The TN22 has been specifically developed for use in electronic starter circuits. Use in conjunction with a sensitive SCR and a resistor, it provides high energy striking characteristics with low triggering power. Thanks to its electronic concept, this TN22 based starter offers high reliability levels and extended life time of the fluorescent tubelamps.
