Overview:
The LSVR low-voltage automatic voltage regulator automatically adjusts the output voltage according to the input voltage,
improves the voltage qualification rate, and ensures the quality of power supply. There is no need to extend the 10kV line and
increase the distribution transformer. The voltage output of this product is a sine wave, which allows short-term overload.
It is suitable for various low-voltage applications and solves the problem of low voltage qualification rate for distribution network users.
Working principle?
The intelligent controller detects the voltage on the load side of the regulator and compares it with the set qualified voltage range.
When the load side voltage is higher than the upper limit of the voltage pass, the control gear is lowered. When the load side voltage
is lower than the lower limit of the voltage pass, Adjust the gear up so that the voltage on the load side is within the acceptable range.
Features:
--Wide voltage regulation range, obvious voltage regulation effect, high voltage regulation precision.
u--With multiple protection methods such as over-current, quick-break, overload, over-temperature, etc., once the regulator
fails, it will automatically enter the bypass state to ensure the normal power supply of the line.
--The intelligent controller can be equipped with GPRS remote communication function, so that you can grasp the operation of
the regulator in real time without leaving home.
--uSingle-phase and three-phase products. Three-phase products can be independently adjusted according to the voltage of
each phase to ensure that the output voltage of each phase is qualified.
-- Simple structure, light equipment, single pole, wall mounting and other installation methods can be used to facilitate on-site
construction.
