Ul1310 Class 2 Power Supply

Products of this type are covered by the standard for power units other than class 2 ul 1012.

Ul1310 class 2 power supply. 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. Class ii has more to do with power supplies that are likely to come into contact with a member of the public. If more than four branches are required multiple pisa modules can be connected to the power supply. 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.

Ul standard ul 1310 edition 7 standard for class 2 power units edition date. 2 only the load side of a dc power supply can meet the class 2 circuit requirem ents. 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.

Class 2 and class 3 transformers ul 5085 3. 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. 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. 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.

General requirements ul 5085 1 and the standard for low voltage transformers part 3. Power supplies that conform to class 2 are usually certified to ul1310. Using the sdp4 24 100 as an example the detailed application and fulfillment of the nec requirements for class 2 power sources is portrayed. The ul 1310 class 2 power units standard applies to power supplies within a limited output current and output voltage range.

March 09 2018 ansi approved. Our ul class 2 led power supplies meet the us power supply safety standards used to regulate low power sources. For small currents up to 2a pisa11 401 and pisa11 402 are suffici ent. The following technical note describes the requirements of a class 2 power supply.
