6 Burst test
The board has been tested against burst pulses, with good results. The tests have been
carried out using the following equipment and the procedures:
• Surge generator: Schaffner NSG 200 E 7 NSG 224 A
• Test types:
– SYM = symmetric with respect to earth pole (pulse applied between line and
neutral)
– ASYM = asymmetric (pulse applied between line and earth and between neutral
and earth)
• Output load 700 mA.
