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 high inrush current caused by built-in capacitors. Switch- on time may increase to 5s. This is realized by a series pass transistor or depending on the input voltage by thyristor softstart..
Option “sd” Reverse polarity protection for DC input by series diode: A series diode protects the module against DC input voltage of wrong polarity. However, this also causes extra losses and reduces the overall efficiency..
Option “ad” Reverse polarity protection for DC input by anti parallel diode: To avoid the power losses 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 of wrong polarity.
Option “au” Auto-ranging: For standard dual AC input models the range of 115 / 230 V AC 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.
OUTPUT OPTIONS
Option “dd” Decoupling diode: A series diode built into the units output allows paralleling of 2 or more units for redundancy or higher power or battery charging. For control purposes the anode of the diode is also available at the output connector. It cannot be loaded ≥ 0.5A. The sense signal is taken partially from the anode and partially from the load/cathode of the decoupling diode. This guarantees starting and operating under all conditions, but it also effects the regulation accuracy of 2%. In this way it gives a load sharing of 15-30% between the paralleled units.
Option “cs” Active current sharing: An additional control circuit provides active current sharing via an interconnecting wire between converters that operate in parallel. The output lines of the converters have to be in “star point” connection
Option “csi” Current sharing interrupt (“cs” included)“csi” will effect the removal of the “cs” signal from the load voltage common connection. Should there be an instance where a unit is not supplying the load, then the effect of its current sharing signal is removed, and the load voltage is unaffected by this condition. In terms of calibration the same criteria follow as for parallel operation.
Option “icsi” Current sharing interrupt (“csi” included), galvanically isolated: The inclusion of “csi” (current sharing interrupt) and the galvanic isolation is the optimum set up for systems with high power or high currents, were the voltage drop on the power wiring could influence the cs signal.
Option “h1” Inhibit by external closing contact, signal referred to input: The operation of the unit is inhibited when a voltage signal is applied in reference to the negative line of the input. This can also be used in combination with a thermal trip, which shuts the unit down.
Option “h2” Inhibit by voltage signal, signal referred to output: Operation of the unit is inhibited if a voltage signal (5V / 10mA) is applied in reference to the negative line of the output
Option “h3” Inhibit by closing contact, signal referred to output: The operation of the unit is inhibited when a voltage signal is applied in reference to the negative line of the output. This can also be used in combination with a thermal trip, which shuts the unit down. Please note: Only relevant solution for inverters.
Option “rco” Reducing current limiting at over temperature: A circuit reduces the current limiting level at higher temperature (to be specified).
Option "rd" Reverse polarity protection for DC output: by reverse diode with external fuse.
SIGNAL OPTIONS
Option “pr” input voltage supervision (power ok) incl. relay contacts: A logic signal is given if the input voltage (AC or DC) drops below the specified limit. In AC input models the rectified input voltage is sensed so that a power fail alarm can be avoided if at light load mains power returns before the input capacitors are substantially discharged. A relay contact is provided for failure indication
Option “dr” output voltage supervision (DC ok) incl. relay contacts: A logic signal is given if the output voltage is below the specified limit. A relay contact is provided for failure indication. DC ok level: 5V output: 4,75V all other voltages: 90% of adjusted voltage
Option “cf” charger / converter fail supervision incl. relay contacts: A logic signal is given if the input voltage, the auxiliary voltage of the primary side and the current of the primary side exceed or go below a specified range. A relay contact is provided for failure indication.
Option “ac” AC ok for inverter including relay contacts: A logic signal is given if the output voltage of an inverter is below the specified limit. A relay contact is provided for failure indication
ENVIRONMENTAL OPTIONS
Option "t" Tropical protection: The unit is given additional protection by a heavy coat of varnish on the printed circuit board(s) and on components to achieve 99% RH, non condensing.
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.
