The ATS – 3A telephone set is intended for providing telephone connection at the field connection facilities (shelter, command vehicles, etc) in telephone channels with natural acoustic band.
The telephone set is suitable for connection to telephone exchanges with supply voltage of 46V to 60V using the double- or single-circuit cable line with max loop resistance of 1 kV.
The telephone can be used at -20°C to +40°C and relative humidity of 80 %.
The casing of the ATS – 3A telephone set is made of impact-resistant plastic. It consists of the cover and body, which together make up the casing to protect the telephone’s sub-assemblies from being damaged under the field conditions. In its shape, the telephone casing forms the microtelephone all the telephone components are located in.
