THYRISTOR MODULES

MAIN FEATURES of ALPHA SERIES THYRISTOR MODULES

• Up to 690V, star-or delta-connected symmetrical or asymmetrical loads.
• Easy triggering from PFC relays or PLCs
• Longer life expectancy.
• Electronic thyristor commutator (switch) consist inside optically connected input and output wire.
• 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.
