Delta's NT series industrial-grade UPS has always been an ideal choice for applications that require high power safety due to their high reliability and high-density planning. IGBT high-frequency switching sinusoidal pulse width modulation technology planning, which makes UPS have the advantages of good power supply quality, high efficiency, low heat loss, low noise, small size and long life.
In the face of the general trend of the IT environment, national commercial banks have begun to build regional operation assurance bases, including: regional branch and community branch security system, branch operation management system, as well as cash vault, depository, precious metal vault, safe deposit box and other systems to ensure the reliable operation of banking business.
The Delta NT series satisfies these points very well. Through the digital planning of the microprocessor, simplifying the messy imitation lines and reducing the number of parts, the NT series UPS system is more secure and reliable, which greatly ensures the data security of the bank information system. Thanks to the modular planning, the NT Series UPS reduces mean time to repair (MTTR) and makes protection easier
Together, in order to further improve the reliability of the power supply system, Delta has planned a "1+1" parallel shared battery pack optimization plan for the UPS power supply system of the operation and security base, using the direct parallel technology and shared battery pack function of Delta's NT series industrial-grade UPS. It can be directly paralleled, which eliminates the problems brought by the addition of parallel cards or parallel cabinets to the entire power supply system, and greatly improves the reliability of the power supply system. The "1+1" parallel redundant power supply system can still ensure that the power supply system continues to provide uninterruptible power supply for the load in normal operation, so that the reliability of the system is improved. Delta's NT series UPS also has an online parallel function, which does not require stopping or jumping bypass to the running UPS during paralleling, and can fully meet the user's uninterrupted safety assurance even when the system is expanded and protected.

The reason why the circuit breakers of multiple stages trip together is Delta
Short-circuit maintenance (overload maintenance) is an important function of circuit breakers, and the reason why this function is achieved is that the circuit breaker senses the temperature in the circuit through a thermal iron plate. Once the temperature in the circuit is too high, it is transmitted to the mechanical mechanism in the circuit breaker for trip maintenance.

Analysis of misunderstandings in the application of Delta inverters
The capacity selection of the inverter is based on the rated power of the motor
Myth: The capacity selection of the inverter is based on the rated power of the motor
Compared with the motor, the price of the frequency converter is the most expensive, so under the premise of ensuring safe and reliable operation, the frequency conversion can be reasonably reduced.

The key point to pay attention to when choosing a UPS power supply - Delta
(1) About the synchronous switching function. Now, in addition to the off-line UPS power supply with an additional output power of less than 500VA, the off-line UPS power supply with square wave output is still selected for conversion control without mains synchronization function, and all UPS power supplies with an output power of 1KVA and above are performing the conversion operation of mains power supply to inverter power supply.
