The SIDOOR NT40 switch mode power supply is operated with 230 V AC (± 15 %), 50/60 Hz, to power the following SIDOOR door controllers:

• SIDOOR AT40 and SIDOOR ATD400V elevator door drives
• SIDOOR ATD400K cold room gate drives
• SIDOOR ATD4xxW machine tool door drives

It is especially suitable for door systems with high door weights.

On the output side, the power supply unit delivers a voltage of 36 V DC (± 3 %) SELV at a rated output power of < 100 W.

In order to enable fast acceleration/deceleration of the doors by the controller, the device can briefly (< 2 s) deliver a current of 15 A (corresponds to a short-time power output of 540 W).
