When reviewing the ZD10-100 datasheet, how does it stack against similar 100W supplies (e.g., Mean Well LRS-100-12, Delta PMT-12V100W)? zd10-100 datasheet
| Feature | ZD10-100 | Mean Well LRS-100-12 | |---------|----------|----------------------| | Efficiency | 87% | 88% | | Hold-up time | 16 ms | 10 ms | | Operating temp | -20°C to +70°C | -25°C to +70°C | | Ripple | 120 mV | 100 mV | | Price bracket | Mid-range | Budget | Mean Well LRS-100-12
The ZD10-100 excels in hold-up time (critical for industrial grids) and typically offers better EMC filtering. zd10-100 datasheet
Internal sensor trips at ~85°C case temperature. The power supply shuts down and automatically restarts when cooled to 65°C.
