Specific Parameters
Electrical Parameters
Input Specifications:Voltage Range: 90-264V AC (47-63Hz) or 130-350V DC, wide voltage compatibility design for global power standardsMaximum Input Current: ~1.2A at 230V AC (full load), ~0.8A at 300V DC (full load)Power Factor: >0.95 (with active PFC), reducing grid harmonic pollution and improving energy efficiencyInrush Current: <50A during cold start (230V AC), protecting upstream circuits
Output Specifications:
| Output Voltage | Rated Current | Power Allocation | Precision | Ripple & Noise |
|---|---|---|---|---|
| +5V DC | 28A | 140W | ±1% | <10mVpp |
| +12V DC | 7A | 84W | ±1% | <15mVpp |
| -12V DC | 0.5A | 6W | ±2% | <20mVpp |
| Total Power | – | 224W | – | – |
Note: MPS022/15 version outputs +5V(28A)/+15V(5.6A)/-15V(0.5A), total power 224W
Protection Functions:Overvoltage Protection (OVP): Triggered when +5V output >5.5V, +12V output >13.2V, -12V output <-13.2VOvercurrent Protection (OCP): Independent current limiting for each output channel, automatically shuts down output in short circuitOverheating Protection (OTP): Derates output when internal temperature >85℃, shuts down when >95℃Under Voltage Lockout (UVLO): Does not start when input voltage <85V AC or <120V DC, preventing operation under low voltage
