Ul1310 Class 2 Power Supply

If more than four branches are required multiple pisa modules can be connected to the power supply.

Ul1310 class 2 power supply.

For small currents up to 2a pisa11 401 and pisa11 402 are suffici ent. 2 only the load side of a dc power supply can meet the class 2 circuit requirem ents. Mean well do no offer a power supply that meets ul1310. 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.

Class 2 and class 3 transformers ul 5085 3. 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. 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. Our ul class 2 led power supplies meet the us power supply safety standards used to regulate low power sources.

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 ul 1310 class 2 power units standard applies to power supplies within a limited output current and output voltage range. Class ii has more to do with power supplies that are likely to come into contact with a member of the public. 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. Ul standard ul 1310 edition 7 standard for class 2 power units edition date. The following technical note describes the requirements of a class 2 power supply. March 09 2018 ansi approved.

Products without a rectifier may be covered by the standard for low voltage transformers part 1. 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. Compliance shall be determined by measurement and if required the assembly test in section 87. Ul class 1 vs ul class 2.

Power supplies that conform to class 2 are usually certified to ul1310.
