- Industrial Power Supplying UPS System
Industrial UPS systems are typically applied in equipment installed in environments with adverse conditions such as poor ventilation, high humidity, and dust. Considering reliability and cost in the most challenging operating conditions for electrical equipment, UPS 1+1 solutions or modular UPS systems are perfect for industrial sites. Modular UPS is recommended because it adopts modular UPS N+X technology which features higher availability and lower cost than standalone UPS 1+1 solutions.
Availability comparison between standalone UPS 1+1 solutions and modular UPS N+1 solutions
| Availability (A(t)) | |||
| 100% Loading | 75% Loading | 50% Loading | |
| Standalone UPS (MTBF=100,000 hours, MTTR=8 hours) | 0.9999 | 0.9999 | 0.9999 |
| Power Module (MTBF=100,000 hours, MTTR=0.5 hours) | 0.99999 | 0.99999 | 0.99999 |
| Standalone UPS 1+1 Solution | 0.99999999 (1+1 Redundancy) | 0.99999999 (1+1 Redundancy) | 0.99999999 (1+1 Redundancy) |
| Modular UPS 4+1 Redundancy | 0.999999998 (4+1 Redundancy) | ≈1 (3+2 Redundancy) | ≈1 (2+3 Redundancy) |

The modular UPS system adopts a design structure of N+X redundancy. Multiple redundancy means that simultaneous breakdown of one or more modules will not affect the operation of back-end loads, which greatly improves the system reliability.
Modular UPS can also decrease the cost of earlier-stage purchases and later capacity expansion, maintenance and operation, showing high cost performance.
High standard components are adopted, and aging testing is carried out for the whole machine before leaving the factory.
Our power module adopts online hot swapping technology, making capacity expansion, maintenance and upgrading risk free. In the rare case of failure, users can replace it by themselves without manufacturer intervention.
Modular UPS systems are designed with IP30 protection degree and the power module is equipped with a dust proof function. Users can remove dust online through simple and convenient operations.
Therefore, a modular UPS system is the best choice for your industrial power supply.
