Note: The minimum power of a load to take inverter out of sleep mode (Power Saver On) is 25 Watts.
The Global LF Series is designed with extraordinarily low idle power consumption which is only a mere 2-3
% of its rated power.
When in the search sense mode, the green power LED will blink and the inverter will make a ticking sound.
At full output voltage, the green power LED will light steadily and the inverter will make a steady humming
sound. When the inverter is used as an “uninterruptible” power supply the search sense mode or “Power
Saver On” function should be defeated.
Exceptions
Some devices when scanned by the load sensor cannot be detected. Small fluorescent lights are the most
common example. (Try altering the plug polarity by turning the plug over.) Some computers and
sophisticated electronics have power supplies that do not present a load until line voltage is available. When
this occurs, each unit waits for the other to begin. To drive these loads either a small companion load must
be used to bring the inverter out of its search mode, or the inverter may be programmed to remain at full
output voltage (Power On mode).
2.5.5 Protections
The Global LF series inverter is equipped with extensive protections against various harsh situations/faults.
These protections include:
AC Input over voltage protection/AC Input low voltage protection
Low battery alarm/High battery alarm
Over temperature protection/Over load protection
Short Circuit protection (1s after fault)
Back feeding protection
When Over temperature /Over load occur, after the fault is cleared, the master switch has to be reset to
restart the inverter.
The Low battery voltage trip point can be customized from a defaulted value of 10VDC to 10.5VDC thru
SW1 on the DIP switch.
The inverter will go to over temp protection when the heat sink temp ≥ 221℉, and go to Fault
(shutdown Output) after 30 seconds. The switch needs to be reset to activate the inverter.
The Global LF series Inverter has back feeding protection which avoids presenting an AC voltage on the AC
input terminal in Invert mode.
After the reason for the fault is cleared, the inverter needs to be reset to start working.
Peak Current 50Amp, duration 1 Second of peak and the 3 cycle RMS value is 100Vac.
