Features:
- Used to Drive Turbomolecular Pumps
- Mains Voltage Ranges, Selectable:100/120/220/240 V
- Mains Frequency: 50/60 Hz
The Leybold NT 151/361 Series Electronic Frequency Converters is used to drive the turbomolecular pumps TURBOVAC150, 360, 150 CSV, 360 CSV, 150 V, 360 V,151,
361, 151 C, 361 C.
The TURBOTRONIK NT 151/361 converts the single
phase mains voltage into a three-phase AC voltage for
driving the asynchronous motor of the connected turbomolecular pump.
The following operational states are indicated by LEDs: mains voltage applied (POWER, green), acceleration (ACCEL, yellow), normal (NORMAL, green), failure (FAIL, red).
A relay output is also available for the NORMAL signal.
After starting the pump will run up at maximum current.
This is indicated by the ACCEL LED.
Having reached approx. 80% of the nominal speed the
NORMAL LED comes on and the ACCEL LED goes off.
The motor current is continuously monitored and controlled. If the speed cannot be maintained even at the
maximum current due to external influences, for example
because of a greater gas supply, the speed will drop but
the pump will continue to operate.
When the speed drops below 150 Hz approx. the LED
FAIL on the converter lights up.
The outputs are short-circuit proof and protected against
no load conditions.
The TURBOTRONIK recognizes which pump is connected.
The connection line between TURBOTRONIK and TURBOVAC may be up to 100 m long.
The TURBOTRONIK is contained within a housing, and
can be used as a table top instrument or for installation
in a 19" rack. Operation is by means of the START and
STOP buttons on the front plate.
The NT 151/361 Leybold Electronic Frequency Converter may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
