The TSU works under 1+! backup mode. Normally the two TSUs

output equalized current. When one TSU gets faulty, another TSU will

supply power to the transmission equipment and report alarms.

TCUTCU

TCU real-time monitors the temperature

in the cabinet. By controlling the power

distribution of the cabinet, it can prevent

the damage of over-high or over-low

temperature to the equipment and

components.

TCU controls the 220V AC input from

the external power supply, the +24V DC

output of the storage batteries

(excluding the power distribution of the

air-conditioner) and the power-on/off

commands for some boards according

to the temperature of the cabinet.

Temperature Adjustment SystemTemperature Adjustment System

The heat dissipation and heating under low temperature of

outdoor BTS3012A are accomplished by temperature adjustment

system. The temperature adjustment system has high reliability

performance and reports alarms when faults occur. The

temperature adjustment of BTS3012A is accomplished by the air-

conditioner or the heat exchanger.
