( Brand: Mitsubishi ), ( Manufacturer Part Number: MR-J2S-20A-EG )
The Mitsubishi MR-J2S-20A-EG is a 20 kVA/120 kVA Online Double Conversion Uninterruptible Power Supply (UPS) system, designed to provide reliable and high-quality power protection for critical loads. This UPS system is equipped with advanced features to ensure uninterrupted power supply, even during power outages or voltage fluctuations.
This UPS system comes with the Fedex Parallel Redundancy module, which provides an additional layer of power protection by allowing the connection of up to four MR-J2S UPS systems in parallel. This configuration provides a total capacity of up to 480 kVA, making it ideal for large data centers, hospitals, or other applications that require a high level of power redundancy.
The MR-J2S-20A-EG is an online UPS system, meaning that it converts the incoming AC power to DC power and then back to AC power continuously, providing clean and stable power to the connected equipment. The double conversion design ensures that the output power is free from harmonic distortion, voltage spikes, and other power quality issues.
Key Features:* Online Double Conversion Design: Provides clean and stable power to the connected equipment.
* Parallel Redundancy: Allows the connection of up to four MR-J2S UPS systems in parallel for increased power capacity and redundancy.
* High Efficiency: Achieves an efficiency level of up to 96%, reducing energy losses and lowering operating costs.
* Automatic Voltage Regulation (AVR): Corrects voltage fluctuations and maintains a constant voltage level at the output.
* Automatic Frequency Correction (AFC): Corrects frequency fluctuations and maintains a constant frequency level at the output.
* Low Harmonic Distortion: Reduces the harmonic distortion level at the output to meet the IEC 61000-3-2 Class 2 requirements.
* Battery Backup: Provides backup power during power outages, ensuring that the connected equipment remains operational.
* Input and Output Filters: Filters the input and output power to eliminate electromagnetic interference (EMI) and radio frequency interference (RFI).
* Remote Monitoring and Control: Allows for remote monitoring and control of the UPS system through the Snap-in Programming Software or the Built-in LCD Display.
* Communication Interfaces: Provides various communication interfaces, including SNMP, Modbus, and RS-232, for seamless integration with other systems.
The Mitsubishi MR-J2S-20A-EG 20 kVA/120 kVA UPS System with Fedex Parallel Redundancy is an ideal solution for applications that require a high level of power protection and redundancy.

The Mitsubishi MR-J2S-20A-EG UPS (Fedex Model) is a 2000VA/120V/300W uninterruptible power supply (UPS) designed to protect sensitive equipment from power outages and surges. In this analysis, we will discuss the key features, advantages, and disadvantages of this UPS model.
Key Features:1. 2000VA/120V/300W output capacity
2. Line-interactive topology
3. Automatic Voltage Regulation (AVR)
4. Eight outlets: 4 battery backup and 4 surge-protected
5. USB and RS-294 interfaces for monitoring and communication
Advantages:1. Automatic Voltage Regulation (AVR) ensures that the output voltage remains constant and protects the connected equipment from voltage fluctuations.
2. The UPS is relatively compact and lightweight, making it suitable for home and small office use.
3. The eight outlets provide flexibility in connecting various devices, including computers, monitors, printers, and other peripherals.
4. The USB interface allows users to connect a USB drive for data logging and configuration backup.
5. The RS-294 interface enables communication with building automation systems and energy management software.
Disadvantages:1. The line-interactive topology may not provide the same level of protection against power surges as an online or offline UPS.
2. The battery backup time may not be sufficient for longer power outages, as it is designed primarily for short-term backup.
3. The UPS does not come with a battery included in the package. Users must purchase the battery separately.
Conclusion:The Mitsubishi MR-J2S-20A-EG UPS (Fedex Model) offers a good combination of features, advantages, and affordability for small home or office use. Its automatic voltage regulation, compact design, and flexible outlet configuration make it a suitable choice for protecting sensitive equipment from power fluctuations and short-term power outages. However, users should note that it may not provide the same level of surge protection as a more advanced UPS and may not be suitable for extended power outages without an additional battery.
Recommendation:If you require surge protection and short-term backup power for a small home or office setup, the Mitsubishi MR-J2S-20A-EG UPS (Fedex Model) is an excellent choice. However, consider purchasing a battery pack to extend the backup time during power outages. If you require more advanced power protection, consider a more robust online UPS system.
