Functional Description*:

The electronic power supply SYS 35-70 inverts a DC input supply to a low frequency square wave AC output providing constant power operation of an HID lamp. Fluctuations of the lamp voltage due to lamp manufacturers tolerances, life time and nominal input voltage variation will have no effect to the nominal operating power of the lamp.
The control circuit of the SYS35-70 ballast provides all necessary functions to operate the lamp under specified safe operating conditions as well as failure control by monitoring external or internal abnormal operation. If an abnormal condition occurs the ballast will shut down within 500 ms or less.

Ideal for off grid solar lighting applications.

HID lights are a quality and efficient way to provide light in a variety of industries and environments, providing a powerful, portable searchlight. With its high-intensity discharge, these lamps offer superior lighting and meet the highest industry standards.

Ballasts are part of what make these flashlights so effective. When the right electronic ballast is used, you can create a cost-effective lighting option with energy efficiency and advanced control over how much light is produced.

Electronic ballasts put out multiple frequencies without needing the input voltage altered. This method allows the ballast to function without flickering or buzzing, whereas magnetic ballasts are typically the reason for that buzzing and clicking. If your HID light is running with a magnetic ballast, you could have the noise, but also a less efficient flashlight.

There are two types of starting methods for HID electronic ballasts. The first is a probe start, which can be harder on an HID light. The electrons jump across the arc tube, which is held between two operating electrodes. Once the lamp is started, then the starting probe electrode is detached and removed from being part of the circuit. While this can be an effective starting method, the flashlight can take longer to warm up and reach the full brightness. The re-strike period can also be longer.

Pulse start ballasts, on the other hand, do not use a starting probe, but a high voltage igniter working alongside the ballast. Using this method, the life of your light can be extended and the lumens do not depreciate as quickly.

To determine the right ballast for you, it is important to ask yourself the following questions:

  • What type of light are you powering?
  • Is there a size requirement/constraint for the light?

HID electronic ballasts are made for metal halide, mercury, metal vapor, and xenon short arc lamps. They can also be used with different voltage and wattage levels based on your application.

We feature Auerswald Systems, making our ballasts some of the lightest and most efficient HID electronic ballasts available. AE Light ballasts are ideal in a variety of applications, including portable lighting, medical, automotive, scientific, and industrial.
