Linear Power supply for radio base station

Linear power supply for radio base station (Fixed station transceivers) Features: SD1731/1732W2 (linear) 1) Input voltage: AC 187V - 242V/110VAC 2) Output voltage: DC 13.8V 3) Output current: 10A / 15A 4) Output ripple: ≤10mVp-p 5) Charge current: 2A / 1A 6) Output over current, over voltage protection 7) Automatically switch to battery supplys while mains power loses(battery back-up function) SD1733/1734W5 (linear) 1) Input voltage: AC 187V - 242V/110VAC 2) Output voltage: DC 13.8V 3) Output current: 25A / 30A 4) Output ripple: ≤15mVp-p 5) Charge current: 5A / 1A 6) Output over current, over voltage protection 7) Automatically switch to battery supplys while mains power loses(battery back-up function) Product features:1) Output voltage and output current and charge state display2) High precision and regulated voltage, the regulated voltage precision coefficient less than 0.1%3) Over voltage protection automatically, if output voltage is higher than normal output voltage range, it will cut off the power automatically so as to ensure the safe of the station. 4) Over current protection automatically, if output current is higher than Max. current or short circuit, it will cut off the power automatically.5) Pulse current charging with fast and float charging and switch automatically.6) Wide voltage range4) If there has mains power, the power supply will charge for the battery, if there has no mains power, the battery will supply to the power supply automatically.( Battery backup function)
