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 30 Amps
• Primary to secondary isolated to 2500 VAC
• Meets VDE norms
• Optimum performance over designated current and
• Competitive pricing due to high volume production
• Manufactured in an ISO-9001:2000, TS-16949:2002
• Fully RoHS compliant
Applications
Isolated current feed-back signal in Switch Mode Power Supplies •
•

Prim./Sec. ratios and 1kHz/10mV for Prim./Sec. ratio of 1:750
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 resistance.
For Prim./Sec. Ratios of 1:50 through 1:500, the I
maximum primary current of 15 Amp-turns rms while the Isec value for the ratio of
1:750 corresponds to a max. primary current of 30 Amp-turns rms.
