TURNING THE UNIT ON/OFF

ON / OFF / Test Button

Press and release the ON/OFF/Test Button after one beep to turn the UPS ON and supply power to the load. The load is immediately powered while the UPS runs a two-second self test. Press and release the ON/OFF/Test Button after one beep to turn the UPS OFF. The UPS will continue to charge the batteries whenever it is plugged into an AC outlet and there is AC present.

SELF TEST

The self test feature is useful to verify the correct operation of the UPS and the condition of the batteries. With the UPS in the normal On-Line mode, press and hold the ON/OFF/Test Button for approximately 4 seconds (four beeps), then release the button. The UPS will perform a ten-second self test. During the self test, the UPS will switch to battery power and the On-Battery LED will blink and the audible alarm will sound. The length of the test that is automati- cally performed every two weeks is longer than the start-up or user invoked test. This test will run for approximately fifteen-seconds to measure the battery’s capability to provide an acceptable amount of runtime. If the UPS fails a self test, one of the LEDs will remain illuminated indicating the type of problem.

Note: The UPS will automatically perform a self test on start-up and every two weeks.

DIP SWITCH SETTINGS

The DIP Switch setting may be changed by the user to set the desired Inverter (on battery) output voltage and the Low voltage transfer set points. The DIP Switches must be set to the desired Inverter output voltage and the Low voltage transfer set points then, the UPS must be turned OFF and restarted to reconfigure the microprocessor and save the changes. The Inverter (on battery) output voltage setting can be either 120VAC (default) or 127VAC. Changing the In- verter output voltage to 127VAC, will also change the Overvoltage set point from 132VAC (default) to 140VAC. The Low voltage transfer set points can be changed to 85VAC (default) or 80VAC or 75VAC.

The MBK-E Series also includes a wide input voltage range, allowing the UPS to maintain operational capabilities even in fluctuating power environments. This feature is particularly valuable in regions with unreliable power infrastructure. Furthermore, the product is equipped with an advanced battery management system that extends battery life through intelligent charging methods, ensuring that critical systems remain powered during outages.

One of the notable characteristics of the MBK-E Series is its modular design. With an easily expandable capacity, users can customize their UPS systems to meet their specific needs, enabling straightforward upgrades as power demands grow. This flexibility helps organizations efficiently manage their investment in power protection.

In addition to its robust performance features, the MBK-E Series includes comprehensive monitoring and management options. Users can access real-time data regarding power conditions, battery status, and overall system health through an intuitive LCD interface. Remote management capabilities, often facilitated through SNMP or USB interfaces, allow for proactive monitoring and alerts, minimizing the risk of system failures.

The Minuteman UPS MBK-E Series is also designed with energy efficiency in mind, incorporating features such as eco-mode operation to reduce power consumption while maintaining critical functions. By lowering environmental impact and operational costs, this UPS series supports both sustainability and financial efficiency.

Overall, the Minuteman UPS MBK-E Series stands out for its reliability, performance, and flexibility, making it an excellent choice for businesses looking to safeguard their electronic devices and infrastructure against power interruptions. It embodies a blend of cutting-edge technology and user-friendly features, providing peace of mind in today’s power-sensitive landscape.
