A limited power source (LPS), as defined in IEC-60950-1, is a secondary circuit with an open circuit output voltage, VOC, not exceeding the SELV circuit limits of 42.4 VPEAK or 60 VDC.Nov 8, 2019
What is LPS on AMP?
For example, LPF (sometimes referred to as LP) refers to Low Pass Frequencies and is used for subwoofers designed to play only the lowest notes.
What is a Class 2 or LPS power supply?
Limited Power Source (LPS) power supply which relates to the VA rating of the output being limited. A class 2 power supply has a maximum output VA rating of 100VA if the power factor is less than 0.9 or 100W if the power factor is above 0.9.
What is a Class 2 power supply?
A class 2 power supply has a maximum output VA rating of 100VA if the power factor is less than 0.9 or 100W if the power factor is above 0.9. In addition, the maximum allowable output current under any condition is 8A and the maximum output voltage under any condition is 30VDC.
How do I know if I have a Class 2 power supply?
IEC protection Class II power supplies will have a two-wire power cord as opposed to a three-wire power cord with Safety Earth connection. Products designed with Class II insulation often are labeled as “Class II” or “double insulated” or will have the concentric square symbol on the safety label.Sep 12, 2017
What is a Class 2 power circuit?
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. Due to its power limitations, a Class 2 circuit is considered safe from a fire initiation standpoint and provides acceptable protection from electrical shock.
What does a class 2 mean?
A Class II or double insulated electrical appliance is one which has been designed in such a way that it does not require a safety connection to electrical earth (ground).

What are the three categories of power source?
There are three subsets of regulated power supplies: linear, switched, and battery-based.
