Introduction
|
|
The
u700 filter has been specifically designed to overcome EMC problems
inherently caused by the DC drives in motor drive applications especially
where size constraints are an issue.
This new range of micro size filters have high attenuation factors
and high current capabilities without having a largeprofile. Motor
drives electronically switch high voltages and currents to improve
efficiency and reduce acoustic noise in the motor. This switching
generates high levels of Radio Frequency interference (RFI) and
high energy surges which can disturb or damage other electronics
circuits.
The u700 series is a two stage design in 2, 3 or 4 line formats,
with output line inductors to suppress dI/dT switching currents
that are harmfull to capacitors that are present on the supply.
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 30 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
u700 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 u700 range is specifically designed to assist AC input - DC Output
industrial frequency converters to meet European Emission standards.
eg. EN55011, EN55014, EN55022, EN50081-2 and EN50081-1. |
