For -48V system equipment, the required operating voltage range is -38. But unlike traditional 12 and 24 volt systems which have the minus (-) side of the battery connected to ground (i. This design is targeted for telecom applications because this negative supply voltage is used with the most common of telecom. . Telecom and wireless networks typically operate on -48 VDC power, but why? The short story is that -48 VDC, also known as a positive-ground system, was selected because it provides enough power to support a telecom signal but is safer for the human body while doing telecom activities (such as. . Today it is generally accepted by safety regulations and electrical code that anything operating at or below 50V DC is a safe low-voltage circuit, and -48VDC is still the standard in communications facilities serving up both wired and wireless services. In fact, -48VDC allows telecom operators to. . Products basically use -48V power supply system, and the actual measured voltage is generally –53. This is because for reliability reasons, communication equipment is equipped with a backup battery (-48V). the negative line is used as the ground –. .
