Application:
The 3KP series of high power transient voltage suppressors were designed to be used on the output of switching power supplies. These devices may be used to
replace crowbar circuits. Both the 5 and 10 percent voltage tolerances are referenced to the power supply output voltage level.
They are able to withstand high levels of peak current while allowing a circuit breaker to trip or a fuse blow before shorting. This will enable the user to reset the
breaker or replace the fuse and continue operation. For this type operation, it is recommended that a sufficient mounting surface be used for dissipating the heat
generated by the Transient Voltage Suppressor during the transient or over-voltage condition.
Transient Voltage Suppressors are Silicon PN Junction devices designed for absorption of high voltage transients associated with power disturbances, switching and
induced lighting effects. This series is available from 5.0 volts thru 220 volts.
