| Option “dd” |
(decoupling diode): For redundant operation the outputs of two or
more units are paralleled behind de-coupling diodes so that an internal fault of
one module does not affect the operation of the others. These diodes cause power
losses. |
|---|
| Option “cs” |
(active current sharing): An additional control circuit provides active
current sharing via an interconnecting wire between converters that operate in
parallel. Active current sharing should be used for multi-output units operating in
parallel.
|
|---|
| Option “csi” |
(current sharing interrupt): Option "csi" will effect the removal of the
"cs" signal. Should there be an instance where a unit is not supplying the load,
then the effect of its "cs" signal is removed, and the load voltage is unaffected by
this condition. |
|---|
| Option “h1” |
(inhibit): A terminal connected to the negative input line also shuts off the
converter. This can also be used in conjunction with a thermal trip which shuts the unit
down. |
|---|
| Option “h2” |
(inhibit): Operation of the unit is inhibited if a voltage signal
(5V/10mA) is applied in reference to the negative line of the (main) output. |
|---|
| Option “rco” |
(reducing current limiting at over temperature) A circuit reduces the
current limiting level at higher temperature (to be specified). |
|---|
| Option “d” |
(DC-ok, one output): A logic signal is given if the output voltage (main
output in multi-output systems) is below the specified limit. |
|---|
| Option “m” |
(DC-ok, all outputs): In multi-output systems a logic signal is provided
if the voltage of any output is below the specified limit. |
|---|
| Option “ac” |
(AC ok) A logic signal connected to relay contacts is given if the
output voltage of an inverter is below the specified limit. |
|---|
| Option "y" |
(sys-reset): This logic signal is a combination of power fail and DC-ok
as specified for VME systems. |
| Option "r" |
(relay): A relay instead of a logic signal is provided for failure
indication. |
