SN-300 - The plug-in voltage regulator is designed to protect sensitive equipment against interference from the mains, generated by various types of machines, lighting fixtures, etc. It suppresses among other things voltage surges, harmonic disturbance and voltage changes. The design of the regulator is based on a transformer, which is always saturated , which gives a good compensation of voltage variations. The SN-300 voltage regulator maintains a stable voltage of 230V. It ensures the correct operation of devices sensitive to fluctuations in voltage. In addition, the regulator protects the connected equipment from sudden increases or decreases in supply voltage (more than 275V or less than 155V) by disconnecting fast its power supply. The rated output power for a single-phase regulator should be matched to the receiver power (satellite TV, RTV consumer electronics, computers, controllers of heating equipment, medical equipment, machinery and other devices). The basic principle is to leave a certain margin of power reserve (20-50% depending on the load). The output power of the SN-300 voltage regulator is 300W!
