The ST regulators are an advanced AVR is fully digital controlled. Compatible with all load types and offering independent phase control, they deliver ultra-fast response times in precisely correcting under / over voltages, sags and surges - making them ideal for highly sensitive / mission critical loads and applications. Should the incoming voltage rise or drop, the ST series stabilizer will automatically control the output to ensure the voltage reaching the load equipment always remains constant at the requisite voltage.
ST series AVRs provide comprehensive protection for the load against overcurrent, short-circuit, spikes and surges. The term overcurrent describes a sharp and fast rise in current over a short period of time (fractions of a second) . A short-circuit condition means a circuit allows the current to flow through an unintended path with very low electrical impedance. A sudden rise in voltage lasting three nanoseconds or more is generally classed as a “voltage surge” while a spike more typically refers to shorter-lived increases in power.
Energy efficiency for automatic voltage stabilizer is so important because they can influence UPS energy efficiency and can directly impact energy costs. The lower the efficiency, the more heat that is generated and the more cooling that is required in the room, driving up capital costs and the ongoing operational expenses of the cooling system.ST series AVR perform at a very high efficiency of > 97%
ST series stabilizers can be installed in areas with difficult access, subject to critical environmental conditions due to cold, high temperatures, humidity, atmospheric discharges. Accurate and severe tests on each system and the use of high technologies permit our products to achieve an MTBF (mean time between failures) of 500,000 hours. The long-life and low cost of ownership makes ST series stabilizers a very economical and reliable solution.
