Voltage stabilization accuracy

Source effect: ≤0.2% rated value (output voltage change rate caused only by input source voltage change ± 10%)

Time drift: ≤0.2% rated value (only due to the output voltage change rate caused by the power supply working continuously for more than 8 hours)

Load effect: ≤0.2% rated value ± 2 digits (output voltage change rate caused only by the output current changing from zero to the rated value)

Current stabilization accuracy

Source effect: ≤0.1% rated value (output voltage change rate caused only by input source voltage change ± 10%)

Time drift: ≤0.3% rated value (only due to the output voltage change rate caused by the power supply working continuously for more than 8 hours)
