Kehua’s MR33 Series 30-1200kVA MODULAR UPS is a 3-phase online double-conversion solution for critical power protection and high-quality power supply of medium and large data centers. UPS with hot-swappable modules, the power capacity starting from 30kVA up to 1200kVA for a single cabinet, and there are 3 kinds of power modules which are MR3330-J, MR3350-J, and MR33100-J to satisfy the on-site requirements of different customers. They are available in 5 sizes, MR33120-300, MR33400-600, MR33600, MR33800, and MR331000-1200 with an efficiency of up to 97% and high reliability.
High Efficiency
● The efficiency of the whole machine is as high as 97%, which greatly saves energy consumption (UPS heat consumption and air conditioning energy consumption) and reduces operating costs.
● The output power factor is 1.0 by default, with the same equipment input cost, greater active output and higher cost performance, which meets the requirements of different application scenarios for high output power factor.
● When the quality of mains supply is high, the ECO mode can be used to supply power to the load, the efficiency of the whole machine is as high as 99%, and the energy saving benefit is remarkable
User-friendly Interface
● Innovative application of data intelligent acquisition technology enables check of all product data in the parallel system on the control panel of any product.
● Large-size color touch screen design and humanized operation
● Double key combination of on and off, double protection of soft and hard
● EPO button with protective cover for emergency shut-off, misoperation prevention design, safety double upgrade
● Man-machine interface is friendly, close to customers' habits, and the software is rich in functions, which is convenient for users to read information and operate.
● Support asset management of vulnerable devices and spare parts
Green Power
● The latest IGBT rectification technology is adopted to realize ultra- low input current harmonics, which eliminates the pollution to the power grid, reduces the cost of power factor compensation and harmonic control, and reduces the cable loss. It protects both the load and the power grid.
● The input power factor is greater than 0.99, which improves the utilization rate of electric energy, reduces the distribution loss at the front end of UPS and reduces the input cost of customers.
