Characteristics
Static striking voltage (tr2 to tr1) 90 to 140V
Max repetition frequency 250 per sec
Min trigger current required at Va=450V 50µA
Min trigger current required at Va=320V 100µA
Typical operation
DC supply voltage 420V
Trigger electrode 2 voltage 60V
Trigger pulse amplitide 160V
Charging resistor 3k ohms
Discharge capacitor for operation at:  
50 cps 2µF
250 cps 0.5µF

A peak anode current of approx 300A results from the discharge of a 2µF capacitor charged at 450V. The discharge time is 5µs and the peak luminous intensity is approx 530 candelas.
