    Power Management Series

    Irregular voltages or spikes can be severely harmful to your equipment.
    The compressors on normal fridges will burn out if the voltage is too low [below 190V]. TV’s, Hi Fi’s, Computers, Monitors, Fax machines, Photo copiers, and more, are all likely to sustain damage if the 220V supply suddenly rises to above 250V.  
    The high and low [under/over] voltage protector will protect equipment operating between 220—240 volts AC and will safely pass a maximum current of 15Amps. If the voltage goes below 190V or it goes above 250V, the unit will switch off your appliance. The unit will remain off until the voltage returns to normal. Should the voltage have dropped for a split second the unit will switch off but will not switch on until the delay period has passed [minimum of 30 seconds] standard delay is 40 seconds.

    This product has built in surge protection as well as the power monitoring features to further enhance the protection levels of your equipment. On detection of a surge or spike the unit will see it as a high condition and instantly switch off.

    Operation
         Plug the unit into the wall socket and switch on. Allow +/- 10 seconds for the unit to calibrate, the display will show a line running around the outside of the square while calibrating. On completion a number will be displayed for example ‘5’ which indicates that the voltage is between 221 and 225. See the top of the Unit for the complete table. Should the voltage be too low the unit will display an ‘L’ and will not switch on. The same applies if the voltage is too high and ‘H’ is displayed and the unit will remain off.

    These units are available in three configurations as shown. Each has been designed to cater for certain specific needs. The functionality of all three units are the same. The difference is the installation method.




    Indicator Lights
    Blue on—all is OK
    Number displayed to indicate voltage range
    Red on—high voltage failure
    ‘H’ shown in display
    Red on—low voltage failure
    ‘L’ shown in display
    Red & Blue off—no power to unit or unit needs to be replaced after protecting your equipment .
