| AC input voltage range |
88~264VAC; 124~370VDC |
| AC inrush current (max.) |
Cold start, 70A at 230VAC |
| DC adjustment range |
12V: 12~14V (only for SDR-75/120), 24V: 24~28V, 48V: 48~55V |
| Overload protection |
Normally works within 110%~150% rated output power for 3 seconds and then shut down output voltage with auto-recovery (re-power on to recover for SDR-75) |
| Overload protection |
>150% rated power or short circuit, constant current limiting with auto-recovery within 2 seconds and may cause to shut down if over 2 seconds |
| Over voltage protection Range |
14~17V for 12V model |
| Over voltage protection Type |
Shut down o/p voltage, re-power on to recover |
| Over temp. protection |
Recovers automatically after temperature goes down |
