nJoy Echo Pro 3000

The nJoy Echo Pro 3000 UPS uses on-line double-conversion topology, delivering an apparent power of 3000VA and a real power of 2400W. This technology generates a stable, pure sine wave output voltage, which is essential for the safe operation of servers, workstations, and other sensitive electronics. The system features zero transfer time when switching to battery in on-line mode, eliminating any power interruptions. At half load, it keeps connected devices running for 7 minutes. A wide input voltage range of 80–300VAC reduces the frequency of switching to battery power during grid instability.

Topology and performance

This UPS is built on an on-line topology. Its double-conversion technology completely isolates your appliances from power grid anomalies and delivers a pure sine wave output voltage. The UPS operates with a real power of 2400W. In normal AC mode, it achieves an efficiency of 88%, which increases to 96% in the energy-saving ECO mode. The wide input voltage range of 80–300VAC reduces the need to switch to battery. In on-line mode, it transfers to battery power with zero delay.

Battery and protection

Six GP07122L batteries provide power during an outage. Recharging to 90% capacity takes approximately 4 hours. The backup time ranges from 18 minutes at a quarter load to 1 minute at full load. The integrated overload protection system actively prevents damage to both connected devices and the UPS itself. The input circuit protection absorbs energy spikes of up to 565J.

Advanced management and connectivity

For IT infrastructure integration and management, it uses several communication interfaces. It offers a HID USB port, an RS232 serial port, an Emergency Power Off (EPO) connector, and a slot for an optional SNMP card. The included PowerGuide software for remote monitoring and configuration supports automated safe shutdown of servers. The clear LCD display shows all operating statuses, such as load level, battery capacity, or the current mode. Audible alarms alert you to status changes or potential faults. For connecting appliances, it uses four Schuko output sockets as well as hardwire terminals for a permanent connection of critical infrastructure or devices with higher consumption.
