Do you want to learn about the updated 62368 safety standard, compare the differences between ITE and medical power supplies, or find the perfect power solution? Our expert blog provides professional industry insights.
In-depth analysis of what an ITE power supply covers, including its core definition, common applications such as routers, servers, and switches, and the main industry standards, enabling you to build the basic knowledge of the product quickly.
A common point of confusion when purchasing: what is the difference between an ITE power supply (IEC 62368) and a medical power supply (IEC 60601)? This article compares the safety isolation levels, leakage current requirements, and application to prevent choosing the wrong one, which can lead to system certification failure.
With the 60950 standard completely replaced by 62368-1, what happens to power supply compliance? This article breaks it down for you: the updated safety requirements, energy efficiency standards (Level VI), and certification lists for exporting to European and American markets.
When you face 12V, 24V, 48V, and many other voltage specifications, how do you choose a stable ITE power adapter for your equipment? This guide provides selection advice from current derating and thermal design to DC plug type selection.
Our ITE power supply design is based on the IEC 62368-1 safety standard system and universal use for IT and industrial equipment. The judge, if it matches your equipment, still needs to combine with the whole structure, the electrical isolation requirement(like creepage and clearance), and finally the certification path. Generally, in the evaluation stage, we judge direct use or the need for an adjustment solution according to your system structure.
In the actual use of an ITE power supply, you cannot just focus on the rated voltage and observe the actual working environment inside the equipment. For example, in routers, switches, or industrial control equipment, the temperature inside the computer case is often higher than outside, specifically in limited space or situations involving poor airflow. So many power supplies will allow for temperature and load margins and will not run in the fully loaded state for a long time. In the 40℃ to 50℃ or higher environment, we suggest derating to ensure reliability for a long time.
Ripple, noise, and EMI are not directly reflected in the paper parameters and are actually observed during system debugging or EMC testing. In some network equipment, if using the same power supply, different PCB layout or filtering design results in different outcomes. EMI is not solved depending only on the power supply; grounding method, cable routing, and shielding design all affect the final result. So we usually only focus on power supply data, and the complete unit conducts an EMC test together.
24/7 continuous operation is a common type in network equipment and servers. Most ITE power supplies are designed for this solution. The actual effect on lifespan is not just that it is left on all the time, but depends on operating conditions such as temperature, ventilation, and long-term full-load operation.
Our Quankang ITE power supply units come standard with the usual suspects: Over-voltage (OVP), Over-current (OCP), and Short-circuit (SCP) protection. Some models also feature Over-temperature protection (OTP). However, don’t just assume these are “set and forget.” Depending on the harshness of your specific ITE power supply operating environment, we often need to tweak these trip points to ensure they trigger only when they actually should, without causing false shutdowns.
Stability isn’t a happy accident; it’s a managed process. For our industrial clients, we control risks through a very strict framework: we handle active Component Lifecycle Management for every ITE power supply to track PCN/EOL alerts, enforce a strict BOM locking strategy, and perform rigid batch consistency controls. This is the only way to guarantee that the Quankang ITE power supply we ship today will still be supportable and reliable years down the road.
Before ITE power supply customization, you need to provide basic information to us:
1)Input voltage range (e.g., 100-240V).
2)Output voltage and current.
3)Application (e.g., CCTV, routers, industrial equipment).
4)Operating environmental conditions.
Our engineering team chose a standard model or a full custom design stage based on this information.
Our ITE power supply conducts EMC pre-compliance testing in the design stage so that meet the requirements of the common market. One needs to notice that the final EMC performance depends on the whole machine system design, such as structural layout, grounding method, and wiring harness routing. ITE power supply universal assures single compliance, the system level compliance need combine with the whole machine verified.
MTBF is an index for judging reliability reference by power supply manufacturers, which is mainly based on component data and test models. Our ITE power supplies’ MTBF is generally 100,000 hours at full load at 25℃ ambient, calculated per MIL-HDBK-217. But the actual lifespan is different because the same power supply has different performance under different temperature, load, and heat dissipation conditions.
Our delivery time often depends on the project solution and is not fixed. A standard model custom service is usually short. For instance, modifications to electrical parameters, structural adjustments, or changes in certification requirements can extend the timeline. In addition, delivery times are also affected by component availability, order volumes, and the production line schedule at the time. A relatively accurate timeframe can only be provided once the plan has been confirmed.
Our standard MOQ is 1,000 items to ensure production efficiency and cost structure. For some solutions, assessments are based on electrical design complexity, structural adjustments, and certification requirements, and are not entirely fixed. After the project evaluation, we provide a detailed MOQ plan for you.
In the sample stage, prioritize scheduling after confirming the specification, use for electricity verification and system test, and universal needs about 15 days.
In the bulk production stage, the cycle will be affected by material preparation and scheduling, especially if the ITE power supply design involves customization. So the whole cycle needs to be evaluated based on detail solution and not a fixed time. We will offer a close production ITE power supply delivery plan.
