DJN series inverters adapt to telecom systems with 48VDC power supply, adopting high efficiency SPWM inversion technology. DJN series inverter can be connected to teleprinter, telegraph terminal, wireless paging equipment, data switching exchange, local exchange, microwave communication equipment, program controlled exchange charging system, fax machine and all kinds of AC instrument, computer equipment and various communication equipment. Meanwhile, DJN-K Series inverter can be used for air conditioner, such as 3KVA for 1.5P and 5KVA inverter for 3P air conditioner.
MainFeatures:
l Compliant with communication standard of AC and DC power supply system
l High performance SPWM inversion technology
l Wholesome protective measures
l Low DC end current noise
