Capacity: 1KVA-15KVA Inverter
Features: N+X redundant parallel technology; Direct use of the original DC system; Realize Online design through Relay + SCR compensation; AC and DC dual circuit input structure.
Description: XMI Series 48Vdc Inverter for Telecommunication is a new generation of dual-input inverter solution designed by Evada for communication applications, which is suitable for the high-reliability power supply requirements of communication systems. This solution is equipped with a 220V AC power supply and a 48V DC power supply, which can flexibly set the priority of the input main power supply according to the application scenario. Use the communication station -48Vdc power supply system, share the storage battery, and output 220Vac sine wave power supply.
Front:
Note: There is no 48Vdc output for XMI Series. If you need a rectifier module to charge the battery pack and 48Vdc output, please choose XMI-HR Series.

Working Principle:
Performance Characteristics:
Unique suppression technology for reflected noise
1. Through the unique pre-filter design, the impact, surge, sag, and noise interference to the power grid are eliminated.
N+X redundant parallel technology
1. High reliability
2. The system does not require any additional parallel cabinet
3. Parallel operation is realized by the internal microprocessor.
4. Adopts non-master-slave current sharing mode with high-precision load sharing.
Intelligent monitoring interface
1. With RS485/RS232 interface or optional SNMP for remote monitoring.
Direct use of the original DC system
1. Save investment and reduce maintenance costs.
2. Provide long backup runtime for the loads.
Online design
1. Relay + SCR compensation: inverter’s functional switch will never cause loads’ sudden power failure.
AC and DC dual circuit input structure
1. Provide pure power and complete protection for critical loads without increasing the capacity of the rectifier.
Application
Indoor distributed base stations for Telecom operators, network optimization, outdoor remote coverage, specialized network computer room systems for railway, post, public security, etc.
