Uninterruptible Power Supply (UPS): An electrical device that provides emergency power to connected equipment during power outages or fluctuations, ensuring continuous operation and preventing data loss or hardware damage.
Standby UPS: A basic UPS type that remains in a passive mode until the input power fails. It then switches to battery power to provide backup to the connected devices.
Line-interactive UPS: A UPS system that includes an automatic voltage regulator (AVR) to stabilise input voltage and correct minor fluctuations, enhancing protection against power surges and sags.
Online UPS: Also known as double-conversion UPS, it continuously converts incoming AC power to DC and then back to AC, ensuring a steady and clean output regardless of the input voltage quality.
Hybrid UPS: A combination of line-interactive and online UPS technologies, providing both voltage regulation and protection against power outages.
Output Power Capacity: The maximum power the UPS can deliver to connected devices, measured in Watts (W) or kilovolt-amperes (kVA).
Input Voltage Range: The range of voltages that the UPS can accept as input power, typically specified in Volts (V) or percentage of the nominal voltage.
Output Voltage: The voltage provided by the UPS to the connected devices, ensuring they receive a stable and consistent power supply.
Transfer Time: The time taken by the UPS to switch from mains power to battery power in the event of a power failure. Lower transfer times indicate better protection.
Battery Backup Time: The duration for which the UPS can power connected devices using its internal batteries during a power outage.
Battery Runtime: The estimated time the UPS can provide power at a specific load before the batteries are depleted.
Recharge Time: The time required for the UPS batteries to fully recharge after a discharge event.
Hot-swappable Batteries: Batteries that can be replaced without shutting down the UPS or connected equipment, ensuring continuous operation during battery replacement.
Automatic Voltage Regulation (AVR): A feature in line-interactive and online UPS systems that stabilises input voltage levels, protecting equipment from overvoltage and undervoltage conditions.
Surge Protection: A capability of the UPS to suppress and divert transient voltage spikes, safeguarding connected devices from power surges.
EMI/RFI Filters: Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) filters incorporated in UPS systems to reduce electrical noise and disturbances.
Load Segmentation: The ability to prioritise or group connected devices, allowing users to manage battery backup time for critical equipment during power failures.
SNMP (Simple Network Management Protocol): A communication protocol that enables remote monitoring and management of UPS systems over a network.
Power Factor Correction (PFC): A technology that optimises power usage and improves efficiency by reducing reactive power, resulting in a higher true power factor.
Eco-Mode: An operating mode in some UPS systems that increases efficiency by bypassing certain components during normal power conditions.
Bypass Mode: A UPS operating mode that allows the connected equipment to be powered directly by the mains power, bypassing the inverter and battery.
Load Capacity Display: A visual or digital indication of the current load capacity of the UPS, helping users manage their power requirements.
LCD Display: A user-friendly display panel on the UPS that provides real-time information about its status, battery level, load, and alarms.
Audible Alarms: Sound alerts generated by the UPS to notify users of critical events such as power failures or low battery levels.
Automatic Shutdown Software: Software that allows the UPS to automatically initiate the shutdown of connected devices in the event of a prolonged power outage, ensuring data integrity and equipment protection.
