Reliability, Availability and Serviceability (RAS)

TSINE UPS Systems are functional and reliable to any interruptions and disturbances in commercial grid power.

It consistently perform according to its specifications. Thanks to its innovative, next-generation architecture, downtimes are measured as 0.000001 for a given interval.

Some of the design criterias behind TSINE UPS products as given below:

Over-engineering, all systems by TSINE is designed to specifications better than minimum requirements of the standards.

Some critical parts, components are duplicated as a redundant system to achieve better reliability, avoiding single point of failure.

The UPS XRP is engineered with recoverable methods, it is faul-tolerant and robust to any fluctuations in grid, critical load and any problem which may occur during its operation.

  • The UPS …, keeps extensive records of events, alerts, failures so that trouble-shooting and disaster recovery takes a little time.
  • Power-on replacement, when the systems are still operational, on maintenance bypass mode, the faulty/ broken components or peripherals can be replaced hot swap.
  • While switching from commercial power to backup or auxiliary power, the UPS … can transfer the load to the source with 0 transfer method in 0 miliseconds. The critical load is supplied continuously

The UPS … offers an enhanced serviceability in which a component, parts or system can be maintained and repaired easily. MTTR value is around 15 minutes thanks to early detection of potential problems/ pointing out the exact part(s) which are faulty. The UPS … has also the ability to correct problems automatically before serious trouble occurs; built-in maintenance bypass and automatic & manually activated static bypass allows the user to the maintenance and repair operations with the minimum downtime possible.


Maximized Availability, by the power engineering at its top level, XRP offers very robust

and reliable power protection, this also leads minimized downtime and highest level of availability. Very high level of MTBF [Mean Time Between Failures ] and very low MTTR [ Mean Time to Repair ] ensures the critical load not to fail for its duty.



The UPS XRP is classified as a “ Zero Impact on Source ” so that all effects to connected power sources – grid networks or generators are eliminated.

Current distortion [THDi] is less than 3% & high input power factor close to unity as 0.996 thanks to high frequency IGBT rectifier design and active power factor correction circuity at input.

Thanks to very low harmonics distortion, high input PF & power walk-in feature to ensure progressive rectifier start-up, Genset/ Ups ratio can be selected even 1:1.

Reducing recharge current of the batteries, the current absorbed from the input will be lowered and therefore do not overload the source, especially when the source is a generator. Delayed start-up feature – to restart the rectifier when the mains power supply is restored. Start-up is phased when several UPS are connected in the system.

The UPS XRP also performs the role of a high performance specification filter, protecting its upstream power supply sources (mains or generator) from any harmonics and reactive power generated by the loads powered by the UPS itself.


Three Level Rectifier & Inverter Technology Ultra High Energy Efficiency

The UPS XRP NetXtend FX uses transformerless double conversion technology VFI SS 111, with integrated IGBT three-level design. Thanks to its Vienna Rectifier and Double-IGBT three-level architecture, the UPS offers an online AC~AC efficiency of 97% which minimizes OPEX while guaranteeing a payback of 3-4 years by the savings. The UPS XRP NetXtend FX offering high efficiency values starting at 20% load rates as 95+ %.

As a premium class product, The UPS XRP NetXtend FX offers Unity Power Factor, PF : 1.

Built-in Output Isolation Transformer

The UPS XRP with built-in output isolation transformer offers more reliable, robust power protection for critical applications for the industries, healthcare and data centers in harshest environments. The main features as follows:

  • Isolates and protects the critical output load connected to the ups from DC BUS/ Battery failures.
  • Fault on DC BUS does not affect by-pass availability
  • Higher immunity to harmonics and Energy backfeed generated by the load.
  • High short circuit current resistance
  • The UPS can be supplied from two independent upstream power source.

Easy Scalability

The UPS … offers on-site power upgrade by adding distributed or centralized parallel units to the existing device up to 8 units for ultimate redundancy (N+1) or (N+N).

Proven reliable parallel operation, ease of scalability adds full robustness, redundancy to the power infrastructure and clean, continuous power to the critical load. N+1, N+N installations are much easier than previous versions.

Maximum levels of availability also in the event of an interruption to the parallel bus cable: the system is fault tolerant. It is not affected by connection cable faults and continues powering the load without any break, signaling the anomaly with an alarm.
