Under-Voltage
When the input voltage drops below the operating range of the unit (See Section 1.2.1;
absolute minimum input of 20VDC) the unit senses an under-voltage condition and disables
the output. The unit will dynamically monitor the input voltage such that if the input returns
to within the normal operating range, the output will be enabled and allow the unit to
operate normally. Under-voltage will not activate the fault status output.
Over-Temperature
The TI250 Series Static Inverter incorporates an internal temperature sensing device that
continually provides monitoring and feedback to the control circuits. When the unit senses
an internal condition that exceeds maximum temperature ratings, the output is disabled and
the fault output will indicate. The inverter will continue to remain shut-down in a fault
condition until the temperature returns to within acceptable limits. This over-temperature
reset occurs automatically without external intervention required.
Short Circuit And Over-Current
The TI250 Series Static Inverter is capable of surviving a short circuit or over-current event
without permanent damage or effect to long-term reliability. The unit can provide over its
rated power output up to 375 watts for over 30 minutes (until over-temperature shutdown
occurs).
The inverter monitors the AC output on a pulse-by-pulse scenario to determine a short-
circuit or over-current situation. If detected, the output is limited by clipping the AC sine
waveform, limiting the power output. If the short-circuit or over-current situation continues
for more than a few seconds, the inverter will turn-off the AC output and indicate a fault on
the fault output line.
Ground Fault Protection (-1 only)
The TI250 Series Static Inverter monitors the AC output for indications of current imbalance
between the two AC output lines. Should a ground fault be detected, the AC output will be
disabled and the fault output will indicate. Remove all inverter loads before re-enabling the
inverter.
Fault Shutdown and Indication
The TI250 Series Static Inverter monitors the AC output load, its internal temperature, and
operation status. Should the load be excessive or the inverter become too hot, the inverter
will disable the AC output and indicate a fault status on the fault output. If the inverter is in a
fault state, a LED connected as shown in the wiring diagrams will be lit.
To reset the inverter and clear the fault: 1) Remove all inverter loads before re-enabling the
inverter, 2)Re-enable the inverter by switching the inverter OFF for four seconds, and then
back to ON. NOTE: If the inverter is over-temperature it will not re-enable until it has
cooled. Fault can also be cleared by cycling power to the inverter.
