Overview

Main features of air conditioning dedicated inverter: DLN48-3K communication inverter power supply meets the national standard IEC146-4

Product Details

Air conditioning dedicated inverterKey Features:

The DLN48-3K communication inverter power supply complies with the national standard IEC146-4, the People's Republic of China standard GB7260, the power maintenance regulations of the Ministry of Information Industry of the People's Republic of China, and the implementation rules for quality certification and inspection of communication inverter equipment entering the network. It is manufactured according to the postal and telecommunications power supply system of the People's Republic of China and can be used as an inverter power supply equipment for various occasions such as postal and telecommunications, railways, ships, etc. It is suitable for uninterrupted AC power supply occasions such as Chinese character telegraph machines, telegraph terminals, wireless paging equipment, data switches, local telephone switches, microwave communication equipment, program-controlled switch billing systems, graphic fax machines, and various AC instruments and computer equipment.

Air conditioning dedicated inverter容量有： 500VA,1KVA,1.5KVA,2KVA,3KVA,4KVA,5KVA,6KVA---

1Air conditioning dedicated inverterAdopting CPU control, the circuit is simple and reliable; 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;

5Air conditioning dedicated inverterMain power 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. 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. 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.
