UPS
UPS (Uninterruptible Power Supply) is a device designed to provide continuous power to connected equipment in the event of a power outage. It acts as a backup power source, ensuring that critical systems and devices can continue to operate without interruption.
An uninterruptible power supply or uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries, supercapacitors, or flywheels. The on-battery run-time of most UPS systems is relatively short (only a few minutes) but sufficient to start a standby power source or properly shut down the protected equipment.
- Operation: In normal operation, the load is directly connected to the mains power supply. When a power outage occurs, the UPS switches to battery backup.
- Pros: Cost-effective and simple to install.
- Cons: Can have a brief power interruption during the transfer time between mains and battery.
- Provides immediate backup power when the mains power fails.
- Helps stabilize voltage fluctuations that can damage sensitive equipment.
- Protects against sudden voltage spikes that can cause equipment damage.
- Generally more affordable than online UPS systems.
- Can be more energy-efficient in some operating conditions.
- Fewer components reduce maintenance and repair costs.
- Ideal for applications where a brief power interruption is acceptable.
- A cost-effective solution for businesses with limited budgets.
- Can be used as a temporary power source during construction or renovation.
Online UPS
Online UPS protects your mission critical applications from downtime, data loss and corruption that inevitably hamper your productivity. The Online UPS range is designed to fit perfectly into any given environment where uninterrupted power feed is required to secure and ensure continuous operations.
- Operation: The load is always supplied power through the UPS’s inverter, even when the mains power is available. The inverter converts the incoming AC power to DC, stores it in batteries, and then converts it back to AC for the load.
- Pros: Provides continuous, clean power with zero transfer time, making it ideal for critical systems like servers and medical equipment.
- Cons: More expensive and complex than offline UPS systems.
- True double-conversion Online UPS
- Microprocessor control for higher reliability
- Input power factor correction
- Wide input voltage range (110 V – 300 V)
- Generator compatible
- Selectable charging current - allows flexibility to add any battery size
- Automatic bypass
- Emergency Power Off (EPO)
Both UPS and Online UPS types offer protection against power outages, but online UPS systems provide higher reliability and protection for critical applications. The choice between offline and online UPS depends on the user’s specific needs and budget.
