How to choose a power supply system for a communications station?The power supply system should meet the needs of the communications station, and its cabling should be as simple as possible to facilitate operation and maintenance. The low-voltage AC power supply system should use 3-phase 5-wire or 1-phase 3-wire for power supply.
What is the rated voltage of a communications power supply?Communications power supply devices and key constructions must be equipped with AC power supply with the rated voltage ranging from +10% to -15%. The frequency of the AC power current ranges from +4% to -4%, and the sinusoidal distortion rate of voltage waveform must be 5% or less.
What are the DC power supply specifications?Table A-9 lists the DC power supply specifications. The regulated voltage precision is less than or equal to 1% when the AC input voltage fluctuates between 85% and 110% of the rated voltage, the load current varies between 5% and 100% of the rated current, and the output voltage of the rectifier is any fixed value in the -46.0 V to -56.4 V ran
