APPLICATION NOTES
1. OUTPUT DE-RATING
The operating ambient temperature range for VHK200W is -40 ~ +100°C, with the actual output power subject to the following
de-rating curves at free-air convection and at forced air conditions. To ensure long-term reliability, it is important to ensure proper
cooling at the worst operating conditions.
