The performance figures given in these specifications are applicable only
to equipment operating as an integral part of a TB9300 base station. These
performance figures are minimum figures, unless otherwise indicated, for
equipment operating at standard room temperature (+22 °C to +28 °C
[+71.6 °F to +82.4 °F]) and standard test voltages as follows:
■AC power management unit (PMU) - 120 VAC and 230 VAC

Note that the shaded areas denote frequencies that have reached end-of-life,
and whilst currently supported, are no longer available for the TB9300.
They are available for the TB9400, where B2 and B3 bands can be replaced
by the B1 band.
In Brazil, for K and L bands, the TB9300 is considered to be configured as
a base station with retransmission of receive frequencies.

a. User-programmable alarms can be set for low or high battery voltage, using the web interface. The alarms will be triggered
when the set voltage levels are reached. These limits are subject to the tolerances of the battery protection circuitry, as
stated in “Battery Protection (Fail-safe) Limits” above.
b. The user-programmable startup and shutdown limits allow for adjustable startup and shutdown voltages. Using the web
interface, these limits can be adjusted for different numbers of battery cells, or for the particular requirements of base station
operation. Once the limits are reached, the PMU will shutdown. These limits are subject to the tolerances of the battery
protection circuitry.
c. The battery protection limits are set in hardware at the factory and cannot be adjusted by the user. These limits will not be
reached under normal operation conditions, but are provided as “fail-safe” measures to protect the battery from deep
discharge.

1.4 Power and Current Consumption
The specifications in this section refer to the TB9300 base station fitted
with a PMU. Listed performance figures are typical.
The transmission measurements were taken when the base station was
transmitting at the stated RF output power, with all the front panel fans
running.
The standby measurements were taken when the base station was not
receiving or transmitting, with no front panel fans running.
All measurements were carried out with no load on the auxiliary power
supply.
