What is a UL Class 2 power supply?

A class 2 is a standard described in UL1310 as a power supply that (1) does not have an output current of more than 8A, (2) does not have an output voltage greater than 30VDC, and it is subject to standards that require certification via UL testing.

Full answer is here. Also asked, what is a Class 2 power supply?

In general, a Class 2 circuit (operating at 24V with a power supply durably marked "Class 2" and not exceeding 100VA) is the type most commonly used. The NEC defines a Class 2 circuit as that portion of the wiring system between the load side of a Class 2 power source and the connected equipment.

Beside above, what is UL class2? The UL Class 2 Power Units standards apply to power supplies within a limited output current and output voltage range. The Class 2 standard is specified in UL Standard Number UL1310. In order to receive the UL Class 2 approval, the power supplies must pass UL testing as follows: The output current does not exceed 8 A.

Correspondingly, what is UL power supply?

UL relates to. devices that are connected to mains power, and is mainly designed to protect. equipment and facilities. UL testing involves making sure that power. connections are made propely, and that the correct materials are being used.

What is the difference between Class 1 and Class 2 wiring?

Class 1 wiring is actually required to exceed standards for power and lighting wiring. It must sit in metal or non-metallic raceway or be metal-sheathed wiring as compared to jacketed cable such as type NM. Class 3 wiring is functionally similar to Class 2 wiring, but with higher voltage and power limitations.
