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

• SIDOOR AT40 and SIDOOR ATD400V Elevator Door Drives
• SIDOOR ATD400W and SIDOOR ATD410W Machine Tool Door Drives
• SIDOOR ATD400S Platform Screen Door Drive

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).
