nJoy Aira 600
The nJoy Aira 600 backup power supply is a line-interactive UPS that powers appliances requiring a stable voltage. It provides 500W of real power and 600VA of apparent power. Thanks to its external battery design (battery not included), the user can choose a capacity from 40Ah to 200Ah, which determines the length of the backup time. This approach is ideal, for example, for backing up central heating circulation pumps. A key feature is the pure sine wave output, which protects sensitive electronics and motors. The clear LCD display shows the current status, input and output voltage, and load level. The operating noise does not exceed 40dB.
Key features of the nJoy Aira 600 backup power supply
- Provides a pure sine wave to protect sensitive appliances
- Uses line-interactive topology with Automatic Voltage Regulation (AVR)
- Connects to external batteries with capacities from 40Ah to 200Ah
- Lets the user choose a charging current of 10A or 20A
- Includes a cold start function for operation without mains power
- Built-in LCD display shows the current device status
- Ensures quiet operation with noise levels below 40dB
Topology and power
This power supply uses a line-interactive topology and provides 500W of real power with an apparent power of 600VA. The Automatic Voltage Regulation (AVR) function stabilises the output voltage between 145V and 275V without switching to battery power. In battery mode, it maintains an output voltage accuracy between 213V and 248V. An automatic restart function restores operation once mains power returns. The supply uses an external 12V Car or Deep-cycle battery with a recommended capacity of 40Ah to 200Ah. The user can choose between two charging currents: 10A for gentler charging or 20A for faster capacity recovery. The cold start function starts the UPS directly from the battery without a mains connection. Integrated protection shields the device from overload and short circuits, and charging occurs even when the unit is switched off.
Design and connectivity
The unit features a Tower design with dimensions of 120 × 290 × 255mm and a weight of 7.6kg. This design makes it easy to place near the protected equipment, such as a central heating boiler. The operating noise level does not exceed 40dB, contributing to quiet operation in a home environment. The package includes a practical adapter for connecting to a car battery, expanding the power supply's use beyond standard installations. Two Schuko output sockets, both fully battery-backed, are available for connecting appliances.
