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.
Main features:
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
overvoltage 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. |
