SCR Servo Motor Type Regulator
The voltmeters and ammeters are all digital. The voltmeter normally shows the output voltage but it switches over to input voltage temporarily when the “Display” button is pressed. When the regulator is first switched on the output is not connected until the output voltage is regulated and checked. If for any reason the output voltage goes outside the set safety limits it cuts off the output. By pressing the “Precision” button you can change the protection from High sensitivity to Low sensitivity and vice versa. The appropriate letters H and L are displayed temporarily on the bottom display. The output is cut off automatically if the regulator overheats. The normal input voltage is 150 to 260 volts, output 220 volts adjustable. All motors have automatic wind back on switch off.
