PROTECTIVE FEATURES
4.2.1 Remote On/Off
The TI1200 Series Static Inverter incorporates a remote on/off feature that allows the user to
enable or disable the output of the unit. By providing a ground on the appropriate pin (See
Table 3.3.2) the user, via a remote mounted switch or similar method, can enable the output
of the unit. The unit can be similarly disabled by removing the ground signal (open circuit) to
the same pin.
4.2.2 Over-Voltage
When the input voltage exceeds the operating range of the unit (See Table 1.2; Input
Voltages) the unit senses an over-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.
4.2.3 Under-Voltage
When the input voltage drops below the operating range of the unit (See Table 1.2; Input
Voltages) the unit senses an under-voltage condition and disables the output. The unit will
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.
4.2.4 Over-Temperature
The TI1200 Series incorporates an internal temperature sensing device that provides
monitoring to the control circuits. When the unit senses an internal condition that exceeds
maximum temperature, the inverter output is disabled and the internal cooling fans will
continue to operate. The unit output will again be enabled when the temperature returns to
within acceptable limits. This over-temperature reset occurs automatically without any
external intervention required.
4.2.5 Short Circuit and Over-Current for the 6431200-1, -2, -3, -5, and -6
The TI1200 Series is will tolerate short circuit or over-current events without permanent
damage or effect to long-term reliability. The unit can provide, over its rated power output, up
to 110% of rating or 1320 VA continuously (660VA for the 6431200-5). The power output is
limited by temperature, input voltage and altitude as shown in Figures 4.1, 4.2, and 4.3. The
TI1200 senses output current pulse-by-pulse to determine a short circuit or over-current
situation.
