nJoy Echo Pro 1000

The nJoy Echo Pro 1000 UPS with online double-conversion topology delivers an apparent power of 1000VA and a real power of 800W. It generates a pure sine wave output, which is essential for operating sensitive electronics and devices with motors. Thanks to the double-conversion principle, where the UPS converts the incoming AC voltage to DC and back to AC, it provides a higher level of protection against mains power anomalies. The UPS switches to battery power with zero delay (0ms). A wide input voltage range of 80–300V reduces the need to switch to the battery, extending its lifespan. At half load, it powers connected devices for 6 minutes.

Online topology and constant power

The UPS operates on the principle of online double-conversion topology. This technology continuously regenerates power with zero transfer time to the battery, delivering a pure sine wave output voltage with low harmonic distortion (≤ 3% THD at linear load). A wide input voltage range from 80V to 300V reduces the frequency of transfers to battery power, thus extending the life of the internal batteries. Automatic Voltage Regulation (AVR) maintains a stable output with ±1% accuracy in battery mode. The efficiency in mains AC mode reaches 88%, in battery mode 85%, and in the power-saving ECO mode it reaches up to 96%.

Battery and backup

The UPS contains two GP07122L batteries, which recharge to 90% capacity in approximately 4 hours. The unit powers connected devices at a full load of 800W for 1 minute, at a half load of 400W for 6 minutes, and at a quarter load of 200W for 19 minutes. The ECO mode optimises consumption, where the operating efficiency increases to up to 96%. In this mode, the UPS powers the appliances directly from the mains, bypassing the double conversion as long as the input voltage is within tolerance. If an anomaly is detected, it switches back to online mode within 4ms.

Advanced protection and quiet operation

The UPS integrates surge protection rated at 220J and multi-stage overload protection. In mains mode, it switches to bypass after 60 seconds at 110–120% overload, and immediately at loads above 120%. In battery mode, it shuts down after 10 seconds at 110–120% overload. The cold start function allows it to start from the battery when no mains power is present. A clear LCD display shows the load status, battery charge level, operating modes, and any error codes. The included PowerGuide software performs an automatic safe shutdown of connected systems during a prolonged power outage and displays detailed information about the UPS status, input/output voltage, and battery health. The noise level of the UPS does not exceed 40dB, ensuring it doesn't disturb the working environment with excessive sound.

Connectivity and outlets

The HID USB communication interface, RS232 port, or internal slot for an optional SNMP card enable remote management and monitoring over the network. It offers three Schuko-type output sockets for connecting appliances. All three sockets provide full battery backup and surge protection.
