Current Sense Inductors & Transformers
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 or 4000VAC
• Meets VDE norms
• Optimum performance over designated current and
frequency range
• Competitive pricing due to high volume production
• Manufactured in an ISO 9001:2015 and
ISO 14001:2015 certified Talema facility
• Fully RoHS & REACH Compliant

:
Secondary inductance tested at 10KHz and 10mV for 1:50 through1:500
Prim./Sec. Ratios and 1KHz/10mV for Prim./Sec. ratio of 1:750
2) 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.
3) For Prim./Sec. Ratios of 1:50 through 1:500, the I
sec
value corresponds to a 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.
