Second, the performance characteristics

TPM Series modular UPS system not only has the characteristics of parallel redundancy, you can completely replace the traditional 1 +1, 2 +1 and systems, and is a "green power" program, with a high input power factor, low harmonic distortion, high efficiency and high stability and reliability advantages, with powerful monitoring software and comprehensive communications interface for precision equipment and bodies, in particular telecommunications, power industry applications.


1. Redundancy

TPM system parallel redundant UPS power supply, three insingle-out, three-threein, single or single out single in more than three standard operation. System from the power distribution unit, system monitoring, static switch and 1 to multiple power modules, power modules can be hot-swappable expansion mode free replacement.

TPM system for all power modules in the array system load average burden, the parallel modules are built-in redundancy intelligent independent individual, without parallel system monitoring system for centralized control. After the failure of any module (including system monitoring), redundant design TPM system will be fully effective, comprehensive protection for normal operation of equipment to achieve the greatest degree of fault tolerance, while the user can select more than one redundant fault tolerance required .


TPM extremely flexible system architecture, power module design concept can easily be removed and installed without affecting the operation and output of the system when the system is running, make the investment plan to achieve "on-demand extensions", allowing users with business development to achieve "dynamic growth ", both to meet the post-equipment demand expansion, but also reduce the initial purchase cost.


TPM system in parallel with superior functionality, UPS is a leading representative of the high-end technology, the MTBF values ??(MTBF) is 1.5 times that of traditional UPS, the average no significant fault value (MTBCF) is three times that of traditional UPS systems, the average repair time value (MTTR) is only five minutes in the system to normal operation.


TPM system battery pack (± 384V) from the system all UPS modules share (including charging and discharging). Use it according to user needs a battery or multiple batteries in parallel to increase the system standby time. TPM system uses a flexible way to access the battery, the battery voltage and reduces the quantity and improving the life of the battery pack.


TPM system uses a three-phase five-wire power module input. TPM system online operation, regardless of three single out, three-three, single-entry three or single into a single work, regardless of whether the output load balancing, enter zero line no mains current, no voltage, thus Safety critical equipment to meet the various requirements of the zero voltage of.

6.Environmental protection

PFC circuit TPM system uses advanced active average current control technology, can achieve input current total harmonic distortion (THDI) only 3%, while the unit input power factor PF = 0.99. Under linear load condition, greatly reducing the power grid pollution, reduce network load and power consumption, overall efficiency up to 95% energy savings.


TPM system built-in sound power analysis and a variety of communication interfaces with intelligent monitoring software, two-way interactive communication through a variety of communication interfaces and administrators, allowing administrators to remotely monitor the system at any time, a number of anomalies pretreated Always make the system stable and reliable operation.

Each module is set inside a dedicated charging rectifiers, high reliability, no high frequency noise, to avoid the impact of high frequency waves on battery life; avoid overheating while charging the battery, extending battery life.

Intelligent battery management:

  • Provide battery self-discharge function. For long-term operation can not discharge the battery system, the discharge operation can be performed manually. Discharge process has multiple levels of protection, the activation of the battery at the same time, protect the load safely.

  • Are using advanced, float conversion technology, according to the charging current of the battery cell capacity to detect and judge, automatic float conversion, saving charging time, activation of the battery, thereby extending battery life.

  • Can be automatically adjusted according to changes in ambient temperature float voltage, the effective capacity to ensure maximum battery to extend battery life.

  • Can be connected in parallel using automatic current charger, sharing imbalance <5%, to meet the user's desire to restore the energy reserves of the battery as soon as possible.


TPM system uses advanced technology hot-swappable UPS module, a single module can be put into any online or exit parallel unit, no power to operate. Achieve a parallel system of online maintenance, while the operation without specialized equipment and techniques can be carried out.
