TRAFFIC LIGHTS

The illuminating devices created on a basis of light-emitting diodes of matrix are offered.
Quasi - monochromatic  uniform along the full length fluorescence increases distance of signal recognition by the driver.The absence of reflectors and color filter with special optical devices  is excluded occurrence of "phantom" effect (false impression about signal operation).

The absence in the design of gas-filled elements is increased stability of electro security and waterproof. 

The design of the traffic lights allows to install its on existing traffic light columns.

Circuit design gives the opportunity to connect traffic lights on crossroads for complex operation.
The economy of energy as compared with incandescent lamp more than 5 time. 

Three modifications of traffic lights  are produced: 

TL-20 (diameter of light blocks-20 cm);

TL-15 (diameter of light blocks-15 cm);

TL- 8 (diameter of light blocks-8 cm).

TL - 8 is installed on walkway and has the sound device, which give to pedestrian sound signal: 

  • Stop! Wait!
  • Attention! Crossing will soon open!
  • Attention! Crossing will soon close!
  • Crossing is open! May go!

INDICATOR BOARD OF EXCHANGE RATES "MARKET"

It is intended for exchange rate indication. The information is indicated on  seven-segment light indicator which causes the height of digits.

Data input and control is carried by: 

  • three buttons, arranged on the side face of board; 
  • the infrared remote control (distance between board and remote control up to 10m ); 
  • the personal computer with the  standard sequence  port  RS232. 

The board allows to storage the last input information at  switched OFF mode.

Four modification of boards are produced, which have got 3, 4, 6 and 10 demonstration lines with the  information of sell and  buy correspondingly: MARKET-3; MARKET-4; MARKET-6; MARKET-10, 

MARKET-6 and MARKET-10 are equipped by electronic clock and calendar (date and month). The electronic clock and calendar may be installed on other  modifications  too on the customer's request.
The amount of demonstration lines may be done by the  special order.

 

SPECIFICATIONS

AC supply voltage    200...240V
Sizes of digits of date and calendar  20/45mm
Height of exchange rate digits  20mm

REPEATERS FOR MOBILE COMMUNICATION SYSTEM RGSM-900 (ОUT)
 

 

It is intended for increasing of GSM mobile communication service zone in places with a low level.

Repeater’s using allows provide a reliable phone communication in places with impossible communication for some reason. To a category of such places are referred so-called, "shadow areas".

Repeater provides increasing of mobile communication range at line of sight of base station.

Repeater amplifies a signal and reduces risk of communication losses or interruption at the lowest signal level.

Advantages:
- decrease of a microwave irradiation of the subscriber at the cost of a power decreasing, demanded for reliable reception;
- increasing of accumulator work duration without recharging of a battery.

Delivery complete set:
      - transceiver module.....................1pc.;
      - antenna as "wave channel".........2pcs.;
      - connecting cables.
 

It is possible manufacturing of antennas with a spectral radiation (reception of three operators is provided) on the customer's request.

GSM BICONICAL ANTENNA

 

We offer small-sized broadband antenna for mobile communication, which operates on two GSM 900/1800 standard ranges.

It is a cylinder with 50 mm diameter and 120 mm height.

It operates both in composition of repeater for mobile communication and in composition of transmitter of the base station of operator’s mobile communication.

The antenna is easily at installation and does not demand adjustment.

Type of connector is on the customer’s order. 

 

SPECIFICATIONS 

Operating frequency range 880...960 MHz 1710...1870 MHz 
VSWR , no more than 1,41,6 
Gain factor 2,4  dB2,6  dB 
Input   impedance  50 Ohm 
Maximum  radiating power   20 W 
Weight, no more than 100g 
Polarization  linear vertical 
Directional pattern of antenna in horizontal  plane  circular 

It is possible to increase gain factor in twice at the expense of cylinder’s height increasing.

 THREE-COLOR ILLUMINATED INDICATOR BOARD

It is microprocessor software-programmable device with the display.The device consists of light-emitting elements blocks (LEEB), on which the advertising-information animations are indicated in GIF format .  

Each LEEB is matrix [16x16] from two-colored LED of red and green colors.The third color is yellow, which is deduced by simultaneous switching on of red and green light-emitting diodes.
Board is made from 3 rows and 7 columns of LEEB.  Number of rows and columns of LEEB can be changed on the customer's order.

  Information input on board is carried out by:

  • PC, compatible with IBM PC through three-strand cables, which has RS232 standard port. The special package of program operates in WINDOWS;
  • built in computer with connection of monitor to board, floppy drive and keyboard.

 The files with advertising - information messages are stored on non-volatile memory of the board in g*.gif format and is indicated on the board at it switching ON with cycling.

The current time which is corrected by PP is automatically indicated on the board, after each advertising-information message.
Software of the board allows to simulate operation of the board on the monitor and if necessary to enter changes without viewing on the board.

 SPECIFICATIONS

Supply voltage 190...250V
Power consumption of one LEEB 11W
Luminous intensity 0,9mcd
Diameter of LEE 10mm
Distance between elements centers by vertical and horizontal 15mm
Height of the rows at line realization225mm
LEEB sizes240x240mm
