In industrial environments the power supply is quite noise due to a variety of loads. Operating critical, expensive and sensitive electronic devices in such environments put them at risk. Harmonics, voltage fluctuations, voltage peaks, mains failure, abrupt low voltages and blackouts are common in such environments. Lightning and electrostatic discharges are another threat to sensitive data equipped with CMOS chips. The solution is to use Lento DSP sine wave online UPS. Lento online UPS DSP power supplies incorporate inverters that draw power from the mains and deliver highly stabilized, noise-free supply for sensitive electronic equipments. Simultaneously, the batteries are kept in a state of full charge through a sophisticated monitoring and control circuit. Lento DSP UPS deliver 50 Hz 230V stable supply with variations kept within tight limits of 1-2%. Power automatically shifts to battery backup in case of over voltage of mains, low voltage, rapid fluctuations or total failure. This makes it ideal for computers and other sensitive equipments for seamless transition that avoids resets.
