    Operating principle

    The electronic ballast is used in the power circuit of fluorescent lamps. It is designed to control and supply the connected lamps using a 220–240 V AC, 50–60 Hz mains voltage.

    TJB-E418SP can operate with several different lamp configurations. It is important to select the correct lamp type, power and quantity because a different input current is specified for each configuration.

    Compatible configurations: T8 4×18 W, T9/T10/T12 4×20 W, T8 3×18 W and T9/T10/T12 3×20 W.

    Compatibility with lamp types

    The ballast is intended for T8, T9, T10 and T12 fluorescent lamps. 3 or 4 lamps can be connected, but their rated power depends on the lamp type.

    T8 lamps
    3 × 18 W or 4 × 18 W
    T9 / T10 / T12 lamps
    3 × 20 W or 4 × 20 W

    Input current by lamp configuration

    The ballast input current depends on the type, power and number of connected lamps. All specified configurations are intended for 230 V, 50–60 Hz supply.

    Lamp type Configuration Voltage Frequency Input current
    T8 4 × 18 W 230 V 50–60 Hz 0.32 A
    T9 / T10 / T12 4 × 20 W 230 V 50–60 Hz 0.35 A
    T8 3 × 18 W 230 V 50–60 Hz 0.24 A
    T9 / T10 / T12 3 × 20 W 230 V 50–60 Hz 0.27 A

    High power factor – PF 0.98

    TJB-E418SP has a power factor of 0.98. A high PF value is important in electrical installations with larger quantities of lighting equipment where more efficient loading of the electrical network is desired.

    PF 0.98 – one of the most important electrical characteristics of this electronic ballast.

    Harmonic distortion and lamp current crest factor

    Total harmonic distortion THD is less than 20 %, while the lamp current crest factor Lamp CCF is less than 1.7.

    THD
    <20 %
    Lamp CCF
    <1.7

    Operating and maximum case temperature

    The electronic ballast is designed to operate at ambient temperatures from −25 to +50 °C.

    Maximum permitted case control point temperature – tc 70 °C.

    Temperature limits: ta −25...+50 °C, tc max. 70 °C. During installation, it is important to ensure that the ballast temperature limits are not exceeded.

    Integrated protections

    TJB-E418SP includes protection functions intended for ballast operation under abnormal lamp conditions.

    Lamp disconnection protection
    The ballast has protection that operates when a lamp is disconnected.
    Lamp fault protection
    Protection is provided for lamp fault conditions.
