INPUT OPTIONS | |
---|---|
Option “i” | (inrush current limiting): A thermistor is connected in series with the input lines which changes its resistance from high to low when it gets hot. It does not reduce the current surge if the input power is interrupted for a short period of time not allowing the thermistor to cool down. Thermistors are fitted as standard to all mains input models except for 1-phase input of models > 2.5kW. Thermistors are available up to 45A. For higher input current an electronic inrush current limitation can be offered. |
Option “ie” | electronic inrush current limiting An electronic circuit limits the inrush current. |
Option “sd” | (series diode): A series diode protects the module against input voltage of wrong polarity (additional power losses). |
Option “ad” | (anti-parallel diode): To avoid the power losses of a series diode a diode is provided with opposite polarity in parallel to the input blowing an internal or external fuse if the module is connected to a supply with wrong polarity. |
Option “au” | (auto-ranging) For standard dual AC input models the range of 115/230Vac is to be selected by connecting the input line to different pins on the connector. With auto-ranging the unit senses the input voltage and provides automatically the correct connection. |
Option “p” | (power fail): A signal (logic or relay) is given if the input voltage (AC or DC) drops below the specified limit. In AC input units we sense the rectified input voltage so that a power fail alarm will not be triggered if at light loads mains power returns before the input capacitors are substantially discharged. |
Option “r” | (relay): A relay instead of a logic signal is provided for failure indication. |
output options | |
---|---|
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 inparallel. |
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. |
environment options | |
---|---|
Option "t" | (tropical protection):The unit is given additional protection by a heavy coat of varnish on the printed circuit board(s) and components. |
Option "c" | (extended temperature range):The circuit is designed and tested for operation at an ambient temperature as low as –40 °C. |
Option "ms" | (increased mechanical strength): Screws are secured by Locktite and heavy components are fastened by ties and/or glue. Modules with the "ms" option meet the standard EN61373 regarding shock and vibration. |
mechanical options | |

Standard mounting | "Eurocassette" pluggable module for 19" sub-racks |
