Product Description

Radio Transmitter Amplifier Circuit Tower Crane Communication Anti Collision Japan








  • Import from Japan, the first apply amplifier circuit-FET,the most advanced function, the smallest size, the best price compared with similar products.
  • The transmiting power can be set by programing during1-18W. All technical standards meet European industry standards.
  • Specific frequency of digital transmission (220-238MHz), 96 half-duplex channels can be set by programing, never occur errors.
  • Applying to temperature compensatery circuit (TCVCXO),stability of the frequency is better than ± 1.5PPM.
  • Operating temperature range: -40C~+70C, adapt to harsh working environment! Good quality for industrial grade products,scanning function (multiple scanning modes are available).
  • The ND250A and ND886A and ND889A equip with this function.
  • The casing made from Aluminum-titanium alloy,tiny size, easy to install, good heat dissipation; perfect shielding design, good electromagnetic compatibility and strong anti-interference ability.
  • The "long-transmiting" protective function can be programmed to set the transmitter's longest time of continuous transmission in order to ensure security of system.
  • Reversal access protection of power supply, Power supply and antenna input port protection and more multi-protection functions.
  • Powerful software functions,all parameters can be set by programmed: Power,Frequency,Squelch degree, Channel selection, "Long- transmiting" time limit, Power saving.
  • Operating mode, Frequency response speciality, Squelch electrical level, Digital switching logic electrical level, detect whether frequency output signal squelch Multi-indicator light display the working state, such as Programming state, Data transmission and reception states, Losing lock state.
  • Ultra-low power dissipation, the ampere-meter is 50mA (lower power consumption in Power-saving mode and Sleep mode), and the emission current is S2.2A (15W) designed by with dual VCO.The transceiving conversing will be fast when run-up time of the transmitter is less than 5ms.
  • Be matched with MODEM with different type
