| Automatic Speed Barrier (SP-5029A) |
| It is the first automatic barrier using personified clutch instead of hand-operated clutch. The traditional clutch, in case of power failure, it is necessary to open the chassis and manually operate the clutch with a cranking bar; Patent technology • There is an intelligent limit device using microcomputer control technology, dispensing with the limit switch. When the beam rises to the vertical position or falls to the horizontal position, the system will automatically detect the signal and stop operation. World leading technology, patent technology • The chip combines unique scientific mechanical structure with high electronic technology, ensuring trouble-free operation of the engine in whatever circumstance so that the beam of the barrier rises and falls freely. • Intelligent obstacle-sensitive return device, so that the system will lift the beam in case of any obstacle while the beam is falling; and the system stops operation in case of any obstacle while the beam is rising, and gives alarm at the same time, further ensuring safety. Extended functions • Reserved ground sensor connection, ready to connect with the ground sensor to provide other relevant safety functions. • IC system connection, ready for any additional simple IC card reading system, simple parking lot charging system and other road toll collection system. • Special chip, which balances the rising or falling beam in a special mode, free from the trouble that most domestic tension springs are easy to break or loosen. Patent technology • Built-in controller, which is waterproof and ensures stable performance and long service life of the controller. Parameters: • Operating temperature of machine core: -40°C ~ +75°C • Electrical operating temperature: -25°C ~ +75°C • Rated voltage: 220V±10% • Rated power: 80W • Remote control distance 30M • Startup speed: 4S/6S 60HZ • Optional beam lengths: 1M-6M |
