The solid-state relay is designed for zero-point switching in single-phase applications, providing efficient control for electrical circuits.
No, the control supply voltage for this relay is DC only, with a rated value of 30 V and an operating range of 15 to 24 V.
The maximum operating current for the 3RF2090-1AA02 is 90 A when used in AC-1 applications at 400 V.
The relay can operate within an ambient temperature range of -25 to +60 °C and can be stored in temperatures ranging from -55 to +80 °C.
The relay is designed for screw fixing and can be mounted side-by-side with other units.
The insulation voltage rated value for this relay is 600 V.
The minimum operating current for the relay is 500 mA.
The dimensions of the relay are 45 mm in width, 58 mm in height, and 48 mm in depth.
This relay supports screw-type terminals for both the main current circuit and the auxiliary and control circuit.
The relay has a blocking voltage rating of 800 V for the thyristor in the main contacts, and a voltage slew rate of up to 1,000 V/µs.
