFC relays or PLCs •  Longer life expectancy
• Fast switching performance – typically below 10ms 
• Guaranteed transient free capacitor switching 
• Monitors voltage, status and temperature 
• Records detected faults, provides a dry contact output and displays faults on front panel 
• Can operate with or without a detuned filter reactor. 
•  Provides external thermostat connection which can be used to protect detuned filter reactors 
• Maintenance free 
•  Quiet operation
