- Uninterruptible power supplies provide backup power, protecting equipment from damage in the event of grid power failure.
- UPS systems serve two main purposes. They provide backup power as quickly as possible in the event of power loss, and they offer some degree of protection from power quality issues that may damage equipment. UPS systems fulfil these goals to varying degrees depending on their design and features, which ultimately affect their costs.
Types of Uninterruptible Power Supplies
- UPS systems provide a comprehensive, modular solution to protecting sensitive equipment from power supply problems.
- Depending on power quality issues to be addressed, three types of UPS systems are used:
- Double conversion or online UPS
- Standby or off-line UPS
- Line-interactive UPS
Maintenance of UPS
- The maintenance required for UPS systems is generally minimal.
- Battery health is the greatest concern in ensuring the overall effectiveness of a UPS system.
- Confidence in the UPS system’s ability to provide necessary run time depends on good battery maintenance.
- Maintaining UPS batteries entails periodic cleaning and testing as well as proper replacement at the end of the battery’s life.
Understanding the UPS Alarms?
Types of UPS Alarms
1. Audible Alarm
- The common scenarios that will produce different types of audible alarm from CyberPower UPS.
| Scenarios | Different types of audible alarm |
|
UPS in battery mode |
When the UPS is running on battery power, it will typically emit 2 short beeps every 30 seconds. |
| Low Battery | If the internal battery of the UPS is almost out of charge, it will usually emit rapid beeping sounds twice every second. |
| Overload | Once the UPS has detected an overload condition, it will generally emit a long and continuous beeping sound. |
2. Visual Alarm
- UPS is also equipped with either an LED indicator or LCD to indicate the health of the model.
| Scenarios | Different types of visible alarm |
| LED Indicator | Some UPS also come with LED indicator with three colored lights: green for normal, yellow for warning and red for fault notices, showing clear product status. |
| LCD Display |
On the other hand, most UPS are built-in with an LCD display to indicate detailed information such as battery mode, low battery, overloading and UPS fault to alert users of potential problems that might affect critical equipment and cause downtime. |
| Colour LCD Display | Featuring color LCD function, the newest CyberPower UPS models not only can display real-time information, but also help users to easily identify UPS status: green for normal, yellow for warning, and red for fault notices. |
3. Visual & Remote Alarm
- The remote management solution helps users to monitor the product status anytime, anywhere.
|
Scenarios |
Different types of visual and remote alarm |
| Remote Management Card | With the SNMP card installed, it allows users to perform remote management of UPS. Once an event happens, users can be notified through email, SNMP traps, Syslog or SMS. |
| Power Management Software | The software helps users to manage the UPS locally or remotely. Besides providing an overview of system operation, the software can also send warning notifications automatically when a system event occurs, ensuring any faults to be dealt with timely. |
