Technical characteristics
Current converter selective A9-1
Also, this device may be called: A91, A9-1, A-91, A 91, a9-1, a91, a9 1.
A9-1 head-current selective targets for measuring alternating current at fixed frequencies in rail connections railways.
Specifications A9-1:
Converters provide a measure of rms AC power rail connections in accordance with the data given in the table below:
| Frequency selection | Suppression of 50 Hz frequency and its harmonics 1 and 3 | Current measuring range | Measurement limits |
|
25 Hz 50 Hz 75 Hz |
50 dB - 50 dB |
from 0,05 to 30 A A | 0,3 A; 3 A; 30 A |
| 175 Hz | 20 dB | from 0,05 to 10 A A | 0,3 A; 3 A; 10 A |
|
420 Hz 480 Hz 580 Hz 720 Hz 780 Hz |
20 dB | from 0,02 A to 2 A | 0,2 A; 2 A |
Suppression of the frequency channel adjacent A9-1 - no less than 20 dB.
Maximum permissible error of measurement of the RMS value of the AC power code sequence in a track circuit:
- At frequencies of 25 Hz and a selection of 50 Hz - no more than ±(5% +2 ed.ml.r. Ix)
- The remaining fixed frequencies - no more than ±(10% + 2 ed.ml.r. Ix), where Ix - measured amperage, ed.ml.r. - LSB unit.
Signals track circuit frequency of 25 Hz or 50 Hz amplitude modulation may be a pulse duration modulating at least 100 ms.
Signals track circuits of fixed frequencies 420 Hz, 480 Hz, 580 Hz, 720 Hz, 780 Hz may have amplitude (tonal) modulation with frequency modulation signal 8 Hz or 12 Hz.
Maximum permissible additional measurement error of rms AC current at the extreme frequencies bandwidth converter A9-1:
- At frequencies of 420 Hz selection, 480 Hz, 580 Hz, 720 Hz, 780 Hz - not more than 1.5% of the basic error limit;
- The remaining fixed frequencies - no more than 0,5% of the basic error limit.
Maximum permissible additional error measurements at ambient temperature changes from normal conditions to the limit values in the operating temperature range:
- Selection at fixed frequencies of 25 Hz and 50 Hz - not more than 0,5% of the maximum permissible basic error for every 10° C;
- The remaining fixed frequencies - no more than 0,3% of the maximum permissible basic error for every 10° C.
A9-1 converter provides an indication of the value of the input AC signal, set a limit of measurement, frequency selection, independent power supply voltage (2-3 from when the device) and its output values (if battery discharge) for the lower limit.
The device provides LED indication of the presence of modulation of the input signal.
Response time - no more than 10 seconds.
The converter has a backlit scale.
A9-1 stores the electrical parameters in the normal range after exposure to its input 30 for a signal is not greater than 300 A.
Setup time converters - no more than 4 seconds.
Mains voltage - 220±22 V.
Supply frequency - 50 Hz±1.
Independent power supply voltage converter - from 3 V to 4,8 V.
Current consumption from the battery - no more than 50 mA.
MTBF A9-1 - at least 30000 hours.
Gamma-percent life - not less than 20000 hours.
Confidence level - 0,9.
Unit Dimensions -190×90×45 mm.
Weight converter - no more than 0,7 kg.
Operating conditions A9-1:
Normal:
- Ambient temperature - (20±5)° C;

Description of the instruments taken from the technical documentation or technical literature. Most pictures of products made directly by our experts prior to shipment of goods. In the description of the device provided the main technical characteristics of the instrument: nominal measuring range, accuracy class, scale, supply voltage, size (size), weight. If the site you see the discrepancy device name (model) specifications, photo or documents attached - let us know - you will get a useful gift with-selling device.
While the need to clarify the overall weight and size or the size of the individual meter you can in our service center. If you need our engineers will help you choose the most complete analog or a suitable replacement for the device you are interested. All counterparts and replacement will be tested in one of our laboratories with the full compliance to your requirements.
In the technical documentation for each device or product, information is provided on the list and amount of precious metals content. The documentation gives the exact weight in grams of precious metals: Au gold, palladium Pd, platinum Pt, silver Ag, tantalum Ta and other platinum group metals (PGM) per unit item. These precious metals are found in nature in very limited quantities and therefore have such a high price.
On our website you can familiarize yourself with the technical characteristics of devices and obtain information on the content of precious metals in devices and radio components manufactured in the USSR. We draw your attention to the fact that often the actual content of precious metals differs by 10-25% from the reference one in a smaller direction! The price of precious metals will depend on their value and mass in grams.
All text and graphic information on the site is informative.

Check with the sales department for more information.
If you can make repairs to the device yourself, our engineers can provide you with a complete set of necessary technical documentation: circuit diagram TO, ER, FD, PS. We also have an extensive database of technical and metrological documents: technical specifications (TS), the terms of reference (TOR), GOST (DSTU), the industry standard (OST) test procedure, the method of certification, verification scheme for more than 3,500 types of measuring equipment from the manufacturer this equipment. From the site you can download all the necessary software (the software driver) is required for the product purchased.
We carries out repairs and maintenance of measuring equipment in more than 75 different factories of the former Soviet Union and CIS.
