| DC input |
113–370 VDC. |
| AC inlet |

Use a suitable approved mains lead for the C8 inlet. Confirm whether the order includes the mains lead; the catalogue does not specify an AC cord as included.
Medical Isolation and Application
| Isolation design |
2 × MOPP primary-to-secondary isolation and a BF-rated design. |
| BF application |
BF-rated adapter design with the listed home-healthcare standards. |
| Touch current |
<100 µA at 264 VAC. |
| Primary-to-secondary withstand |
4 kVAC. |
| Insulation resistance |
Input/output: 100 MΩ at 500 VDC, 25°C and 70% RH. |
MOPP stands for means of patient protection. The isolation and leakage ratings support medical-equipment design; they do not by themselves certify the complete medical device or its patient connections. Verify the required applied-part classification, installation and system-level safety for the actual equipment.
Protection
| Overload / short circuit |
Overload threshold 105–150% of rated output power; hiccup mode, with automatic recovery after the fault is removed. |
| Overvoltage |
105–135% of rated output voltage; output shuts down and requires re-powering. |
| Overtemperature |
Output shuts down; re-power after temperature has returned to a safe level. |
Cooling, Derating and Environment
| Operating ambient |
−30 to +70°C, subject to derating. |
| Horizontal temperature curve |
100% load from −30°C through 40°C; the curve marks 80% at 50°C and 50% at 70°C. |
| Input-voltage derating, 60 Hz |
80 VAC: 80% load; 100 VAC: 100% load; 264 VAC: 100% load. |
| Operating humidity |
20–90% RH, non-condensing. |
| Storage |
−40 to +85°C; 10–95% RH, non-condensing. |
| Temperature coefficient |
±0.03%/°C over 0–40°C. |
| Operating altitude |
Up to 3000 m. Above 2000 m, reduce the operating ambient-temperature limit by 3.5°C per additional 1000 m for this fanless adapter. |
| Vibration |
10–500 Hz, 2 G; 10 minutes per cycle and 60 minutes along each X, Y and Z axis. |
Apply input-voltage and temperature derating together. Use the horizontal orientation of the catalogue curve and provide ventilation around the case. Do not interpret the 70°C ambient endpoint or the 3000 m altitude as an unconditional full-power rating.

Stripped and tinned leads are available by request: group 1 is +Vo, with red/blue shown; group 2 is −Vo, with black/white shown. Colours are reference only and must be checked on the actual product. The standard drawing marks L = 25 mm and L1 = 5 mm; both lengths can be specified by request. This option has no separate complete order code printed.
Connector names above identify the catalogue cable configurations or named equivalents. Confirm the mating side, connector orientation, polarity and equipment clearance when ordering; these items are not a promise that a mating socket or custom plug is included.
