What are the Differences Between IEC Power Supply Protection
2020年9月16日 · A common source of confusion is the difference between an IEC Class II power supply and an NEC Class 2 power supply. Class III Power Supplies In IEC Class III power supplies, the input voltage is not at a hazardous level, and thus the user does not need to be protected from the input voltage.
The Difference Between Input and Output Adapter Plugs - ASME
2022年3月23日 · In some single-phase ac power applications, both powers carrying conductors are "hot" and at opposite polarity relative to the ground potential. These conductors are often then labeled as Line 1 and Line 2. A Neutral conductor is not included if Line 1 and Line 2 conductors are used to deliver power from the wall socket to the power supply's input.
Design Protocols Via IEC 61558 for Power Supplies - ASME
2021年8月11日 · IEC 61558 is a series of standards maintained by the IEC Technical Committee (TC) 96 – “Transformers, Reactors, Power Supply Units and Combinations Thereof”. TC96 documentation explains that the committee is concerned with “transformers and power supply units intended to allow the application of protective measures against electric ...
Connecting Power Supplies for Increased Power Output - ASME
2021年9月15日 · Although the common method employed to increase the load power delivered from power supplies is to connect the outputs in parallel, another solution can be to connect the outputs of multiple power supplies in series. Power supply vendors such as CUI have technical staff who can help configure an acceptable solution to these and other power ...
The Basics of USB-C and USB Power Delivery - ASME
2021年3月30日 · This often creates confusion about the relationship between the concepts of Type-C, 3.1 Gen 2, and USB Power Delivery. It is important to note that while these concepts are related and complement one another, they are independent. A device or power supply can utilize a USB connector and not implement USB 3.1 Gen 2 or USB Power Delivery.
The Latest EU Efficiency Regulations and How We Got Here
2020年10月19日 · The most recent changes occurred in April of 2020 when the EU's Ecodesign 2019/1782 regulations governing external power supply efficiency went into effect. The new 2019/1782 standard is not the regulation many originally thought was going to be implemented and while the new efficiency limits are generally less stringent than what was ...

Explore How to Properly Select Dc-Dc Converters - ASME
2021年7月15日 · High power converters often include load voltage sense terminals to enable the converter to compensate for voltage drops in the conductors between the converter’s output and the converter’s load. Including remote on-off capability allows the designer to enable or disable the output voltage from the converter with an electronic signal.
How to Manage Regulations for Power Supplies - ASME
2022年4月5日 · Power conversion efficiency relates to the amount of wasted heat from the power supply that must be dissipated during the operation of the product. Product development teams often are interested in high power conversion efficiency to improve the system reliability and enable the design of smaller, lighter weight, and quieter products.
