Detailed Product Description

• Quiescent Current: <0.22mA
• Working current: >100mA

• Size(LWH): 41x30x8mm
• Transmitting dista(m): 3000
• Frequency: 315MHz (optional between 260-440MHz)
  

Specifications:

• Transmitting module uses SAW stable frequency, small temperature excursion, which can still guarantee the stable performance in the environment of vibration and big temperature change.
• Transmitter module has an external extra reliable power magnifying circuit, which improves tremendously the transmitting power and efficiency, the transmitting distance reaches 2000m-4000m and it makes it possible to control in very far distance.
• Frequency error is generally within +/-75KHz, not like LC oscillating circui of which the error is around +/-500KHz, so that guarantee the reliability.
• Under the normal conditions, the quiescent current is almost zero.
• The transmitter module generally requires DC9V as operating voltage, DC12V will shot the magnifying tube, only could be used less than one second. If the voltage is less than DC9V, the transmitting power will be less and the transmitting distance will be shorter.
• Factory setting frequency is normally 315Mhz, the frequency can be adjusted from 260MHz to 433MHz in case of special requirement.
