UPS dual input connection

Increasing resistance of uninterruptible power supplies (UPS), often involves the installation of a UPS configuration known as parallel when the results of two or more modules (in working in parallel) is connected to the supply of charged through a common action bar. A group of UPS modules in parallel is known as an uninterruptible power supply. The two basic configurations are known as parallel redundancy-parallel and parallel capacity. Parallel redundant UPS systems to increase the resistance.

Resistance of parallel redundant uninterruptible power supplies can be further improved by the double entry of supplies to the UPS system is supplied separately from rectifier and static switch supplies. Relying on most of the facilities of food and power supplies UPS bypass static, but creates a single point of failure in design. Should an upstream circuit breaker trip due to a failure, the rectifier and bypass no longer have an AC power source. The use of dual input supplies from separate sources (including separate substation) eliminates this problem.

Typically, transformer-based UPS is a double standard of entry to the facility in the processor, but the model is a factory setting as an option and bypass the rectifier, in this case is based on a deadlock .

Transformer-based UPS

The dual input option in a transformer-based UPS may be selected in the installation by simply removing a connector to link the terminal entrance. The UPS can be powered from two sources of action because this type of bypass module and the rectifier are independent of each other. A typical transformer-based uninterruptible power supply has a rectifier with an input three-phase (delta) and derivation of supply that can have either a single or three phase input neutral more. Some of this type of UPS can also function without a neutral connection.

Transformer UPS

In a transformer and rectifier of the UPS deliveries require a bypass neutral connection, in the module. This type of UPS can be installed with a double, but with supplies from the same source, which is obviously not as strong as if the supplies were coming from separate sources. However, allowing a derivation of energy supply to the load in the event that the UPS has to be temporarily out of service for maintenance, service or repair. The resistance of the uninterruptible power supplies is that each project is the protection to maximize power and dual-input supplies are just one technique that can be used to ensure that the loads can keep despite problems system, such as fault conditions, overloading of closures or power problems of any kind.
