5.0Operation

5.1Modes of operation

The UPS operates in one of five modes—sleep, standby, on-line, on-battery, and bypass-depending upon the condition of the UPS, the batteries, the loads, and the input mains voltage.

5.1.1 Sleep mode

In sleep mode, the UPS’s display is inactive and no voltage is present at the output. The UPS is put to sleep manually when commanded “Off ” by the user. The UPS automatically enters sleep mode after 5 minutes with no commands given while in standby mode (see following section). After 5 minutes, the UPS enters sleep mode from on-battery mode when shut down because of battery exhaustion or overload, to conserve battery capacity. Press any front-panel button to “awaken” the UPS.

Some versions of PowerChute plus allow remote users to put the UPS to sleep and awaken it after a set interval.

5.1.2 Standby mode

While in standby mode, the UPS’s display and control interface is active, but no voltage is present at the output. The UPS enters standby mode when first “awakened” from sleep mode.

5.1.3 On-line mode

Once commanded to power the loads, the UPS is normally in on-line mode. While in this mode the UPS delivers power derived from the mains to the loads, maintains proper battery charge, regulates the output voltage to within a narrow band, and isolates the load from surges and electrical noise brought by the service wiring. A multilevel transformer tap changing circuit provides this regulation and isolation while maintaining extremely high efficiency. When adjusting the load voltage, the UPS temporarily operates the load from battery power while it makes an appropriate transformer tap change. Remote on-battery signaling is disabled during a tap change. The UPS’s display indicates the percent of rated load applied at the output when operating on-line.

5.1.4 On-battery mode

When in on-battery mode, the UPS supplies load power derived by the UPS’s inverter from the Battery Packs. The voltage waveshape delivered in on-battery mode is a low-distortion sine wave. While on-battery, the UPS regulates the output voltage and frequency to within a narrow band. The UPS operates in on-battery mode during the user-defeatable start-up or scheduled battery tests. The UPS operates on-battery when the line voltage or frequency has fallen outside the limits given in the Specifications section or has become extremely distorted by, for example, noisy adjacent service branch loads or an overburdened fuel generator source.

3000, 5000 specifications

American Power Conversion (APC) has long been a leader in the manufacturing of uninterruptible power supplies (UPS), and among its range of products, the APC 5000 and 3000 series stand out for their robust performance and reliability. These UPS systems are designed to ensure a continuous flow of power, protecting sensitive electronic equipment from fluctuations and outages.

The APC 5000 and 3000 models boast a range of key features that make them suitable for both commercial and residential applications. One of the primary characteristics is their high power capacity. The 5000 model provides a substantial 5000VA/4500W output, while the 3000 variant offers 3000VA/2700W. This enables users to connect multiple devices and critical loads without the risk of overload.

Both models utilize advanced double conversion technology, which ensures that the output power is consistently clean and stable. This technology is crucial for sensitive electronics, as it filters out voltage irregularities, providing pure sine wave output. This characteristic is particularly important for equipment like servers, data centers, and networking hardware, as it enhances their longevity and operational efficiency.

Another notable feature is their extended battery runtime capability. The APC 5000 and 3000 units are designed with hot-swappable batteries, allowing for easy replacement without interrupting the power supply. This enhances the overall reliability of the system, ensuring that even during maintenance, equipment remains operational.

In terms of connectivity, both models come equipped with multiple outlets for various plug types, as well as USB and network ports for monitoring and management. The integration with APC's PowerChute software allows users to manage power preferences, monitor battery health, and receive alerts when attention is needed. This level of monitoring is essential for facilities management teams, allowing them to ensure continuous operations without power-related disruptions.

The APC 5000 and 3000 also feature robust thermal management systems. With built-in fans, these units ensure efficient airflow and heat dissipation, protecting internal components from damage due to overheating.

In conclusion, the APC 5000 and 3000 series represent a powerful solution for those seeking reliable power protection. With their advanced technologies, multiple connectivity options, and serviceability features, these UPS systems stand out as trusted components in any power management strategy. Whether in a data center or a home office, the reliability and efficiency of these models make them invaluable in today’s power-dependent environment.
