Safety regulation
Conform to IEC60950-1 standards
Acoustic noise
≤ 60db (A) (When the ambient temperature is lower than25°C)
Insulation resistance
At temperature of 15°C ~ 35°C and relative humidity not bigger than 90%RH,
apply a test voltage of 500Vdc. The insulation resistances between AC circuit
and earth, DC circuit and earth, and AC and DC circuits are all not less than
2
MΩ
Insulation strength
(Remove the SPD, controller and rectifiers from the system before the test.)
AC loop to DC loop can withstand 50Hz. AC to DC circuits: 3,000Vac; or
4,242Vdc for one minute, leak curren
≤10mA , without puncturing and electric
arcing;
AC circuit to earth: 50Hz, 2,500Vac; or 3,535Vdc for one minute, leak
curren
≤10mA , without puncturing and electric arcing ;
DC circuit to earth: 50Hz, 1,000Vac; or 1,414Vdc for one minute, leak
curren
≤10mA , without puncturing and electric arcing ;
Auxiliary circuit without connecting to the main circuit directly: 50Hz,500Vac; or
707Vdc for one minute, leak curren
≤10mA , without puncturing and electric
arcing ;
