Transient Protection (consult factory for availability)

The transient protector (option code T1) helps to prevent damage to the transmitter from transients induced on the bus/power wiring by lightening, welding, heavy electrical equipment, or switch gears. This option is installed at the factory for the Model 848L and is not intended for field installation. ASME B 16.5 (ANSI)/IEEE C62.41-1991

(IEEE 587), Location Categories A2, B3.

1 kV peak (10 x 1000 S Wave)

6 kV / 3 kA peak (1.2 x 50 S Wave 8 x 20 S Combination Wave)

6 kV / 0.5 kA peak (100 kHz Ring Wave)

4 kV peak EFT (5 x 50 nS Electrical Fast Transient)
