Information Technology Equipment

Applicable standards for information technology equipment

Since there are many target devices, we will extract some examples below. J60950, the technical standard of PSE of Japan that draws on the flow of IEC, states that the following devices are applicable.

• Phone
• FAX
• Modem
• Copier
• Router
• Office supply
• Recorder
• Computer
• Public information terminal, etc.

When discussing the broad range of applicable standards for various devices, it's more than just specific listed devices that are considered. Devices can also be classified as information equipment based on the evaluation of certification bodies, making the standards applicable.

AC adapters used in countries participating in the CB Scheme must conform to the IEC60950 technical standards and each country's unique safety standards. Given that IEC60950 is commonly adopted across various countries, we find it helpful to highlight the uniformity in these technical standards internationally and, at this moment, introduce an overview of these commonalities.

Comparative example of "Technical standard" of legal safety standard required for selling information technology equipment in the United States and Europe

Even in countries that have yet to ratify the CB scheme, many countries like Taiwan and China have technical standards very close to IEC 60950. UNIFIVE offers a wide range of lineups, and IEC 60950 has been acquired for items corresponding to this information technology equipment. Although there are differences depending on the series, we have acquired safety standards of 60950 standards for each country using the IEC 60950 acquired, so you can find an AC adapter that can do so to your expectations. 

Examples of information technology equipment

Case 1:  AC adapter for Wifi rooter importer.

Previously, from customers who have imported WiFi access points from abroad:

"Because the included AC adapter is an overseas standard, the plug's shape is also different. We want a highly reliable AC adapter that has acquired equivalent standards."

Of course, we are proposing an AC adapter that PSE and IEC 60950 could obtain in selecting the target, but we confirmed the following contents and evaluated it.

-      What kind of things are good for DC plug

-      Submission of reliability data. MTBF, lifetime data, open short test, etc.

The evaluation was successfully approved, and we delivered mass-produced goods by the date of sale definitely and in time for shipment.

Case 2:  Development for the carrier of a major telecom

Create custom power supplies for routers for certain carriers in Japan. As mentioned above, customers previously requested that we create custom AC adapters for major domestic telecommunications carriers. Although the product is for domestic use, it must satisfy IEC 60950 as an incidental reliability condition. We had to make custom adjustments to fulfill the carrier's reliability criteria and the customer's power supply adoption criteria to be manufactured. 

As mentioned in Case 1, please let us know about the hearing of requests related to the power supply of such a case and initial confirmation concerning the customer's application. At our initial stage, we are proposing a solution in which our experienced power consultant takes the initiative to hear about the information on the power supply adoption standard that is necessary at that point, and we are satisfied.

Among the requests, there were items requiring detailed discussion and adjustment of how to respond to customers, such as provision on heat generation of products, adjustment of conduction noise, etc. However, after successful development and mass production, we delivered on time. In this equipment, the customer paid for expenses related to the acquisition of custom and safety standards, such as the acquisition cost of the PSE and IEC 60950, circuit development cost, and jig preparation fee.

Case 3:  Development for Gateway products.

We received an inquiry from a Wireless device manufacturer that produces an IoM gateway(*IoM is a registered trademark of IDY corporation).

They were looking for an AC adapter working in -20 to 60℃ conditions. But It was pretty hard because of on-market AC adapters.

The operating temperature range is 0℃ to 40℃ in general.

We found three key points of the usage environment of these gateway devices from an interview with the client. 

1:  Once this getaway is set in position, the device will never move from the same place.

2: The gateway would be installed in a sunny place, such as the roof space or near the window. Therefore, the gateway would be in an environment with drastic temperature changes.

3: Gateways would be installed in shopping malls, high-speed trains, households, factories, etc. 

According to the interview, we modified the AC adapter to have a DC slightly higher than the customer's DC of actual use so it could operate at -20℃ to 60℃.

The client was satisfied with our modification proposal.

This client could sell to the national high-speed train, and we appreciate it. We have a variety of comprehensive operating temperature range models, the SU series.
