AX700
6 Duty / 1 Standby Amplifier Changeover Panel
Features

application schematic
auto amplifier changeover
AX700 is a platform for standby amplifier to take over failed duty unit in an automated changeover setup. Each unit
caters for 6 duty and 1 standby amplifier but expandable to larger setup with a single standby power pack.
It shall be used with amplifiers with auto fault sensing ( AFS ) such as PX series and whereas normal amplifiers are
used, Amperes AS4000 shall be installed at every duty unit. In such case, we recommend that Amperes AX3700 to
be used instead.
AX700 has protection features that only allow a single takeover to prevent overloading.
Cater for 6 duty and 1 standby amplifier
Expandable for 1 standby to serve more than 6 duty units
Overload protection by allowing only a single take over
Prioritized changeover - unit with higher number is preferred
for changeover

Compatible with most auto detection cards
