• The Sollatek SVS boosts low voltage. • The Sollatek SVS reduces high voltage. • The Sollatek SVS disconnects the load (fridge, TV, PC etc) using its built-in Automatic Voltage Switcher, when mains stabilisation within acceptable limits is outside its capability (available as an option in 3 phase models). • Automatically reconnects the load, but only after the mains has remained within acceptable limits for a period of three minutes.† This is to allow neutralisation of compressor gases, critical in such applications. • Has a very wide voltage response range of 140V to 295V (-25% to +19%). (see table of input and output voltage responses). • Incorporates intelligent delay to reduce off-time when the appliance has been switched off for over three minutes.† • Uses a unique zero voltage switching technique to achieve clean pure stabilised power. • Incorporates full spike protection. • Frequency compensated measurements. • Frequency and voltage measurement smoothing in software to filter noise. • Fault detection - senses if the measurements being made are unreasonable and disconnects output. Red and yellow LEDs flash alternately to indicate a fault.
