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
2MΩ
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 ;
