DC 48V input, AC 220V output,high-frequency inverter容量有： 500VA,1KVA,1.5KVA,2KVA,3KVA,4KVA,5KVA,6KVA---

1. The DC48V to AC220V sine wave inverter adopts CPU control, with a simple and reliable circuit; Intelligent power on/off, high degree of automation, easy operation;

2. Adopting SPWM pulse width modulation technology, the output is a pure sine wave with stable frequency and voltage, noise filtering, and low distortion;

3. The interface is friendly and uses LCD display: the working status, mains voltage, output voltage, battery voltage, frequency, load current, and other information are clear and understandable; And it has functions such as sound and light fault alarm and fault indication.

4. Built in bypass switch, fast switching between mains and inverter;

5. DC48V to AC220V sine wave inverters are divided into mains main supply type and battery main supply type:

A) Main supply type of mains power: When there is mains power, it is at the output of mains power, and automatically switches to inverter output when there is a fault in mains power input;

B) Battery main supply type: When there is mains power, it is in inverter output, and automatically switches to mains power output when there is a DC input fault;

6. The DC48V to AC220V sine wave inverter allows for cutting off DC and automatically switching to the mains bypass when turned on, without affecting the power supply to the load and facilitating maintenance and replacement of the battery;

7. If the battery voltage is too high or too low, the inverter power supply will turn off the output. If the battery voltage returns to normal, the power supply will automatically resume output;

8. When the load is overloaded, the inverter power supply will turn off the output. After 50 seconds of overload, the power supply will automatically resume output. This function is particularly suitable for unmanned communication base stations;

9. Support communication function (customized), provide RS232 interface (PIN2, 3, 5), and use monitoring software to real-time understand the power supply operation status; Provide two sets of passive dry nodes, one for DC input faults (RS232 PIN6, 7) and the other for AC output fault alarms (RS232 PIN8, 9)

10. Supports no DC startup function and can operate in a state with only mains power. This feature allows the inverter power supply to be put into use first, and then the battery can be installed.
