FAQs

 

What is the main function of the TNDZ Pillar Type AC Automatic Regulator?

It maintains a stable output voltage to protect sensitive electrical equipment from voltage fluctuations, ensuring continuous and efficient operation.

 

What are the differences between TNDZ and TNSZ models?

The TNDZ series supports single-phase (220V) loads, while the TNSZ series serves three-phase (380V) applications, offering higher power capacities for industrial use.

 

How does it protect against power irregularities?

It automatically detects over-voltage, under-voltage, and phase faults, cutting off power and triggering alarms when limits are exceeded, then safely restoring once voltage normalizes.

 

How fast can it respond to changes in voltage?

The TNDZ stabilizer reacts in under 1.5 seconds for voltage changes up to 25V, guaranteeing smooth and uninterrupted equipment operation.

 

What are its main applications?

It’s ideal for telecommunication systems, broadcasting networks, elevators, CNC machinery, semiconductor processing, and factory automation lines, where voltage stability is crucial.
