Operating Temperature

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

-65°C ~ 150°C (TJ)

P4SMA

Type

Zener

Applications

General Purpose

Power Line Protection

During fault, the only circuit breaker closest to the fault point should be tripped. The operating time of relay associated with protection of line should be as minimum as possible in order to prevent unnecessary tripping of circuit breakers associated with other healthy parts of power system.
