Stabilizing Automatic Voltage Regulator

four stage auto-transformer line conditioner with voltage regulation
		SLc-E Series  230V, 600VA, 1200VA and 1800VA

This automatic voltage regulator provides stable power even when the ac mains or back-up generator voltage is extremely low or high. Typical Applications for the SLc E Series SLc Series conditioners provide low-cost ac line protection for computers, point-of-sale terminals, copiers, data acquisition and control systems, as well as other data processing equipment. SLc’s can also be used to protect low-cost stand-by UPS to prevent discharge of UPS batteries due to low- or high-voltage transfer to inverter. Key SLc E Series benefits TSi Power’s SLc E Series regulated output protects switch-mode power supplies from failure caused by unstable ac mains. SLc provides three-way surge protection and reduction of surge voltage. The SLc line conditioner can be used between a UPS and the ac mains to provide even greater protection for the connected equipment, while saving the UPS's internal batteries for true black-outs. How the SLc E Series four stage automatic voltage regulator works The SLc E Series incorporates a four-winding auto-transformer, which provides four levels of line regulation: two boost-stage and one buck-stage. Even when the input voltage varies between 150 to 280V, the output is regulated to within 200 and 250V, well within the range of most equipment. SLc E operation is monitored by four status LEDs, indicating normal, boost 1, boost 2 and buck stages of voltage regulation. The front panel power switch turns the SLc E on and supplies power to the equipment.
