Meidensha UPS Series Uninterruptible Power Supply
Manufacturer: Meidensha Corporation
Model: UPS Series
Features
Overall efficiency of the transformerless 400 V series
Overall efficiency of the transformer 200 V series
Output voltage transient variation characteristic (transformer 200 V series). IEC62040, AC output voltage transient variation characteristics.
We have been producing and conducting sales of uninterruptible power supply (UPS) from 1961 to today, and it has been used by customers in various industries.
We have two types of lineups, the 400V input/output series and the 200V input/output series, for the three-phase output UPS, and both of them have implemented high efficiency, space saving, and longer operational life of the main periodical replacement parts.
- Reduction of electricity cost through high efficiency (97% or more with the 400 V series, 92% or more with the 200 V series)
- Reduction of operating cost with longer operational life of the periodical replacement parts
- Effective utilization of customer’s space in a space saving
- Output voltage transient variation characteristics (IEC62040-class 1 compliance) of the industry’s highest class
- 24-hour 365-day security support system with a remote monitoring function (optional)
Applications
Various customers—including financial services, broadcasters, government offices (prefectural buildings and city halls), public facilities, data centers, and general commercial buildings—use our UPS in their critical load facilities.
Meidensha Corporation provides the optimal UPS system meeting customer’s needs.
Single machine system
A system configured with one UPS
During UPS inspection, the maintenance bypass circuit continues the power supply to the load.
Parallel / individual switching system
Connecting multiple UPS units with built-in bypass switching circuits in parallel configures a parallel system that requires no common switching circuit.
Even if several UPS units fail, the system removes only the faulty machines from the parallel connection while the remaining units continue to power the load.
During inspection, the UPS can be continue powered by parallel release / parallel input of UPS one by one.
Common spare system
This system configures multiple UPS for each targeted load and backs them up with buckup UPS
The backup units supply power to the load if the regular machines fail.

High efficiency and High performance
High Efficiency
Transformer 200V Series: Achieves industry-leading efficiency of 92% or more (20–300 kVA), peaking at 92.5% for the 300 kVA model.
Transformerless 400V Series: Reaches an industry-high 97% efficiency by utilizing a 3-level PWM conversion circuit.
High Performance
Delivers stable power by fully meeting JEC2433-2003 Class 1 transient voltage standards, even during 100% sudden load changes.
Space saving
- Board dimensions of the UPS transformer 200 V series
- The new design reduces dimensions by 40% compared to the conventional board. (300 kVA machine)
- Board dimensions of the UPS transformerless 400V series
The new design reduces dimensions by 33% compared to the conventional board.
