What is the output of this group? If the power supply to the 48V, is not +24 V termination of the electrical 48V + input, -24V termination of the electrical 0? is this okay? Voltage difference is 48V ah? Thank you very much!
When the positive ground, then the voltage is -24V, because the earth is zero potential surface
Generally speaking, can be used for DC48V power supply, but note that some switching power supply + - output current is different, to check the product manual.
Any voltage is relative to the reference point, +24 V relative to the ground potential difference is 24V, and for -24V is 48V
Then -24V to the ground as a reference point is -24V
But note that some switching power supply + - output current is different, to check the product manual.
24V and -24 V voltage difference is 48V, then it is the same power can be used when the 48V power supply to pay attention to electrical power
A simple description of the source of the 24, with two batteries in series with the negative side of the voltmeter connected to the midpoint of the series, the positive measurement of the two ends of the battery, you get a positive 1.5V and a negative 1.5V voltage
