Charger
This AC charger has been designed to meet the requirements of the EMC Directive 89/336/EEC.
Compliance was demonstrated by meeting the test limits of the following standards:
Emissions
EN55022, radiated and conducted Class B.
Immunity
Test methods, limits and performance achieved were:
a) EN61000-4-2 (1995) Electrostatic Discharge : 4kV air, 4kV contact, Performance B.
b) EN61000-4-3 (1997) Electromagnetic Field, 3V/m, 80% AM at 1kHz, Performance A.

100ms, Performance C.
d) EN61000-4-4 (1995) Fast Transient, 1kV peak (AC line), Performance B
e) EN61000-4-5 (1995) Surge, 1kV (line to line), 2kV (line to ground), Performance B.
f) EN61000-4-6 (1996) Conducted RF, 3V, 80% AM at 1kHz (AC line only; DC Output
connection <3m, therefore not tested), Performance A.
Performance Definitions
The definitions of performance criteria are:
Performance criterion A: 'During test normal performance within the specification limits.'
Performance criterion B: 'During test, temporary degradation, or loss of function or
performance which is self-recovering'.
Performance criterion C: 'During test, temporary degradation, or loss of function or
performance which requires operator intervention or system reset occurs.'
Class B
9. EMC
