THROUGH HOLE CURRENT
SENSE TRANSFORMERS
VDE Approved
Meets IEC950 insulation requirements
3750V
RMS primary to secondary
breakdown voltage
Frequency range 10kHz to 200kHz
Electrical Specifications @ 25°C — Operating Temperature -40°C to 130°C
NOTES:
1. These current sense transformers have a 1 turn primary winding, secondary
turns (Ns) as indicated in the table, and a 130°C insulation system.
2. The reference values are for unipolar operation, 50kHz, 40% duty factor, and
an estimated 55°C temperature rise.
3. The maximum useable peak sense current (I
PK
) depends on temperature rise
or core saturation, which should be evaluated for the operating conditions.
4. These Current Sense Transformers are recommended for switch mode
power supply applications, unipolar or bipolar, operating at frequencies from
10kHz to 200kHz.
5. The maximum recommended operating flux density (B
OP
) is 2000 gauss to
prevent saturation at an operating temperature of 105°C.
6. The core loss factor (K
CL
) is valid from 10kHz to 200kHz at 105°C.
7. The terminating resistor (R
T
) may be varied to adjust operating flux (B
OP
),
droop, or scale factor (K
VI
).
8. The scale factor (K
VI
) is proportional to the terminating resistor (R
T
) and is
equal to 1 volt/amp when R
T
=N
S
.
9. The secondary inductance (L
S
) is measured at 15kHz and .5V for PE-67050,
1V for PE-67100, 2V for PE-67200 and 3V for PE-67300.
10. To order RoHS compliant part, add the suffix “NL” to the part number (i.e.
PE-67050 becomes PE-67050NL).
