19 Inch Rack Mount Industrial Power Inverter 48v to 380v 3kw Telecom Parallel Inverter Inverters & Converters

Main characteristics of inverter 48v to 380v 18kw

1. Embedded installation design, supporting the national standard 19 inch rack mounted installation method and the mobile portable box installation method;

2. Adopting CPU control, the circuit is simple and reliable; Intelligent power on/off, high degree of automation, easy operation;

3. Adopting PWM pulse width modulation technology, the output is a pure sine wave with stable frequency and voltage, filtered out noise, and low distortion;

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

5. Divided into main power supply type, battery main supply type, and pure reverse 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 the battery is normal, it is in inverter output, and when the DC input fails, it automatically switches to mains output;

C) Pure inverter variant: not connected to AC mains power, pure inverter operation, supports long-term on load inverter operation;

6. It is allowed to cut off the DC and automatically switch to the mains bypass when the device is turned on, without affecting the power supply of the load, making it convenient to maintain and replace 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. Support communication function (RS485 communication interface or customized other interfaces):

RS485: Standard Modbus communication protocol, RS485 communication interface, RJ45 crystal port with 1 pin 485A and 2 pins 485B from the left

9. Supports no DC power on function and can operate in a state of only mains power. This feature allows the inverter power supply to be put into use first, and then the battery can be installed. (Machines set to parallel mode must be powered on with DC power)

10. The container shell of the mechanical and electrical unit is made of metal material and meets the anti vibration and service life requirements of the inverter power supply when moving in various environments;
