II. OUTPUT CHARACTERISTIC
2-1. Output voltage and current
Output voltage | Error Range | Output Current | |
48VDC | ±0.1% | MIN | MAX |
0A | 6.25A | ||
12V (optional/optional) | ±0.1% | 0A | 2A |
2-1 Load Regulation
Under the conditions of AC input voltage, output load current, and ripple noise changes, the rate of change of output voltage should be within ± 0.5% of the rated output voltage.
2-3. Ripples and noise
Output voltage | Ripple and noise |
48VDC | 260mV (MAX) |
Explanation: The ripple test is conducted at a frequency range of 20MHz and room temperature of 25 ℃ on the oscilloscope, and a 10uF/50V electrolytic capacitor and a 0.1uF/50V ceramic capacitor are connected in parallel at the output end
2-4. Overvoltage protection
When the output voltage is higher than 10% of the rated output voltage, the machine will enter a protective state and can resume normal operation after returning to the rated output voltage
2-5. Overcurrent protection
When the working current of the machine is greater than 7A, the power supply will operate in constant current mode.
2-6. Short circuit protection
When the machine is operating normally (with normal input voltage and load), a short circuit at the output end will not cause damage or safety issues to the machine itself, and the machine can resume normal operation after the short circuit is cancelled
2-7. Leakage current
When the input voltage is 264Vac 50Hz, the leakage current should be ≤ 3.5mA
