Power is always very unpredictable. Sometimes, it just disappears unpredictably. Whenever such occurs, the most troubled areas are roads that are not fitted with traffic signal UPS. Confusion takes center stage in these places and many lives are likely to be lost. These are, therefore, the areas that need these traffic control machines the most if human life is to be protected.

There are two types of this equipment. The first is made up of a single conversion device while the other one has a double conversion one. The first one is made with the purpose of emitting only sine waves and enough backup for the utility power. This model allows usage of incandescent lamps. It is also possible to connect batteries in parallel. Furthermore, the device makes it unnecessary to use bulky batteries, all in series.

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 double conversion version has many different designs; all of which designed to help handle traffic related problems. With regards to size, there are three different categories of this equipment; 1100 W, 700 W and 1400 W. They all emit seamless waves continuously. There is also an online make of this device that gives absolute power conditioning. It also filters in addition to providing protection against surge and spikes.

The features of this device include; an LCD display for all operations, progressive Ethernet capability and an alarm system which makes it possible for remote monitoring. In addition to these, the device runs for 8 hours, and contains a time meter that is adjustable and has the capability of utilizing any make of batteries. The device is also compatible with generators and has a transfer switch that is automatic.

The basic power management module fitted in these machines is well equipped with a maintenance by-pass switch wrapped around it. It is meant to enable removal and substituting the module without causing disruptions to the equipment. A variety of this device; the Automatic Transfer Switch is capable of being programmed to change the running of the machine from the supporting generator to the utility power when the later returns. It also has a wrap around bypass switch that does functions just like that in the basic version of the equipment.

The function of cabinets in these machines is solely protection. Cabinets keep the inner fragile equipments protected from hostile factors in the surrounding. The materials used for making these cabinets are always strong metallic alloys. The most commonly used metals are stainless steel and aluminum, owing to their rigidity and inability to be corroded. The cabinets have fans which are regulated by thermostats. They also have a three-pointer latching systems, many options for mounting, allowance for optional power generators and doors with hinges that look like pianos.

They have backup batteries, mostly lead-acid ones. These batteries have specially designed epoxies for eliminating leakages. They usually have a life-span of ten years, and manufacturers apply high level technology in giving out high rates and power in a short period.
