Overview
With the fast development of telecom and network technology, UPS is widely used in various industries and advanced UPS is greatly required. A new generation of integrated, flexible and reliable UPS is coming to the stage of UPS industry. SCU modular UPS is a true online double conversion modular UPS product. It could take the place of traditional 1+1/2+1 parallel system. It is a green power solution, with high input PF, Low THDI, high efficiency, stability and reliability. It has monitor software and communication interface for local and remote management. SCU has a full range of modular UPS product and many success customers in various industries.
In standard structure, SCU modular UPS takes small footprint. It is designed with UPS module as basic component and other excellent configurations, to provide perfect power solution to customers.
Features
High reliability
Reliability of UPS= MTBF+Redundancy. Hence
redundancy design is the best way to increase reliability of
UPS in current UPS industry.
SCU modular UPS marks a great breakthrough in UPS
technology
Potential Danger of Standalone
UPSs Parallel
- Standalone UPSs parallel cause circulation or current
circulation, even system downtime. - If STS of any paralleled UPS fails, the whole system
will fail. - If the load power is not well distributed,. the system
may fail. - Great danger in online expansion, update and
maintenance. - In conclusion, the more standalone UPSs are parallel,
the less reliable the system is.
SCU Modular UPS Design Idea
- Eliminate circulation affection caused by UPS module parallel.
- Centralized bypass and STS. Control circuit and switch device are separated from main power circuit.
- Multi-Ievel decentralized control. All of the UPS module,
monitor module and STS module are online hot- swappable,
which help to make online expansion, updated and maintenance very safe. - Current sharing control technology is used in input, charger,and output of UPS module.
- In conclusion, SCU modular UPS decreases future value and provide complete protection to load and UPS.
- MTBF.hours
- MTBF.mins
High Availability
Availability= MTBF/ (MTBF+MTTR)
MTBF= Mean Time between Failures
MTTR= Mean Time to Repair
- If a UPS module fails, the UPS system will still work normally.
- No need of trouble shooting. Remove the failing module to solve the problem. So the user can conduct maintenance by themselves.
- MTTR is 5 minutes. Standalone UPS needs 8 hours
- Simple spare parts decrease maintenance costs.
- If the monitor module fails, UPS keeps normal operation
- Support by online maintenance at any time. Eliminate potential failure
- High reliability and stability ensure the best protection to the load.
- High availability provides full time protection to both load and UPS
High Investment Efficiency
Investment efficiency includes:
Reduce initial investment, expansion, maintenance costs
SCU UPS is a flexible modular structure. UPS module can
be added or removed online, without forced shutdowns. It is
pay as you grow.
Decrease operation cost
Final targets of power equipment: High efficiency, No
pollution, Energy saving
Advantage of SCU modular UPS:
≥95% overall efficiency;
THDI≤3%;
Input PF≥0.99

Power Solution
Solution 1 : INDUSTRIAL CASE STUDY
For industrial customers, we recommend modular UPS N+X solution.
Comparing with standalone UPS 1+1 solution, modular UPS N+X solution
features with high reliability and high cost-efficiency.
Solution 2 : TELECOM CASE STUDY
In the cases where UPS is used to power IT equipment, 2N power
mode is the safest with the best security solution.
2N power solution, provide two independent power sources to protect
the electrical systems against unexpected power failure. The
loads are powered by both power sources, or the two
sources feed power independently to their own loads.
Solution 3 : DATACENTER CASE STUDY
There are many critical computers and other load equipment in modern datacenter, which has very strict requirement on power supply system. Easy maintenance, easy expansion, fault tolerance, cost-effective, and energy saving are all datacenter user’s concern. 2N power solution and △ 2N power solution both apply to the datacenter equipment. Now we introduce the △ 2N power solution in details △ 2N power solution scheme
1) Normal condition, double bus solution for each group of load. Each UPS could bear load of 66% of rated power max
2) If one UPS fails, the remaining two UPSs share the three group of load.
