UL standards assist in power failure protection, voltage regulation, power factor correction, and harmonic control

Meets all the requirements of power supply protection for sensitive loads. UL standard UPS and voltage regulation products and technologies cover applications from small computer rooms to large data centers and protect a wide range of industrial equipment. Product power coverage ranges from several kilowatts to several megawatts, voltage from low to medium voltage. All your power needs can be met in these applications.

The main function of UPS is to provide clean, continuous power to downstream loads. According to IEC 62040-3, if the UPS cannot provide clean energy or the correct voltage, the UPS will transfer the load to a static bypass switch. UPS as a kind of power supply in the power grid, the characteristics and operation mode of UPS should be considered in the system and protection design. UPS inverters limit the transmission capacity of the downstream short-circuit current to 2-3 times its rated current value, while static bypass switches are typically designed to carry at least 10 times the rated UPS current for 20-100 milliseconds. During a downstream load failure, the load breaker needs to be cleared as soon as possible to restore voltage on the output bus and stay within the ITIC requirements of the other connected IT loads.

In DPA, each UPS module contains all the hardware and software needed for the full operation of the UPS system. There are no common components shared between modules, and each module is a fully functional UPS, so a DPA parallel system provides extremely high system reliability and maximizes uptime. UPS modules can be arranged in parallel to provide redundancy or increase the total system capacity.

True "plug-and-plug" modularity enables the safe removal and insertion of UPS modules without the risk of critical load and without the need to transfer or disconnect them from the original power supply. As a result, one can replace or add modules without having to implement any system downtime. It is also easy to upgrade power capacity as critical load power demands grow. In addition, if a failure occurs, one can easily remove the module for repair or replacement without affecting the availability of the entire system. Only a truly redundant architecture like DPA can enable online module insertion and removal while the system is up and running.
