QP2000 Series Power Amplifiers with
Auto Fault Sensor ( AFS )

QP2125 / 2250 / 2375 / 2500

Amperes Power amplifier with AFS - QP2500

QP2000 Series of amplifiers with auto fault sensing and in built fault changeover relay are available in various power ratings of 125W ( QP2125 ), 250W ( QP2250 ), 375W ( QP2375 ) and 500W ( QP2500 ).  They had been running for more than decade, powering many installations dutifully.

​

The distinct features are the auto fault sensor ( AFS ) and standby changeover relay. It self detect its amplifier circuitry and would initiate relay changeover for standby unit to take over its duty. QP2000 also has RS485 port which allows remote monitoring and controls directly from PC ( via UART converter or through iPX5500 network comm box ).
