Components Of Traffic Signal UPS

By Marci Glover


Power crisis has become rampant nearly everywhere. A single occurrence maybe very fatal, especially when it hits roads that lack traffic signal UPS. This may cause collision of vehicles due to the confusion that ensues. These back up machines always help avoid such incidents by taking up the responsibility of supplying power to the control lights. This machine is, therefore, worth investing in since it saves many lives in case of emergencies.

These machines come in two designs; those that are single conversions and the more advanced double conversion ones. Single conversion devices were created with the intention of making them produce sine waves and also support the primary power generator. Incandescent lamps, which do not work on other models, work on this model, and parallel connections are also possible. Due to the way it was designed, there is no need of using bulky batteries.

This machine runs for a minimum of 8 hours, has an all-inclusive alarm system, an LCD display that is programmed, an event counter, an adjustable flash timer, a non-compulsory automatic transfer switch to generator, ability to operate using any type of batteries, surge and lighting protection device and Ethernet capability.

The second version; double conversion, is of different models. It was manufactured with the goal of helping attend to the complex and demanding traffic. There are three different sizes of this device; 1400 W, 1100 W and 700 W. All these equipments produce seamless sine waves throughout. An online design provides absolute conditioning of power, filtering and spike and surge protection.

Among the features of this double conversion device are; continuous Ethernet capability, an all-inclusive LCD digital display for every operating functions and an advanced alarm system which allows localized supervision. Other features include; more than 8 hours run time, adjustable flash timer, compatibility with generators, automatic transfer switch and capability to use of the shelf batteries among other features.

The machine has modules for managing power. The elementary module has a by-pass attached on it. This by-pass has the duty of maintaining this device. It also aids disconnection and removal of the module with ease. There is a better design of this equipment which is normally programmed to shift the UPS from the supporting generator back to the primary source of power in case power comes back. It also has a by-pass that performs the same duties it does in the first design.

Devices like the ones discussed above need to be secured owing to their fragility. This is why they are normally kept in cabinets. Cabinets protect them from harsh weather conditions and mechanical destruction. The cabinets are made from heavy metal alloys, particularly aluminum and stainless steel, which provide strong and dependable protection. The cabinets have thermostat controlled fan kits, latching systems with three points, multiple mounting options, provisions for allowance of optional generators and hinged lockable doors.

Lead-acid back up batteries are also fitted into the machine. They are made with special epoxies that eliminate leakages. The life-span of these batteries is normally ten years. Designers of these items always use very advanced techniques in making them give out high rates and power over a short time.
