6.2.1
In-rush currents
These currents should be kept as low as possible. The root mean square (Irms)
< 0.2A. Reference Eqn 1 for (Irms)
Ir - In-rush current (A) Tr - In-rush time (sec)
Is - Switch current (A) Ts - Switch time (sec)
Tf - Operation time (sec)

Impulsions de courant
Toutes les impulsions de courant doivent être réduites au minimum. Valeur effective
(Irms) 0.2 A. Voir formule inférieure pour (Irms).
Ir = Impulsion de courant [A] Tr = Durée de l’impulsion de courant [s]
Is = Courant de commutation [A] Ts = Durée de commutation [s]
Tf = Temps d’activation [s]
FRE
Stromstöße
Alle Stromstöße sollten so klein wie möglich gehalten werden. Effektivwert (Irms) 0.2
A. Siehe untere Formel für (Irms).
Ir = Stromstoß [A] Tr = Zeitdauer des Stromstoßes [s]
Is = Schaltstrom [A] Ts = Schaltdauer [s]
Tf = Aktivierungszeit [s]

Impulsos de corriente
Todos los impulsos de corriente deberán mantenerse a un valor lo más bajo posible.
Valor eficaz (Irms) 0.2 A. Ver abajo la fórmula para (Irms).
Ir = Impulso de corriente [A] Tr = Duración del impulso de corriente [s]
Is = Corriente de conexión [A] Ts = Duración de conexión [s]
Tf = Tiempo de activación [s]
