SANUPS Power Supplies present a good 2kVA/1400W hybrid UPS, which mixes line interactive functions together with double conversion technology. It is unique because it gives three different ways it can work, so it is reliable and it saves energy. This single-phase system uses 208V for both input and output. It is built strong, with parts such as solid-state inverter and rectifier. It also has battery charger together with a static switch that can always works. The machine can handle different AC input that goes from 167V to 239V (that is -20%/+15%). It also works with both 50Hz and 60Hz, and can pick the right one automatically. It is made in a way that keeps the output voltage steady (±2%). The frequency can be changed between ±1%, ±3%, or ±5%. When it is running freely, it ensures frequency stays accurate at ±0.5%. Batteries are very important, with a system using 48V batteries that can be changed while the machine is on. They can last for a long time; like up to 87 minutes when not using too much power and 5 minutes when using full power. The battery system is smart, checking batteries automatically or by hand. Additionally, it protects against too much voltage, also watches the battery life, warning when the battery is getting old. The machine has 13 lights that show what is happening, like what mode it is in, how much power is used. These lights also show battery status, along with if there are any problems. People can use three buttons on front to control the inverter along with check the battery. It can connect using RS232 with a DB9 connector. There is also a spot for adding things like LAN cards that use SNMP, SMTP, and web interface. It protects itself in many ways like changing to bypass automatically when there is too much power. Furthermore, it can handle short circuits, and watches the temperature. It can work when it is 0-40°C, up to 2000m high without losing power.
