Batteryless telephone system with public address mode BLTS-1006
The System may operate from the power mains and in autonomous mode (without
connection to the power mains).
Energy produced by generator rotation is stored by high capacity condensers in-
tegrated in telephones and сommutator telephones.
The System may be connected to power mains 24 (18…36) V DC (if required).
The System is connected to AC power mains via the System PSUs – PS-103,
PS-103-20.
Signaling units are powered from external DC network 24 V or AC network,
50 (60) Hz, voltage 220 V.
In case of power failure, the System automatically switches to inductor power,
not interrupting current connection.
The System includes metal cabinet for installation on open deck, protecting equip-
ment against water.
