PX2000 SERIES [ POWER AMPLIFIERS WITH AFS ]

________________________________________________________________________________________

VARIANTS :
PX2100 | 120W 100V
PX2200 | 240W 100V
PX2300 | 360W 100V
PX2400 | 480W 100V
PX2200

INTRODUCTION

PX series of power amplifiers are equipped with AFS (Auto Fault Sensor) which generate pilot tones internally and automatically diagnose and detect any faulty condition that may occur at the output end. Pilot tones are generated at intervals to avoid straining the power packs, and this shall prolong the life span of the units.

 

FEATURES

TICK Incorporating Auto Fault Sensing (AFS) circuitry for self monitoring of its output
TICK Pilot tone switchable for normal operation without AFS
TICK Interval PT generation to avoid continuous loading of the amplifier
TICK Thermal protection by muting input signal (typically 85º at heat sink)
TICK Temperature dependent dual speed cooling fan
TICK Manual reset circuit breaker for AC mains and DC input
TICK Balanced input signal with gain control and selectable grounding option
TICK AC and DC operation for uniterrupted operation during power failure
