What is the difference between a switching and linear power supply?
Linear power supplies deliver DC by passing the primary AC voltage through a transformer and then filtering it to remove the AC component. Switching power supplies feature higher efficiencies, lighter weight, longer hold up times, and the ability to handle wider input voltage ranges.

What is a LPS power supply?
What is an LPS Rated Power Supply? An LPS rated power supply is designed for safety reasons to conform to a maximum permitted output voltage, output current and output power rating. Regulatory agencies have created many designators for power supplies which conform to different sets of specifications.
Why is DC current not used in homes?
Direct current is not used at home because for the same value of the voltage, DC is more lethal than AC since direct current does not go through zero. Electrolytic corrosion is more an issue with direct current.
What is lab power supply for?
When you want to test an electrical circuit, or components, they often need to be powered by a voltage. For example, you could use a mains adapter, but a lab power supply is more suitable. A lab power supply shows the current and voltage, so you can see what is happening. The current and voltage can also be set.
What is LPS output?
A Limited Power Source (LPS) as defined in IEC 62368-1 and IEC 60950, is a secondary circuit with an open circuit output voltage, UOC, not exceeding the SELV circuit limits of 42.4 VPEAK or 60 VDC. The output power must not exceed 100W.
What is a Class 2 or LPS power supply?
Limited Power Source
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.

How good is the Astron rs-35a?
Having owned the Astron RS-35A (from DX Engineering) for more than 4 years, it is quiet and having installed a Volt Meter in the Shack displaying output of the Astron (35A Peak), its output has been always stable and constant even with my HF ICOM 718 and 2 meter ICOM V8000 operating.
Why choose Astron DC power supplies?
When you are in need of reliable DC power supply, look no further than Astron Power Supplies. Astron DC power supplies are made of heavy-duty, high-quality materials. Astron has your power requirements covered with a wide variety of voltage and amperage outputs and case styles with and without meters.
How many amps does the rs-35a carry?
The RS-35A has a continuous duty rating of 25 Amps according to the catalog, or 27 amps according to the data plate on the bottom of my unit. Either way, it’s enough to comfortably keep a typical 100W transceiver going indefinitely, with capacity to spare.
What do the Astron model numbers mean?
A few words about ratings: The Astron model numbers include their peak current rating. For example, the RS-35A can deliver up to 35 amps at 13.8VDC. However, this is an “ICS” rating, for intermittent duty only.
