Voltage stabilizer KEMOT PROavr-20k

Product detailed description

Protect your equipment from power surges
In single-phase mode, each phase can operate independently. Regardless of the network load and output voltage fluctuations, the KEMOT PROavr-20 voltage regulator maintains the voltage at 230 V ±3%, thus ensuring efficient operation of all devices, including those that are sensitive to the quality of the network voltage. The regulation is automatic, ensuring high accuracy of the output voltage. A fault in one phase does not affect the operation of the other phases.

Three-phase mode
In three-phase mode, maintaining phase balance is critical. The stabilizer monitors and regulates the voltage in each phase to ensure they are consistent with each other. It compensates for input voltages that are too high or too low and, once stabilized, feeds the voltage to the output. If any phase fails or disconnects in this mode, the device activates protection and prevents voltage from being applied to the output, indicated by a "PHASE FAILURE" indicator.

How does the KEMOT PROavr-20 voltage regulator work?
The KEMOT voltage regulator is a device designed to maintain a set output voltage of 230 V. Its purpose is to increase or decrease the input voltage that is too low or too high, and to ensure that the output voltage remains within the permitted range, and to prevent energy spikes that could be dangerous for connected equipment. The design of the regulator is based on a toroidal transformer, which ensures stable operation of the device.

Voltage regulator with servomotor
The KEMOT PROavr-20 voltage regulator maintains the voltage with high accuracy up to 3%. This high level of accuracy is the result of servo motor based technology.

BYPASS switch
The device is also equipped with a "bypass" function, i.e. a switch that bypasses the operation of the controller, allowing it to be isolated and seamlessly fed from an external source to the home mains.

BACKUP function
If you need a voltage regulator for devices with high inrush currents, choose a model with a delay switch. The KEMOT PROavr-20 model features a delay switch with a range of 6 to 180 seconds, which reduces the risk of damage to connected equipment at high inrush currents. The KEMOT PROavr-20 is also protected against overvoltage, undervoltage, overload, overheating and short circuit.

Easy transport
To make it easier to move and position the KEMOT stabiliser in the right place, it is equipped with four sturdy castors. These castors allow easy transport of the equipment to different locations, greatly simplifying its operation and maintenance.
