The ul 1310 class 2 power units standard applies to power supplies within a limited output current and output voltage range.
Ul1310 class 2 power supply.
General requirements ul 5085 1 and the standard for low voltage transformers part 3.
Class 2 and class 3 transformers ul 5085 3.
Power supplies that conform to class 2 are usually certified to ul1310.
Products of this type are covered by the standard for power units other than class 2 ul 1012.
Using the sdp4 24 100 as an example the detailed application and fulfillment of the nec requirements for class 2 power sources is portrayed.
2 only the load side of a dc power supply can meet the class 2 circuit requirem ents.
Ul class 1 vs ul class 2.
Class ii has more to do with power supplies that are likely to come into contact with a member of the public.
Ul standard ul 1310 edition 7 standard for class 2 power units edition date.
Nec class 2 pisa11 protection units can be used to cost effectively design four nec class 2 branch circuits using just one power supply and one pisa module.
Our ul class 2 led power supplies meet the us power supply safety standards used to regulate low power sources.
Compliance shall be determined by measurement and if required the assembly test in section 87.
Mean well do no offer a power supply that meets ul1310.
A flush device cover plate with integral power supply with one or more class 2 output low voltage connectors shall maintain a minimum of a 1 4 inch 6 35mm separation of branch circuit wiring and class 2 connections after installation.
The class 2 standard is specified in ul standard number ul1310 in order to receive the ul class 2 approval the power supply must have the output current not exceeding 8 a and the output voltage may not exceed 30 vdc.

60 watt led power supply 12v dc constant voltage output designed especially for led strip lights and module lighting projects ul cul certified with ul879 for signage applications ul1310 class 2 for commercial use compact cast aluminum housing with lead wires and thick gauge outer jacket weather proof ip67 rated for dry and damp locations.
For small currents up to 2a pisa11 401 and pisa11 402 are suffici ent.
Ul class 2 drivers comply with standard ul1310 meaning output is considered safe to contact and no major safety protection is required at the led luminaire level there is no risk of fire or electric shock.
The ul class 2 standard limits the output power to be less than 100w output current to 5a output voltage to 60vdc and leakage current to be less than 0 75ma.
These drivers operate using less than 60 volts in dry applications 30 volts in wet applications less than 5 amps and less than 100 watts.
