Features:
  • High efficiency
  • Short circuit proof and unlimited operation with full current in short circuit condition
  • voltage and current regulation with automatic and sharp transition; control mode indicated by LEDs
  • Voltage and current setting with 10-turn potentiometers with precision scale; the adjusting knob can be locked
  • 4½ digit DVM for voltage and current (for table-top models)
  • Sense terminals for the compensation of voltage drop on the load lines. The nominal voltage always refers to the output terminals
  • Parallel and series connection possible
  • Suitable for inductive and capacitive loads
  • for 700 W nominal power and higher, limitation of inrush current on switching on
  • Interlock loop to monitor the external load and internal loop as a standard for three phase units
  • Elapsed-hour meter as a standard for three phase units

Function:

The mains voltage is transformed to the appropriate level. On the secondary side of the transformer, a controlled rectifier with thyristors (phase cutting circuit) is installed. The rectified voltage charges a bank of capacitors of the intermediate circuit, from which it is given via a serial regulating transistor and a small LC-filter to the output. By switching-on the thyristors with a distinct delay after each zero-crossing of the sinusoidal voltage, the flow of energy is controlled in a way to have a defined voltage drop at the serial transistor (pre-regulation). The serial transistor defines the final stability of the output voltage (main regulation).

Design:

  • Up to 140 W nominal power ½19" table-top case
  • For 350 W nominal power or higher 19" table-top case
  • 19" Rack-adapters for mounting into a 19" rack are available as accessory
  • For 7 kW nominal power or higher 19" cabinet. Height depending on type. The side covers are detachable, the rear door is lockable.
  • All cabinets are equipped with fork-lift-compatible plinths and removable crane-eyes.
  • Single 19"- cabinets up to  38 HU are are easily transportable by fork-lift.
  • The cooling is carried out via built-in Fans, the output air is derived (type depending) to the rear side or via the top. For units of high output power water cooling can be made. 

Output:

  • Output isolation:
    The output is floating. Operating voltage with respect to earth: ±500 V, either the positive or the negative terminal may be connected to earth. For units equipped with the analogue programming: the "0V" of the analogue programming is connected to the positive output.
  • Output terminals:
    Output terminals are on the rear panel. Up to 20 A output current, 4 mm safety connectors are used. For current up to 300 A - clamps are fitted, for higher currents we use copper bars.

Technical Data:

  • Mains connection:
    up to 1400W nominal power:  230 V ±10% 47 Hz to 53 Hz
    for 2800W and 4200W:  400 V ±10% 47 Hz to 53 Hz, two-phase
    for 7000W and higher  400 V ±10% 47 Hz to 53 Hz, three-phase
 

  • Ambient temperature: 0°C to +40°C

Function:

The mains voltage is transformed to the appropriate level. On the secondary side of the transformer, a controlled rectifier with thyristors (phase cutting circuit) is installed. The rectified voltage is smoothed by a LC - filter.

Design:

  • Depending on Voltage and Power the units are built as single or double 19" cabinets of various height. The side covers are detachable, the rear door is lockable.
  • ll cabinets are equipped with fork-lift-compatible pliths and removable crane-eyes.
  • Single 19"- cabinets up to  37 HU are also suitable for transportation by fork-lift.
  • The cooling is carried out via built-in Fans, the output air is derived (type depending) to the rear side or via the top. 

Output:

  • Output isolation:
    The output is floating. Operating voltage with respect to earth: ±500 V, either the positive or the negative terminal may be connected to earth.
  • Output terminals:
    All output terminals are located at the rear side of the cabinet. For Output current up to 300A feed though terminals are equipped; for higher current, the output is made by copper bars.

Technical Data:

  • Mains connection:
     400 V ±10% 47 Hz to 53 Hz, three-phase

Function:

In principle, the rectified line voltage drives a square wave generator of variable frequency, whose AC voltage is transformed, rectified and filtered, producing the output voltage. For regulation, the square wave voltage is pulse width modulated. When fitted with the optional IEEE 488 interface, the NCN series become versatile programmable power supplies.

Design:

Output:

  • Output isolation:
    The output is floating. Either the positive or the negative pole may be connected to earth. Maximum isolation voltage: ±500 V

    (Not valid with the option analogue programming. If the floating function should remain, the floating analogue programming must be chosen).

     

  • Output terminals:
    Output terminals are 4mm safety connectors at the rear side of the unit. Units from 24 A nominal current on have binding posts.

Technical Data:

  • Mains connection: 
    Up to 2500 W nominal power 230 V ±10% 47 Hz to 63 Hz;
