Power supply NT-T-6.5 - 230 V AC / 24 V DC, 6.5 A

Aumüller NT-S-6.5 Power Supply 230 V AC / 24 V DC, 6.5 A (660007)

The Aumüller NT-S-6.5 (660007) is a switched-mode power supply designed to supply and control 24 V DC window actuators for everyday natural ventilation. With an output current of 6.5 A, it is suitable for applications requiring more power than a small 24 V power supply can provide.

24 V actuator control from the 230 V mains side

OPEN and CLOSE operation is controlled via the 230 V AC mains supply, while the NT-S-6.5 provides the required 24 V DC power for the connected window actuators.

This makes the unit a practical solution for conventional ventilation installations with one ventilation line where a separate ventilation control unit is not required.

6.5 A for larger actuator groups

With an available output current of 6.5 A, the NT-S-6.5 can supply larger or more powerful groups of 24 V actuators.

Where additional capacity is required, Aumüller allows up to eight NT-S-6.5 power supplies to be connected in parallel, making the system scalable for larger natural ventilation installations.

The surface-mounted ABS enclosure has an IP54 protection rating.

NT-S-6.5 compared with NT-T-2.5

The NT-S-6.5 is a switched-mode power supply providing up to 6.5 A and is intended for applications with a higher actuator power requirement.

The smaller NT-T-2.5 (660009) uses a transformer and provides an output current of 2.5 A.
