Electrical Durability (in Millions of Operating Cycles) Conforming to IEC 60947-5-1
control of resistive loads and of solid state loads isolated by optocoupler, l/R ≤ 1 ms.
switching electromagnets, L/R ≤ 2 x (Ue x Ie) in ms, Ue: rated operational voltage, Ie: rated operational current (with a protective diode on the load, DC12 curves must be used with a coefficient of 0.9 applied to the number in millions of operating cycles)
control of resistive loads and of solid state loads isolated by optocoupler, cos ϕ ≥ 0.9.
control of small electromagnetic loads ≤ 72 VA, make: cos ϕ = 0.3, break: cos ϕ = 0.3.
control of electromagnetic loads > 72 VA, make: cos ϕ = 0.7, break: cos ϕ = 0.4.
