Current Limitation Block for Emergency Notification and Selective Calling System SUBR-1P

Block of current limitation (BOT) is a functionally complete unit and is used as part of the complex of emergency notification and selective call of miners SUBR-1P. BOT is used to ensure intrinsically safe current level in each of the antenna cores. Current limiting unit provides division of the output current into a set of independent currents (50 pcs), flowing in the multi-core antenna cable of the Complex and limits the value of these currents, as well as the voltage on each of the antenna cable cores relative to the ground at the intrinsically safe level.

The current limiting unit may be used only in a set with a transmitter (PRD), TIS 6.4.0.00.000-01.
