Approvals
Each device must comply with the safety directives of the country in which the device is
intended to be used. For power supply units this, for example, applies to the device safety,
which is defined by EN 60950 in Europe, by UL 60950 in the USA and by CSA-C22.2 in
Canada.
For industrial applications, compliance with EN 50178 is often required in Europe and with
UL 508 in the USA.
With the CE certification the manufacturer guarantees that the device is being developed,
produced and sold according to the applicable directives of the European Union.
Particularly for power supply units compliance with the low voltage directive and the EMC
directive is required.
Further approvals not being required by law underline additional safety: In Germany, the
approval "Gepr ü fte Sicherheit (GS)" (approved safety) provides an additional safety
certification for devices. The approval "Germanischer Lloyd (GL)" (German Lloyd) certifies
maximum reliability under extreme climatic conditions and maximum vibration resistance
in continuous operation.
The following table lists the major approvals:
