2. Product Protection Functions


Have a general idea of protection functions desinged with the voltage regulator throught the chart below:


Over-voltage protection If the output voltage is too higher than the rated output voltage, the air switch would trip and the stabilizer would be powered off automatically.
Over-current/load protection If the working current and loads are too much more than the rated capacity, the voltage stabilizer also would stop working so as to protect the product itself.
Under-voltage protection The same as the over-voltage protection, if the voltage is too lower than the rated one, it would power off.
Short circuit protection If there happens a short circuit, it would function and stop working immediately.
Time delay protection Five-second time delay before the voltage is output to the load equipment so as to protect it from being damaged by higher or lower voltage.

4. Relevant Products Recommended


There are many types of voltage stabilizer which could be chosen. The following description shows you several types:


Three phase high precision full automatic voltage regulator: TNS(SVC)-6KVA to TNS(SVC)-100KVA.


Single phase high precision full automatic voltage regulaotr: TND(SVC)-500VA to TND(SVC)-50KVA.


Three phase high power compensated voltage regulator: SBW-30KVA to SBW-F-3000KVA.



5. Product Advantages


Fast response speed: the voltage regulator reacts within one second when the voltage fluctuates less than 20 volts.


High output precision: the output accuracy is ±2% of the rated voltage.


Strong load bearing capability: the rated capacity of the voltage regulator is 45KVA, which enables it to bear a lot of electrical equipment.


Long service life: the service life of this voltage regulator could be more than 15 years.


Wide input voltage range: the normal input voltage range is 380V±20% of the rated voltage. Wider range could be customized.


Clear data display: the input and output data could be shown on the pointer meters, which is very convenient for data monitoring.
