Analytical instruments are designed to operate within a specific voltage range, and laboratory power supplies are usually unreliable and susceptible to spikes, voltage fluctuations, and power outages. These electrical interferences can hinder instrument function, reduce reliability, threaten valuable samples, and cause the loss of vaccines and other biological products in the event of a power outage that affects refrigeration. Incorrect voltage supply can also damage expensive and sophisticated instruments, and may invalidate the warranty, resulting in huge costs for the laboratory. Independent power regulation, uninterruptible power supply (UPS) systems provide local backup and independent circuit voltage correction and protection to keep the instrument running within specifications and warranty scope, and keep laboratory operations online.
Surges caused by accidental short circuits, spikes related to lightning strikes or switching events in the power network expose the instrument to destructive voltages. Similarly, a long-term voltage drop caused by an overload of the power supply network can lead to instrument failure and eventual failure. The circuit protection device ensures that the instrument always gets the correct working voltage to achieve the best function.
In addition to protecting the instrument from electrical interference, the correct operating voltage must also be provided to extend the life of the instrument. Analytical instruments such as thermal cyclers, gas and liquid chromatographs, and mass spectrometers have specific operating voltages specified by the manufacturer, and these voltages are usually inconsistent with the power provided by the laboratory wall socket. Operating the instrument outside the recommended voltage range may cause damage and in many cases will void the warranty. Therefore, they must be connected to a power conditioner to correct the input voltage of the laboratory to within the required specifications through a power distribution unit (PDU) with compatible sockets.
Power outages may occur during inclement weather. Due to the trip of the power station or the overload of the power supply system, the instrument may be affected at any time during operation, resulting in loss of samples. When refrigerators and freezers are affected, the loss of products such as biological samples and vaccines can be devastating to laboratory organizations.
Uninterruptible power supply (UPS) provides reliable backup power for critical instruments until the power is restored. UPS can allow users to complete analysis runs, or keep refrigerators, freezers, and incubators running to maintain sample integrity. The backup UPS system is easy to use, and additional external battery packs can be added as needed to significantly extend the battery backup time.
