nJoy Keen 800
nJoy Keen 800
The nJoy Keen 800 UPS operates as a line-interactive UPS with an apparent power of 800VA and a real power of 480W, making it a reliable solution for PCs, workstations, and other sensitive electronics. With its line-interactive topology and Automatic Voltage Regulation (AVR), it actively stabilises mains fluctuations without needing to switch to battery power. This AVR UPS adjusts voltage within a wide range of 162 to 290VAC. In battery mode, it provides a simulated sine wave output, suitable for powering devices with switched-mode power supplies. At half load, it powers connected devices for 3 minutes, giving you enough time to save your work and shut down the system correctly. The compact tower design and low operating noise of under 40dB make it easy to place the nJoy Keen 800 UPS directly in your office or home study.
Key features of the nJoy Keen 800 UPS
- Uses line-interactive topology with Automatic Voltage Regulation (AVR)
- Provides a simulated sine wave output in battery mode
- Offers a cold start function to power on without mains electricity
- Ensures overload, overvoltage and short circuit protection
- Protects the battery against deep discharge and overcharging
- Automatically restarts after mains power is restored
- Includes two Schuko backup output sockets
- Compact tower design with low noise level
Topology and performance
The line-interactive connection stabilises the output voltage without switching to the battery across a wide range of input voltages. The source provides sufficient 800VA / 480W power for stable operation of connected devices. When running on battery, it provides a simulated sine wave with a typical switching time of 4ms. The backup time at 50% load is 3 minutes, dropping to under one minute at full load.
Battery and protection features
Inside the unit is a single GP09122L battery cell, which recharges to 90% capacity in 6 hours. The source supports a cold start function to power up without the mains, allowing you to power your devices even during a complete outage. The circuit breaker and electronic circuits provide complete protection against overload, overvoltage, short circuits, and both deep discharge and overcharging of the battery.
Automatic functions and connectivity
Several automatic features simplify operation. The integrated Automatic Voltage Regulation (AVR) stabilises mains fluctuations without using the battery. The Auto-Restart function ensures an automatic resumption of operation after power returns, and Auto-Charge keeps the battery ready at all times. Charging also occurs when the unit is turned off thanks to the Off-Mode Charging feature. An integrated 1.2m power cable connects it to the mains. For output, the source offers two Schuko sockets that provide full battery backup and surge protection.
