Do not touch any SMD components on the unit. Be especially careful when handling. - ¡ If using a metal chassis, keep proper insulation between the component and metal chassis, use the spacer of 8mm or more between bottom of power supply and metal chassis (except -N model). - If d1 and/or d2 are less than the value mentioned in right figure, insert an insulating sheet with reinforced insulation between the power supply unit and metal chassis (except -N model). - The following distance is not satisfactory for cooling condition. Please refer to “Derating” and Instruction Manual 4 for cooling method. - ¡ There is a possibility that it is not possible to cool enough when the power supply is used by the sealing up space as showing in right figure. - Please use it after confirming the temperature of points 1 of Instraction Manual 4. **==> picture [215 x 230] intentionally omitted <==** **----- Start of picture text -----**<br> d2<br>CN1<br>d1＝8mm min<br>d2<br>CN1<br>d2<br>d2<br>d2＝5mm min<br>d2<br>Case<br>Power supply<br>**----- End of picture text -----**<br> - ¡ Standard model can be mounted in the mounting position shown in the figure below. **==> picture [448 x 106] intentionally omitted <==** **----- Start of picture text -----**<br> (A) (B) (C) (D) (E) (F)<br>CN1<br>CN1 CN1<br>CN1<br>CN1<br>Standard position<br>CN1<br>**----- End of picture text -----**<br> - ¡ Option-N model can be mounted in the mounting position shown in the figure below.The installation of (F) possible only forced air cooling. **==> picture [453 x 102] intentionally omitted <==** **----- Start of picture text -----**<br> (A) (B) (C) (D) (E) (F)<br>CN1<br>CN1 CN1<br>CN1<br>Standard position CN1<br>CN1<br>**----- End of picture text -----**<br> **TECS-6** www.cosel.co.jp/en/ June 10, 2024 ## **TECS-series** ## **Mounting Area** - ¡ The mounting screw should be M3.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
