  • Product description

    Electromagnetic ballast for sodium and metal halide lamps | 70 W | Vossloh-Schwabe VNaHJ 70PZTG.566 | 535657

    Vossloh-Schwabe VNaHJ 70PZTG.566 (article no. 535657) is an electromagnetic ballast for 70 W high-pressure sodium (Na) and metal halide (HJ) lamps. It limits the lamp current and, together with an ignitor, ensures lamp ignition and stable operation. This is a used product intended for repairing existing luminaires.

    Key idea:
    70 W sodium and metal halide lamps are often used in street, yard, warehouse and facade luminaires. When the ballast fails, a Vossloh-Schwabe NaHJ ballast of the same power lets you restore the luminaire without changing its design.

    How it works

    The ballast is connected in series with the lamp. When power is applied, the ignitor creates a high-voltage pulse, and the ballast limits the current once the lamp ignites.

    After the lamp warms up, the ballast maintains the rated lamp current. A compensation capacitor is used in the circuit to improve the power factor; its capacitance is stated on the ballast label.

    The exact wiring diagram, ignitor type and capacitor capacitance are given on the ballast label, so check it before installation.

    Why choose Vossloh-Schwabe VNaHJ 70PZTG.566?
    It is an original Vossloh-Schwabe replacement of the same power: it is wired according to the same diagram as the old ballast, so the repair is simple and the luminaire does not need to be replaced.

    Main functions

    • Current limiting – protects the lamp from overload after ignition
    • Suitable for two lamp types – 70 W sodium and metal halide lamps
    • Simple design – durable, suitable for harsher operating conditions
    • Terminal cover – protects the connections from accidental contact
    • Original Vossloh-Schwabe product – replaced with the same model without modifying the luminaire

    Where is it used?

    • Street and yard luminaires with a 70 W sodium lamp
    • Warehouse and workshop luminaires
    • Facade floodlights with a 70 W MH lamp
    • Car parks
    • Industrial site lighting
    • Park and path luminaires

    Use by need

    For a municipal or street lighting contractor.
    Restores a 70 W sodium luminaire without replacing the pole luminaire.
    For a company technical team.
    A spare ballast for warehouse or site luminaires.
    For an electrician.
    A familiar electromagnetic circuit – wired like the old ballast.

    Practical use

    If a yard luminaire with a 70 W sodium lamp lights up and goes out after a few minutes, and a new lamp and ignitor do not help, the ballast may be faulty. Replace it with the VNaHJ 70PZTG.566, check the capacitor and connect according to the label diagram.

    Pros

    • Original Vossloh-Schwabe ballast
    • Suitable for 70 W sodium and metal halide lamps
    • Durable electromagnetic design
    • Terminal cover
    • Lower price than a new ballast

    Cons / limitations

    • Used product – check the condition and warranty terms on the product page
    • Requires an ignitor and a compensation capacitor
    • Larger and heavier than an electronic ballast
    • Only for 70 W lamps

    Safety and installation notes

    • Disconnect the power before work and discharge the compensation capacitor
    • Check the wiring diagram, ignitor type and capacitor capacitance on the ballast label
    • Do not connect an LED lamp to the ballast – the ignitor pulse will damage it
    • Ensure ballast cooling, do not cover it with insulation
    • Installation must be carried out by a qualified electrician

    Suitable when you need to:
    • Replace a failed ballast of a 70 W sodium or MH lamp
    • Repair a street, yard or warehouse luminaire
    • Keep the existing electromagnetic system
    Check before use:
    • Lamp type and power (70 W)
    • Mains voltage and wiring diagram on the label
    • Condition of the ignitor and capacitor
    • Whether the ballast fits the luminaire: 175 × 70 × 64 mm
    Important reminder: the ballast does not replace the ignitor and capacitor – if they are faulty, they must be replaced separately.

    FAQ

    Is it suitable for a 70 W sodium lamp?
    Yes, the ballast is intended for 70 W high-pressure sodium and metal halide lamps.
    Is an ignitor needed?
    Yes, the ignitor is selected according to the ballast label.
    Is a capacitor needed?
    Yes, to improve the power factor – its capacitance is stated on the label.
    Is it suitable for a 100 W lamp?
    No, the ballast is intended only for 70 W lamps.
