Ballasts; Transformers; Low Voltage; Low Voltage. An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit.. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube, which would otherwise rise to a destructive level due to the negative differential resistance of the tube's voltage-current characteristic. Our major products include transformer, adaptor, ballast, battery charger, photocell time sensor and cable. The circuit, having high efficiency, operates in a wide temperature range providing ideal ballast curve and reliable ignition for the lamps. A common hot start problem is caused by flooding Strombergs (see recent threads on this). Input voltages on available ballasts in stock range include 120/208/240/277V, 120 VAC, 120-277 VAC, and 120/208/240/277/480V. the current through the lamp is not directly proportional to the voltage across the lamp. If your tests on your Ballast’s both low and high voltage sides appear to function correctly, you can also check wire connections of the tombstones. But, on the other hand, the magnetic ballast provides a very low cost solution for driving a low pressure fluorescent tube.

We find 8 products about low voltage ballast from 5 manufacturers & suppliers. 2.4 Ballast shall contain auto restart circuitry in order to restart lamps without resetting power. This is useful for RVs, boats, solar power installations, green light fishing, and wherever 12VDC or 24VDC is available for lighting. In this event, ballast shall default to maximum light output. The electromechanical ballast has two main drawbacks: a. Ignition of the lamp is not controlled. Public welcome; Visit our new LED showroom … Sort By. The electronic-ballast generates the high voltage for startup using a high-frequency oscillator and so does not need the starter. However, normal ballast-chokes which are wound-inductors along with the starter create the high voltage for the tube to start up based on the principle that interrupting an inductor current suddenly creates a high voltage. Although I think ballasted systems are worth keeping, I dont think this will help with a hot start problem unless your old coil was overloeaded and was failing. Hatch RS12-300 Low Voltage Transformer . The low voltage ballasts are provided for applications where no mains available and for mobile installations. b. Standard metal halide and mercury vapor ballasts have to supply sufficient output voltage for low temperature starting.
