OPERATING VOLTAGE: Nominal DC operating voltage is 13.8VDC and the specifications are
given at this voltage. However, the minimum DC operating voltage is 11 Volts and the maximum DC
operating voltage is 15 Volts as measured at the VDC input connector. Reduced DC input voltage will
result in lower output power and efficiency.
EIA DUTY CYCLE: WITH NO EXTERNAL COOLING:
110 W Output (FM)  30% duty cycle
NOTE: Use of TPL Mobile Amplifiers above the recommended duty cycle or in repeater
applications is not recommended and voids the warranty.
