    1V. Control Mode The NGPS unit can be controlled in three main different ways, hereafter listed: • LOCAL control: the unit can be controlled directly via the front panel color display and the navigation switch. When the unit is set in LOCAL mode, it is possible to perform readings and monitor the unit from the remote interface also but any setting command is denied;...

  • Page 18: Update Mode

    NGPS – User’s Manual Installation Update Mode The current or voltage setting of the unit can be performed in four different modes: • NORMAL: the update of the set-point (current or voltage, depending on the regulation mode, see Section 1.3.1) is performed as soon as a new set-point is received via the remote, local or fast interfaces;...

  • Page 19: Interlock And Status Signals

    NGPS – User’s Manual Installation 1.4 Interlock and Status Signals The NGPS module has four configurable dry-contact input interlocks and two output status signals that are directly available on the D-Sub 15 Pin Female connector on the rear panel (Figure 4).

    Interlock Identification Name The NGPS also allows associating a name to the interlocks in order to read form the remote interface or to display on the local display the interlock condition name. The intervention names are stored in the field #93 for Interlock #1, in field #95 for Interlock #2, in field #97 for Interlock #3 and in field #99 for Interlock #4.

  • Page 22: Remote Sensing

    Do not connect +S to – or –S to +. The NGPS mounts a voltage-sensing connector on the rear panel that allows using the voltage sensing feature, especially when using the power supply in C.V.
  • Page 23 It is strongly suggested to use twisted cables when using the remote sensing feature in order to minimize possible noise pick-up. The NGPS is shipped with the mating connector for the remote sensing in the factory-default configuration: +S and + pins are shorted as well as –S with –. This configuration performs the remote sensing directly at the output connector of the power unit.

  • Page 26: Analog Control Input

    Figure 9: Trigger thresholds Analog Control Input The analog control input allows controlling the NGPS unit almost as an “amplifier”. This input is labelled as “AN CTRL”. This input accepts signals ranging from 0V to +10V and generates an output which is proportional to the input signal: zero output for a 0V input and Full-Scale output for a +10V input.

    LED and to turn-on the module output again (only if the fault condition/cause has been removed); • C.C. (blue): if turned on, the NGPS is working in constant-current mode. When off, it is regulating the output voltage (see Section1.3.1).

  • Page 28: Earth Leakage Current

    Earth Fuse An earth fuse is present on the rear side of each NGPS and it is rated at 5 A, 500 V (F5AH500VAC). The blowing of this fuse generates a fault condition of the power unit and the fuse needs to be replaced in order to get rid of the fault condition before resetting the NGPS internal status register.

    NGPS 200-50 (i.e. the maximum power supply output voltage is 50V, see Table 1a: Standard NGPS models). By setting a current of 100A to the load, the output voltage would reach a value of 100V, which obviously is not feasible with this model. Indeed, once the power unit supplies 50A to the load, it has already reached the maximum output voltage condition.

    NGPS – User’s Manual Introduction The threshold value [°C] can be modified by experienced users. A reset fault operation needs to be executed on the status register of the NGPS before turning the output on again. DC-Link Undervoltage The NGPS is internally composed by a power AC-DC section cascaded with a DC-DC stage.
