Introduction
|
|
|
The
u201 filter Range has been specifically designed to overcome EMC
problems inherently caused by switched
mode power supplies, in applications especially where size constraints
and low earth leakage are an issue.
This new range of micro size filters have high attenuation factors
and high current capabilities without having a large profile. Switched
mode power supplies electronically switch high voltages and currents
to improve efficiency and reduce losses in power conversion. This
switching generates high levels of Radio Frequency Interference
(RFI) and high energy surges which can disturb or damage other electronics
circuits.
The u201 series is a two stage design in a 2 line format, with excellent
suppression characteristics particularly
at 10K - 200KHz where power supplies tend not to perform and require
effective attenuation, the filter will also effectivly reduce harmonic
distortion. They also have very low earth leakage which give the
added benefit of being able to be used in medical devices and applications.
The filter components are housed in compact chassis mounted, aluminium
enclosures that allows side or base
mounting, it is then encapsulated in a polyurethane potting compound
to give excellent protection against shock and vibration. These
combinations give a total range of over 20 filter applications.

Regulations
|
|
| From
the 1st of January 1996 all electrical/electronic apparatus - with
few exceptions - sold or taken into service within the European Community
must comply with the essential requirements of the EMC directive 89/336/EEC.
Failure to do so is a criminal offence in the U.K. |

Standards
|
|
The
u201 range of filters are built in accordance with the relevant BS,
VDE, UL, CE & CSA safety standards.
All EMC Solutions filters & power supplies are designed to meet
the latest requirements for Health and Safety, Particularly EN 133200
The u201 range is specifically designed to assist AC input - DC Output
switched mode power supplies to meet European Emission standards.
eg. EN55011, EN55014, EN55022, EN50081-2 and EN50081-1. |
