When the USB Type-C specification was originally published in 2015, it promised to support greater speed, more power, and more convenience than historical USB technologies. A little over a year later, the USB Type-C connection is gaining greater adoption, and it is changing the way manufacturers can utilize the USB connection.

Globtek applies for IEC 60601-1 medical Safety Approvals and EMC approvals on their standard power supply products. The medical approvals for Safety and EMC are required to exist in separate CB reports. There is often confusion regarding the differences between IEC 60601-1 ed 3, and IEC 60601-1 ed 3.1.

With less than a year left before the US Department of Energy's Level VI energy efficiency regulation becomes mandatory, system-level engineers and specifiers are now focused on testing and qualifying external power supplies from different vendors that meet the upcoming efficiency and no-load input power require- ments. With GlobTek's newly released Level VI compliant product line, these tasks can be simplified and expedited allowing manufacturers shorter time to market. GlobTek will continue to invest in research and development to push the boundaries of power supply efficiency and no-load input power consumption to meet and exceed current and future energy efficiency standards.

IEC62368-1 and UL1310 are product safety standards which aim to keep humans safe by lowering the the possibility of hazardous occurances. Both standards agree that limiting the output power of power supplies connected to mains results in a reduced risk of fire, especially during an overload condition. While the two share similar ideas, the requirements and definitions differ slightly.

During EMC testing at the compliance lab, complex customer systems are exposed to several different forms of electromagnetic energy, both wire conducted and thru the air. The most prevalent problem we have noted during the immunity test suite of the customer system is EFT failure. Following the measures in this paper may i provide for a 2X to 3X increase in EFT immunity performance of the customer system.

When using a non-standard output cable with a power supply, it is useful to be able to understand the expected voltage of the new required cable for a custom application. By entering the wire gauge, cable length, output voltage and output current, the expected output regulation effect may be determined.

Power over Ethernet (PoE) as defined in the IEEE802.3 standard, has developed over the last 16 years into a mature technology capable of supplying up to 100W of remote DC power to Ethernet Appliances in locations where it is not practical to provide AC mains power, and an isolated AC/DC power supply for the Ethernet Appliance. New technological advances by Globtek now allow high Energy Efficiency performance from PoE networks, and compliance with the new US Department of Energy (DoE) Efficiency Level VI External Power

When the patient must be protected from electrical contact with the medical device, the usage environment may be classified as BF or CF per IEC 60601-1. With a floating output application, there are two ways to attain the floating status in the power distribution

The International Electrotechnical Commission (IEC) is the leading global organization that prepares and publishes International Standards for all electrical, electronic and related technologies. Both Safety and Electromagnetic compliance standards are produced by the IEC. This article discusses the difference between 60601-1-2 4th Edition vs. EN 60601-1-2:2015 vs IEC 60601-1-2:2014-02

The IEC 62368-1 draft standard defines a new set of safety requirements for certain types of electronic equipment. This paper outlines the scope and characteristics of IEC 62368-1 and examines the place of the new standard in the market. It then analyzes design concerns that will pose certification challenges once the new standard is enforced and explores s aspects of compliance that can be addressed now. Finally, it outlines a path manufacturers and systems integrators can take toward eventual certification under the new standard.

IEC 62368-1:2014 recognizes that requiring all existing certified components to transition to the new standard would impose a tremendous burden on manufacturers and certification bodies alike, and so in clause 4.1.1 states that, "Components and subassemblies that comply with IEC 60950-1 or IEC 60065 are acceptable as part of equipment covered by this standard without further evaluation other than to give consideration to the appropriate use of the component or sub-assembly in the end product."

The 60601-1 collateral standard for medical EMC is 60601-1-2, presently the 3rd edition of the standard is in force. However in December 2018, newly certified (or recertified) medical devices will be required to meet the more rigorous requirements from the 4th edition. Therefore, most medical equipment manufacturers are opting for doing EMC evaluations to the 4th edition at the current time.

Power supplies must comply with safety standards to protect equipment end-users and operators.

Not every thermal challenge involves hot or wet environments, as we recently found out when GlobTek provided a power supply solution to serve an RFID application.

When you consider that a power supply is essential to electronics, it is amazing that so many designers wait until the end of the design process to design-in their power source. This is especially amazing today given that so much can be gained in system performance and efficiency, regardless the core technology or end product, by properly integrating the power supply into it.

With less than a year left before the US Department of Energy's Level VI energy efficiency regulation becomes mandatory, system-level engineers and specifiers are now focused on testing and qualifying external power supplies from different vendors that meet the upcoming efficiency and no-load input power require- ments.
