What is an uninterrupted power supply (UPS)?
The human desire to have a steady power supply for domestic and industrial purposes gave rise to an uninterrupted Power supply (UPS). Globally, the need and demand for computers, electronics, and other electrical devices are on the rise. These types of equipment required quality, high stability, and uninterrupted power supply.
What are the requirements for the ups to comply with IEC 62040-2?
The UPS shall conform to the electromagnetic emission and immunity levels in IEC 62040-2 for the specified category level. The sound pressure level, measured at a distance of one metre from the UPS in any direction, shall not exceed the specified value, at load conditions ranging from no load to the rated load.
Why should a ups be protected from a short-circuit?
The UPS should be so designed and constructed that it is protected against damage resulting from disconnecting the batteries or, with the battery disconnected, short-circuiting the UPS battery connections. If this protection is provided by electronic means it should automatically reset following removal of the open or short-circuit conditions.
What is the internal control supply of the ups?
The internal control supply of the UPS shall be available provided any of the power sources to the UPS are present. The inverter unit shall control the output of the UPS to maintain synchronism with the bypass voltage during variations in input frequency, within the specified tolerance limits.
