Applications
Isolated current feed-back signal in Switch Mode Power Supplies Motor current load/overload Lighting Switch Controls Ultra-
sound current High resolution sonar current
Isolated bi-directional current sensor with full wave bridge rectifier
AS Series
Current Sensors are designed as a low cost method
of controlling, monitoring or measuring AC currents. The
sensors serve as feedback elements between the output and
pulse control circuitry providing accurate regulation of switch
mode power supplies.
Features
Fully encapsulated for optimal PC board mounting
Frequency range from 20kHz to 200kHz
Primary current rating to 15 Amps
Primary to secondary isolated to 2500 VAC
Meets VDE norms
Optimum performance over designated current and
frequency range
Competitive pricing due to high volume production
Manufactured in ISO-9001 approved facility

: Secondary inductance tested at 10kHz and 10mV.
This nominal termination resistance value will yield approximately 1.0V
of output for each amp of current in a single turn sense line. The output
Voltage/Ampere of these devices can be increased or decreased linearly
over a restricted temperature range by adjusting the terminating resis-
tance.
