Automatic Voltage
Switch
Model: AVS5D
Introduction
The AVS5D is a 5 amp rated automatic voltage switch that protects appliances
from high voltages, low voltages (including brownouts), power surges, spikes and
lighting. It does this by switching off connected equipment if the power flowing to it
goes outside preset limits, and will reconnect automatically when power returns to
normal (except in the case of an overload condition). There will be a delay before
the reconnection to ensure power stability.

change digital display mode. During normal operation, you can press F2 to
display the load. After 3 seconds, the switch returns to the voltage display.

Digital Display Shows voltage, wattage, status and settings.
A) U-H Output Overvoltage Protection Status
When output voltage exceeds the preset limit and doesn’t return to within
the preset limits after 1 second, your equipment will be disconnected by
the switch. U-H will flash on the display every .5 seconds as long as the
overvoltage condition exists.
B) U-L Output Undervoltage Protection Status
When output voltage goes lower than the preset limit and doesn’t return to
within the preset limits after 1 second, your equipment will be disconnected
by the switch. U-L will flash on the display every .5 seconds as long as the
undervoltage condition exists.
C) P-H Overload Protection Status
When the load exceeds the preset range (nominally 110-120%) and lasts
longer than 6 seconds (within this 6 seconds no action will be taken by the
AVS5D), the switch will disconnect from power. P-H will flash on the display
every .5 seconds as long as the overload condition exists.
When the load exceeds the preset range (nominally 150%) and lasts longer
than 1 second, the switch will disconnect from power. P-H will flash on the
display every .5 seconds as long as the overload condition exists.
Overload Faults - You must power cycle the unit to restore the current flow.
The unit does not reset automatically from this type of fault.
D) Start Up Delay
When first powered up, the unit will count down a set number of seconds
(default is 6) before monitoring voltage.
E) Parameter Setting Codes
E-0 Delay setting
E-1 Undervoltage protection value setting
E-2 Overvoltage protection value setting
E-3 Overload protection value setting
E-4 Displays output voltage or loading power value after startup
(U= voltage, P= watts)
E-5 Restores default settings
Note: The code and value flash alternately every second while changing settings.
