Operating Temperature Range: -55 ~ 155
Power Derating Curve: Power can be adjusted according to the curve when ambient temperature exceeds 70 to 155.
Rated Voltage or Rated Current Calculation:
- For resistance values (1): E=(RP), where E is rated voltage (V), R is nominal resistance (), P is rated power (W). If calculated value exceeds max rated voltage, use max rated voltage.
- For jumper values (0): I=(P/R), where I is rated current (A), P is rated power (W), R is nominal resistance (). If calculated value exceeds max rated current, use max rated current.
