OPERATION
The SVC is designed to provide a constant supply at the rated
current for 12VDC equipment. The SVC is protected from a variety
of connection and application errors by a range of built in devices.
In most instances these errors are revealed by the diagnostic
indicator and can be corrected without having damaged the unit.
The SVC is protected in the following situations:
• Low Input Voltage If the input voltage falls below 17VDC the
SVC will be disabled. When the input voltage rises above this
setting the output supply will be restored.*
• High Temperature In the event the SVC exceeds the preset
temperature limit, the unit will be disabled. When the
temperature decreases the output supply will be restored.*
• Output Short Circuit If the output supply is short circuited
the SVC will be disabled. When the short is removed the
output supply will be restored.*
• Output Overload If the maximum current rating is
continuously exceeded the unit will be disabled. When the
load is reduced the output supply will be restored.
• Input Reverse Connection If the input terminals are reverse
connected the SVC will become inoperable. The input circuit
is diode controlled and protected by an internal fuse which is
not user serviceable.
• Output Over Voltage A Zener crowbar circuit prevents the
output supply from high voltage. The circuit is protected by
an internal fuse which is not user serviceable.
• Transient Input Voltage A purpose designed circuit filters
out surges and spikes.
* Refer diagnostics and fault finding section on next page for
trouble-shooting these problems.
