review<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Start_with_the_operating_point_not_a_derating_percentage\"><\/span>Start with the operating point, not a derating percentage<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Before opening a graph, write down the operating point that the power supply must survive. That means the complete model suffix, continuous load, input condition, local air temperature at the location defined by the manufacturer, installation altitude, mounting orientation, enclosure layout, clearances, adjacent heat sources, and airflow. A curve can only answer the question represented by those conditions. <\/p>\n<p>Temperature and altitude are not two labels for the same problem. Temperature evidence describes how the unit&#39;s thermal headroom changes as the surrounding air becomes warmer. Altitude evidence addresses operation as air density and electrical-clearance conditions change with elevation. A manufacturer may present them in separate figures, attach different assumptions, or require a special rule when both apply. <\/p>\n<p>This is why a generic statement such as \u201creduce the load at high temperature\u201d is not enough for procurement. The buyer needs an allowed continuous output tied to the exact model, the actual environment, and a controlled source revision.  <\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_should_you_read_a_temperature_derating_curve\"><\/span>How should you read a temperature derating curve?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>First check what the horizontal axis actually measures. \u201cAmbient\u201d may be defined at a particular point near the enclosure rather than at a room thermostat or cabinet door. The primary manufacturer document retained with this package is useful because it defines a local ambient reference and presents its model&#39;s temperature behavior together with installation notes. It is method evidence only; none of that model&#39;s numerical values apply to a WEHO product.   <\/p>\n<p>Next check the output axis. It might show current, power, or a normalized load. Keep the manufacturer&#39;s unit through the reading step. Converting current to power, or the reverse, requires the ordered output variant and a valid conversion basis. Do not silently turn one kind of curve into another. <\/p>\n<p>Finally read the notes around the graph. Mounting direction, cooling method, clearance, nearby heat sources, input range, and permitted interpolation can change the meaning of a plotted point. A line should not be extended beyond the documented region simply because it appears straight. If the required point falls outside the figure or cannot be read with the required precision, the correct worksheet entry is \u201cengineering confirmation required.\u201d  <\/p>\n<p>A thermal shutdown or over-temperature protection statement does not fill this gap. Protection describes a response to an abnormal condition; a temperature derating curve defines an intended continuous operating region. They answer different design questions. <\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_is_altitude_derating_different\"><\/span>How is altitude derating different?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Altitude deserves its own row in the review. The site elevation must be compared with an altitude figure or a written model-specific limit, along with any stated ambient, mounting, or input assumptions. Do not infer the altitude result from a temperature curve, even when both ultimately restrict continuous load. <\/p>\n<p>The retained third-party primary document demonstrates the distinction: it presents output-versus-altitude information separately from output-versus-temperature information and also discusses installation conditions. That structure is a useful reading example. Its breakpoints, slopes, clearances, and operating values belong only to the named third-party model and are deliberately omitted from the WEHO calculation.  <\/p>\n<p>If the WEHO public page does not provide an altitude curve for the complete model, mark the altitude result unknown. A working-temperature range, product-family resemblance, or protection entry cannot be used to manufacture an altitude allowance.   <\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_do_you_combine_temperature_altitude_and_installation_limits\"><\/span>How do you combine temperature, altitude, and installation limits?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Build the answer one constraint at a time. For each applicable condition, record the source, revision, assumptions, point read, allowed continuous load, and uncertainty. When those values are independent ceilings for the same operating point, the conservative result is the lowest verified ceiling. <\/p>\n<p><strong>Allowed continuous load = minimum of the verified temperature, altitude, mounting, input, and airflow ceilings.<\/strong> <\/p>\n<p>That expression is a comparison rule, not permission to invent a missing input. It also does not supersede a manufacturer instruction that explicitly combines conditions another way. If the exact model documentation says to multiply factors, use that instruction and retain the calculation. If it gives no simultaneous-condition rule, ask for one rather than multiplying generic factors by habit.  <\/p>\n<table>\n<thead>\n<tr>\n<th>Review item<\/th>\n<th>Evidence to record<\/th>\n<th>Decision<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Exact model<\/td>\n<td>Full suffix and output variant<\/td>\n<td>Stop if only the family is known <\/td>\n<\/tr>\n<tr>\n<td>Temperature<\/td>\n<td>Defined ambient point and model curve<\/td>\n<td>Record the allowed load or mark unknown <\/td>\n<\/tr>\n<tr>\n<td>Altitude<\/td>\n<td>Site condition and model curve<\/td>\n<td>Record the allowed load or mark unknown <\/td>\n<\/tr>\n<tr>\n<td>Installation<\/td>\n<td>Orientation, clearance, enclosure, airflow, input<\/td>\n<td>Confirm the real layout matches the curve assumptions <\/td>\n<\/tr>\n<tr>\n<td>Simultaneous limits<\/td>\n<td>Manufacturer rule or independent ceilings<\/td>\n<td>Use the stated rule; otherwise use only the lowest verified ceiling and escalate unknown interactions <\/td>\n<\/tr>\n<tr>\n<td>Approval<\/td>\n<td>Source revision, reviewer, date, accepted load<\/td>\n<td>Freeze the result with the project record <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><img decoding=\"async\" src=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho-power-supply-derating-guide-diagram-de87a75a52.png?quality=85&strip=all\" alt=\"Power Supply Derating Guide for Temperature and Altitude  title=\" Power Supply Derating Guide for Temperature and Altitude title=\"\"><\/p>\n<p><em>Deterministic decision flow derived from verified model-specific documentation; not a WEHO performance curve.<\/em>   <\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_does_a_defensible_worksheet_look_like_when_data_are_incomplete\"><\/span>What does a defensible worksheet look like when data are incomplete?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Imagine that the exact temperature curve provides one permissible load, the exact altitude curve provides another, and the mounting note provides a third. Enter all three as separate ceilings and choose the lowest only after confirming that they describe the same model and operating point. If one curve is missing, do not replace it with a guessed value; the worksheet remains open.  <\/p>\n<p>This approach may feel slower than applying a familiar percentage, but it is faster than unwinding an unsupported approval later. It also makes an engineering question easy to answer: \u201cWhich specific evidence would change this result?\u201d The unknown row identifies the document or written confirmation that is still required. <\/p>\n<p>Keep load margin and transient behavior as separate checks. Environmental derating determines the permissible continuous ceiling. Startup demand, short-duration peaks, coordination, and system margin determine whether the application fits below that ceiling. Blending those steps into one undocumented factor makes the review difficult to reproduce.  <\/p>\n<h2><span class=\"ez-toc-section\" id=\"Which_WEHO_products_belong_in_this_review\"><\/span>Which WEHO products belong in this review?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The selected products represent two DIN-rail formats and an enclosed PFC family.
