Applicable to such systems as post and telecommunication, railroad, ship transportation etc.where 48Vdc power supply is supplied. Serving as regulated power supply for system terminal computer, stored program exchange and so on that require good power supply. It can be connected to Chinese character 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.
Compliant with communication AC and DC power supply system standards; The main unit may directly use power to AC/DC power for power supply. The main unit directly inverts -48V to 220Vac sine wave. DC current noise, after being handled, will not affect other telecommunication equipment's operation, which complies with relevant standards of the Ministry of Information Industry.Wholesome protective measures: Such functions are designed as output over-voltage protection, overload, electronic current limiting and short current protection, so as to avoid malfunction conducted by personnel misoperation. High-performance PWM inversion technology: High-performance PWM inversion technology is adopted. DC input:48Vdc, and AC output: 220 Vac. Low DC end current noise: Professional noise reduction measure is adopted. Low in DC end current noise. Compliant with communication industry standard.
