Rated output power	3 W.
Typical efficiency	82% at nominal input and rated load, 25°C and 70% RH.
Maximum capacitive load	470 µF.
Voltage accuracy	±2%.
Ripple and noise	50 mVp-p. Measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Line regulation	±0.2%, measured from low input to high input at rated load.
Load regulation	±0.5%, measured from 10% to 100% rated load.
Switching frequency	100 kHz typical.

Input and protection

Input voltage	36–75 V DC; 48 V DC nominal.
Input-range reference	Use the 36–75 V DC range stated in the model encoding and selection table. The common specification row gives a different lower limit; confirm the supplied ratings before operation outside 36–75 V DC.
Input current	7 mA at no load; 76 mA at full load.
Input surge voltage	100 V DC for 100 ms maximum.
Input filter and fuse	Internal capacitor filter. An external 200 mA slow-blow fuse is recommended.
Internal power dissipation	1000 mW.
Undervoltage lockout	Start-up voltage: 34 V DC. Shutdown voltage: 30 V DC.
Short-circuit protection	Continuous short-circuit protection with automatic recovery.
Overload protection	150–250% of rated output power; recovers automatically after the fault condition is removed.

Environment and cooling

Cooling	Free-air convection.
Operating temperature	−40°C to +85°C, subject to the load derating curve.
Load derating	Natural convection: 100% load through +71°C, reducing to 50% at +85°C. The plotted tail beyond +85°C does not extend the specified operating-temperature range.
Maximum case temperature	+100°C.
Working humidity	20–90% RH, non-condensing.
Storage temperature and humidity	−40°C to +105°C; 10–95% RH, non-condensing.
Temperature coefficient	0.03%/°C from 0°C to +80°C.
Vibration	10–500 Hz, 2G; 10 minutes per cycle, for 60 minutes along each of the X, Y and Z axes.
