   - *8 Only as standard mounting orientation (A). Refer to the “ Assembling and Installation Method”. If install other than standard mounting orientation (A), please fix the power supply for withstand the vibration and impact. 

- *2 Please contact us about dynamic load and input response. 

- *3  This is the value that measured on measuring board with capacitor of 22mF and 0.1mF at 150mm from output terminal. 

Measured by 20MHz oscilloscope or Ripple-Noise meter (Equivalent to KEISOKU-GIKEN: RM103). Please refer to the instruction manual 1.7. Ripple and ripple noise spec is change at Io=0 to 30% by burst operation. 

   - *9 When two or more units are operating it may not comply with the IEC61000-3-2. 

   - *10  If the overcurrent protection circuit operates continuously, the output voltage shut down. Refer to the instruction manual 1.3. 

- *4  In case of operating under 0C ambient temperature, the value is two times of specification at 0 to 30% load factor. 

   - *11  Under low DC input voltage below DC110V, the temperature derating -1C/V or the output power derating -1%/V are required. 

- *5  Drift is the change in DC output for an eight hour period after a half-hour warm-up at 25C, with the input voltage held constant at the rated input/output.

## Installation method 

- ¡ About DIN-Rail Attachment available with DIN EN60715 TH 35 (35×7.5mm or 35×15mm) (Top hat shaped DIN rail) 

- ¡ Below shows mounting orientation. 

If install other then standard mounting orientation (A), please fix the power supply for withstand the impact and vibration. 

- ¡ When you mount a power supply on a DIN rail, have the area marked A catch one side of the rail and push the unit to the direction of B. To remove the power supply from the rail, either push down the area marked C or insert a tool such as driver to the area marked D and pull the unit apart from the rail. When you couldn’t remove the unit easily, push down the area marked C while lightly pushing the unit to the direction of E. 

- ¡ Shown below the notes about installation clearance of a unit. 

## ¿ KHEA30F/60F/90F, KHNA30F/60F/90F 

- 1 Installation clearance at above and below the unit. Please have clearance of at least 25mm above and below the unit to avoid heat accumulation. 

- 2 Installation clearance at the side of the unit. 

- Please have clearance of at least 5mm side the unit to insulating the internal components. However, refer to right figure, if adjacent device of the unit (including power supply) is a heat source.

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.

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.
