Insulation
Separated by reinforced insulation or double
insulation from hazardous voltage.
If the product is used as a UL-approved product, the external power supply must be
provided from a limited voltage/current circuit
*1
or class 2 power supply
*2
.
If the product is used as a CE-complied product, the external power supply must be
provided from a SELV and limited-energy circuit*3 separated by reinforced insulation or
double insulation from hazardous voltage.
*1
A limited voltage/current circuit is a UL508-approved isolated power supply which is limited to 30V AC or 42.4V peak
in output voltage and to 8A in output current.
*2
A class 2 power supply is a UL1310-approved power supply which is tested and proved by UL that its output voltage
is 30V DC max. and its output current is 8A max.
*3
A SELV and limited-energy circuit is defined in the EN61010-2-201. It is limited to 30V ACr.m.s., 42.4V peak, or 60V
DC in output voltage and limited to 6.25A (24V DC), 8.3A (12V DC), 20A (5V DC) in output current, in normal and
single-fault condition.
