Note 1: When the voltage is output, the maximum output load current is 500mA.
Note 2: When the current is output, the maximum load resistance that the output can carry can be calculated by
Ohm's law.For example, the power supply of 500mA output is 24V, and the maximum output resistance is
24V/0.5A=48 Ω. The load exceeding this resistance will make the current less than 500mA.
Note 3: For conventional products with two isolated outputs, the power supply negative and output signal
negative cannot be shorted.
