TM SVEN presents its new products: AVR PRO LCD 5000, AVR PRO LCD 8000 and AVR PRO LCD 10000 wall-mounted automatic voltage regulators.

Wall-mounted automatic voltage regulator of AVR PRO LCD series are designed to supply stabilized voltage to household electrical appliances in conditions of voltage deviations of the single-phase power supply network higher than permissible value. Automatic voltage regulators provide protection of powered electrical devices against excessive voltage deviation and provide their safe connect when power supply failures are over.

The extended range of input voltages (from 140 V to 260 V) provides the power supply to devices even in conditions of critical power supply state. The wide product line of AVRs with different rated capacities up to 8 kW makes it possible to select an optimum model for specific user’s purposes.

The application of a microprocessor in the AVR electronic circuit enables to realize the large set of functions: real input/output voltage displaying on the LED indicator of the front panel (see the figure below), AVR operation state displaying, PAUSE function with the adjustable switching-on delay, intellectual protection against high/low voltage. Apart from the above listed functions AVRs provide protection against overload and have the built-in thermal protection of the transformer.

AVR PRO LCD series models have holes for wall mounting. They are structurally implemented in firm metal cases, due to which they can be placed even inside technical premises such as switchboard rooms, repair shops, boiler rooms, etc. Automatic voltage regulators are connected to the power supply network by means of a terminal block tree located in the closed compartment at the AVR bottom.

Note. It is forbidden to connect AVR PRO LCD regulators to standard mains sockets! They are to be connected to the mains, as well as devices-consumers are to be connected to regulators, via terminals and relevant cables (not included). Regulators can be mounted on the wall and connected to the mains only by qualified specialists. Make sure that vent holes and/or the fan are not to be closed during the mounting.

Before installing the AVR, please make sure that total power of all voltage consumers is lower than AVR power. Taking into account the starting load and power factor of consumers, it is necessary to apply power margin factor of 1.2–1.5, but for such equipment as air conditioners, fridges, etc. it should be 1.5–2.

ATTENTION! When selecting an AVR, it is necessary to know that at reduction of input voltage value the input current value increases, which means that maximum power of AVR is reduced too! Such dependence is shown in the graph below:
