AIMS LF Series - Auto Frequency Adjust; Power Saver

input terminals to when the transfer is made. This delay is built in to provide time for a generator to spin-up
to a stable voltage and avoid relay chattering. The inverter will not transfer to generator until it has locked
onto the generator’s output. This delay is also designed to avoid frequent switching when input utility is
unstable.
2.5.4 Auto Frequency Adjust
The inverter is designed with Auto Frequency adjust function.
The factory default configuration for 220/230/240VAC inverter is 50Hz, and 60Hz for 100/110/120VAC
inverter.
If the output frequency needs to be changed this is done by putting in a valid input Power Source to the
inverter’s input lines. Once the inverter validates the input, the output will automatically change.
NOTE: The inverter will output factory set freq after it restarts. Customers who can only accept one freq
should specify the freq when ordering.
2.5.5 Power Saver
There are 2 different working statuses for our Global LF
inverter: “Power On” and “Power Off”.
When the power switch is in “Unit Off” position, the inverter
is powered off.
When the power switch is turned to either of “Power Saver
Auto” or “Power Saver Off”, the inverter is powered on.
Power saver function is designed to conserve battery power
when AC power is not or rarely required by the loads.
In this mode, the inverter pulses the AC output looking for an
AC load (i.e., electrical appliance). Whenever an AC load
(greater than 25 watts) is turned on, the inverter recognizes the need for power and automatically starts
inverting and output goes to full voltage. When there is no load (or less than 25 watts) detected, the inverter
automatically goes back into search mode to minimize energy consumption from the battery bank.
In “Power saver on” mode, the inverter will draw power mainly in sensing moments, thus the idle
consumption is significantly reduced.
The inverter is factory defaulted to detect a load for 250ms every 30 seconds. This cycle can be customized
to 3 seconds thru SW3 on the DIP switch.

Note: The minimum power of a load to take inverter out of sleep mode (Power Saver On) is 25 Watts.
