6 Watt SMD and through hole DC/DC converters

Power-One Inc. 

Industrial Environment

DC/DC Converters < 40W

IMS6 Series

Cleaning Agents

In order to avoid possible damage, any penetration of

cleaning fluids has to be prevented, since the power sup-

plies are not hermetically sealed.

Protection Degree

The protection degree of the DC-DC converters is IP 30.

Isolation

The electric strength test is performed as factory test in ac-

cordance with IEC/EN 60950 and UL 1950 and should not

be repeated in the field. Melcher will not honour any guar-

antee claims resulting from electric strength field tests.

1 The front end output voltage should match the specified input voltage range of the DC-DC converter.

2 The earth connection has to be provided by the installer according to the relevant safety standard, e.g. IEC/EN 60950.

3 The installer shall provide an approved fuse (type with the lowest rating suitable for the application) in a non-earthed input line directly

at the input of the DC-DC converter (see fig.: Schematic safety concept). For UL’s purpose, the fuse needs to be UL-listed. See also:

Input Fuse.

4 Each suppressor diode should be dimensioned in such a way, that in the case of an insulation fault the diode is able to limit the output

voltage to SELV (<60 V) until the input fuse blows (see fig.: Schematic safety concept).

5 Has to be insulated from earth by double or reinforced insulation according to the relevant safety standard, based on the maximum

output voltage from the front end.
