TERMINOLOGY AND ABREVIATIONS
Buffer Module Short term buffer system with DC-In-/Output. Utilizes capacitors as energy source
DC-UPS Uninterruptible power supply system with DC-In-/Output. Utilizes batteries as energy source
Normal mode Describes a condition where the capacitor is charged, the input voltage is in range and the
output is loaded within the allowed limits.
Buffer mode Describes a condition where the input voltage is below the transfer threshold level, the unit is
running on capacitor (buffering) and the output is loaded within the allowed limits.
Charging mode Describes a condition where the capacitor is being charged, the input voltage is in range and
the output is loaded within the allowed limits.
Inhibit mode Describes a condition where buffering is disabled on purpose (e.g. for service actions)
T.b.d. To be defined, value or description will follow later.
AC 24V A figure displayed with the AC or DC before the value represents a nominal voltage with
standard tolerances included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
24Vac A figure with the unit (Vac) at the end is a momentary figure without any additional
tolerances included.
may A key word indicating flexibility of choice with no implied preference.
shall A key word indicating a mandatory requirement.
should A key word indicating flexibility of choice with a strongly preferred implementation.
