UL 1310 UL Standard for Safety for Class 2 Power Units

These requirements cover indoor and outdoor use Class 2 power supplies and battery chargers.
These units uiie an isolating transformer and may incorporate components to provide an altermating- or direct-current output. Each output provides Class 2 power levels in accordance with the National Electrical Codo, NFPA 70. Maximum output voltogo docs not cxo00d 42.4 V poak for altamating ourront, 60 V for continuous direct current. These products are intended primarily to provide power to low voltage, electrically operated devices. These requirements apply to:
a) Portable and semipermanent mounted direct plug-in units provided with 15 A blade configurations for use on nominal 120 or 240 V alternating current branch circuits with a maximum potential of 150 V to ground;
b) Cord- and plug-connected units provided with a 15 or 20 A attachment plug configuration for use on nominal 120 or 240 V altemating current branch circuits with a maximum potential of 150 V to ground
c) Unite pormanently connected to the input supply for u80 on nominal 600 V or le88 alternating or direct current branch circuit. Direct plug-in and cord-connected units may also be provided with an integral cigarette lighter connector assembly, or a direct current input jack for being powered from a vehicle battery adapter or from a data port associated with information technology equipment. These units utilize an isolating transformer and may incorporate components to provide an altermating- or direct-current output.

Each output provides Class 2 power levels in accordance with the National Elecrical Code, NFPA 70. Maximum output voltage does not exceed 42.4 V peak for alternating current, 60 V for continuous direct current. These products are intended primarily to provide power to low voltage, electrically operated devices.
