Long Term Transmitter

PKI 2280Print

In every specific case it is difficult to select the most suitable transmitter for monitoring a room. Whether extended operation time, high output power or small dimensions are the main factors – at every time the operator has to make his own decision. But we have the right solution for all of these purposes. Every possible device for large transmitting ranges, high output powers and/or other features may be found in this catalogue. With the PKI 2280 we offer a battery operated transmitter with the main advantage of extended operation time with one single set of batteries only. The supplied set of different battery adapters enable a variety of operation times from 24 hours to a maximum of approx. 2100 hours. The output power of 1 mW allows transmission in ranges of several hundred meters within the UHF-radio band.
