Select the complete model, output voltage, current capacity, connector and polarity for the load. A matching connector shape alone does not establish electrical compatibility.
Output Ratings
Nominal output

Rated current
13.4 A.
Output current range
0–13.4 A.
Rated output power, maximum
201 W.
Ripple and noise, maximum

Voltage tolerance
±5.0%.
Line regulation
±1.0%.
Load regulation
±5.0%.
Efficiency, typical
90% for this R7B version.
Observe the stated current and power limits together. Unless otherwise specified, measurements use 230 VAC, rated load, 25°C and 70% RH. Voltage tolerance includes set-up tolerance, line regulation and load regulation. Line regulation is measured from low to high input at rated load.
Ripple and noise are measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors.
The output-voltage set point is measured at the DC plug terminals with 50% load.
Input and Timing
AC input
85–264 VAC; 47–63 Hz.
DC input
120–370 VDC.
Power factor, typical
PF >0.91 at 230 VAC and PF >0.98 at 115 VAC, at full load.
AC current, typical
4 A at 115 VAC; 2 A at 230 VAC.
Cold-start inrush, maximum
95 A at 115 VAC; 120 A at 230 VAC.
Set-up / rise time
2000 ms / 50 ms at 230 VAC; 2000 ms / 50 ms at 115 VAC, at full load.
Hold-up time, typical
20 ms at both 230 VAC and 115 VAC, at full load.
Leakage current, maximum
0.75 mA at 240 VAC.
Set-up time is measured at the first cold start. Repeated power switching may increase the set-up time. Apply the low-input derating curve.
Protection
Short circuit / overload
105–135% of rated output power. Hiccup mode; automatic recovery after fault removal.
Overvoltage
105–135% of rated output voltage. Hiccup mode, specified at 10% load.
Overtemperature
Output shutdown; automatic recovery after the temperature decreases.
Cooling and Environment
Working ambient
−30 to +70°C, subject to the model-specific derating curves.
Temperature derating
Horizontal installation: at 230 VAC, full load through 50°C. At 110 VAC, full load through 40°C. Both curves decrease to 50% at 70°C.
Input-voltage derating
At 60 Hz, 60% load at 85 VAC, rising to 100% at 100 VAC. Full load is then available through 264 VAC, subject to temperature derating.
Working humidity
20–90% RH, non-condensing.
Storage
−40 to +85°C; 10–95% RH, non-condensing.
Temperature coefficient
±0.03%/°C over 0–50°C.
Vibration
10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each X, Y and Z axis.
Altitude derating
Above 2000 m, reduce permissible ambient temperature by 3.5°C per 1000 m for fanless operation.
Keep the adapter unobstructed and apply both input and temperature limits. The plotted operating-temperature range is not a full-power guarantee at every input voltage.
