| Weight | 0.85 | kg |
| Case materials | Steel (cover), aluminum (heat sink) |
¹) Wall mounting tabs are fixed part of enclosure
Environment
| Property | Value | Units |
|---|---|---|
| Operating temperature | 10-70 | °C |
| Storage temperature | -30-90 | °C |
| Humidity | 0-95 non-condensing | % |
| Power dissipation | 2-100¹ | W |
¹) Power dissipation is output current and input voltage related.
Power supply
| Supply² | Input voltage | Input current typ | Input current max |
|---|---|---|---|
