Product Description
The
AXC-102
is a power filter which provide high attenuation starting at extremely low frequencies
(30dB@20Hz). The device is designed for positive supply of 0 to 28 Volts and up to 20Amp load. The
output voltage tracks the DC input voltage with 0.6V drop (adjustable). Full performance is kept for input
ripple of up to 0.8 Volts p-p. Exceptional effort has been made to maintain low output impedance (less than
5m鈩?at audio frequencies). The
AXC
filters are designed to meet the most stringent noise requirements in
electronic equipment, laboratory power supplies, audio equipment, etc. Sense input provides a constant DC
voltage drop across the AXC102. A programmable current circuit breaker shuts down the device when the
current trough the module exceeds the rated current (programmable). The circuit breaker has two modes of
operation: Retriggerable and Non-retriggerable mode. A CBS (Circuit Breaker Status) indicates when the
device is in disconnected mode. A low level voltage (less than 1V), at SD (Shut Down) input, shuts down
the output voltage and the quiescent current drops below 2.5mA. This feature fits power management, as
well as battery power saving applications.
