LOW VOLTAGE POWER SUPPLIES - NTN Series: Double stabilization with thyristor pre-control and linear control


Series NTN from 6,5 V to 350 V / 35 W to 100 kW

The mains voltage is transformed to the appropriate level. On the secondary side of the transformer is a thyristor controlled rectifier stage (phase cutting circuit), the output of which is used to charge a capacitor bank. This capacitor bank is also connected to the final series regulating transistor output stage. By controlling the conduction angle of the thyristors after each zero-crossing of the sinusoidal voltage, the flow of energy is regulated in such a way as to have a defined voltage drop across the final series transistor stage (pre-regulation). The performance of the final series transistor stage defines the final stability of the output voltage (main regulation).


FEATURES:

- Simple construction

- Short circuit proof and unlimited operation with full current in short circuit condition

- Voltage and current regulation with automatic and sharp transition; control modes indicated by LEDs

- Voltage and current setting via 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 also for inductive and capacitive loads

- Safety interlock loop and internal interlock is standard on three-phase units

- Elapsed-hour meter as a standard on three-phase units

SPECIAL FEATURES

Double stabilization with thyristor pre-regulation and linear regulation

Potential-free output voltage


DESIGN:

- Up to 140W nominal power ½19“ table-top case

- For 350W nominal power or higher 19“ table-top case

- 19“ Rack-adapters for mounting into a 19“ rack are available as accessory

- For 7kW nominal power or higher 19“ cabinet. Height depending on type. The side covers are detachable and the rear door is lockable.

- All cabinets are equipped with fork-lift-compatible plinths and removable crane-eyes.

- Single cabinets up to 38U are easily transportable by fork- lift.

- Cooling is carried out via convection or built-in fans, with the air being exhausted (depending upon type) either via the rear or the top. For high power units water cooling can also be used.


OUTPUT:

- Output isolation: The output is floating, maximum operating voltage with respect to earth: ±500V. Either the positive or the negative terminal may be connected to earth. For units equipped with the analog programming: the „0V“ of the analog programming is connected to the positive output.

- Output terminals: Up to 20A output current, 4mm safety connectors are used on the rear side. For currents up to 300A - clamps are fitted whilst for higher currents we use copper bars.


TECHNICAL DATA:

- Mains connection:

>> Up to 1400W nominal power: 230V ±10% 47Hz to 53Hz

>> For 2800W and higher: 400V ±10% 47Hz to 53Hz; two-phase

>> For 7000W and higher: 400V ±10% 47Hz to 53Hz; three-phase

- Ambient temperature: 0°C to +40°C


The following data applies for voltage and current regulation, and refers to the rated value (unless otherwise stated):

- Setting range: from approx. 0,1% to 100%

- Setting resolution: ±1 x 10^-4

- Residual ripple (0 - 10MHz): <1 x 10-4pp + 10mVpp

- Recovery time:

Voltage control: <50μs for load changes from 10% to 100% or from 100% to 10%.

Current control: <500ms for load changes causing an output change of less than 10% of the rated voltage.

Units with output voltage >65V, will switch off for a short time at high and fast load changes.

- Setting time at nominal load: 100ms to 500ms for changes of the output voltage from 10% to 90% or 90% to 10%

- Discharge time constant for output without load: approx. 2sec. to 60sec., depending on type

- Deviation:

For ±10% mains voltage variation: <± 1 x 10-5

For no load / full load: <2 x 10-4

Over 8 hours under constant conditions: <±1 x 10-4

- Within the temperature range: <±1 x 10-4/K


POSSIBLE OPTIONS:

- Coarse/fine-potentiometers (99% / 1%) for more accurate adjustment of voltage and / or current

- Analog programming (The positive output has to be earthed)

- Analog programming, floating

- Computer interfaces - IEEE 488, RS 232, RS 422, Profibus DP, USB, LAN (more on request)

- Roller blades for cabinet units

- Higher stability

- Power limitation
