DC/DC Converter - 48V/48V, 5 A, 240 W Reference Manual
Environment
Attributes Values Notes
Operational temperature -25…+70 °C (-13…+158 °F)
The operational temperature is the ambient or surrounding
temperature and is defined as the air temperature 2 cm
(0.79 in.) below the device.
Storage temperature -40…+85 °C (-40…+185 °F) For storage and transportation
Output derating
3.2 W/1 °C (3.2 W/1.8 °F) Between 45…60 °C (113…140 °F)
6 W/1 °C (6 W/1.8 °F) Between 65…70 °C (140…158 °F)
15 W/1000 m (15 W/3280 ft) or
5 °C/1000 m (9 °F/3280 ft)
For altitudes >2000 m (6562 ft), see Figure 20
Hardware does not control the derating. You must take this into consideration to stay below the derated
current limits to help prevent overloading the unit.
Humidity 5…95% r.H. According to IEC 60068-2-30. No condensation allowed.
Atmospheric pressure 110…47 kPa See Figure 20 for details
Altitude Up to 6000 m (19,685 ft) See Figure 20 for details
Degree of pollution 2 According to IEC 62477-1, non-conductive
Vibration sinusoidal
(1)
(1) Shock and vibration are tested in combination with DIN rails according to EN 60715, with a height of 15 mm (0.59 in.) and a thickness
of 1.3 mm (0.05 in.). These tests are performed with the DC/DC converter in standard mounting orientation.
2…17.8 Hz: ±1.6 mm (0.063 in.)
17.8…500 Hz: 2 g
2 hours / axis
According to IEC 60068-2-6
Shock
(1)
30 g 6 ms, 20 g 11 ms
3 bumps/direction
18 bumps in total
According to IEC 60068-2-27
LABS compatibility
As a rule, only non-silicon precipitating materials are used. The unit conforms to the LABS criteria and is
suitable for use in paint shops.
Corrosive gases
Compliant to ISA-71.04-1985, Severity Level G3 and IEC 60068-2-60 Test Ke Method 4 for a service life of 10
years, minimum, in these environments.
Audible noise Some audible noise can be emitted from the DC/DC converter during no load, overload, or short circuit.
