Additional Information
- Operating Temperature Range: -55 to +170.
- Rated Current Calculation: I = sqrt(P / R). If calculated value exceeds maximum working current, the maximum working current shall be regarded as rated current.
- Power Derating: Maximum load power should be reduced when operating in ambient temperatures above 70 C, as per derating curve.
