- 120V, 50/60Hz primary with 0-5V secondary for 5 Volt full scale A.C. voltmeters
- P.C. board pin mount with .025 square pins
- High accuracy windings (1%)
- VA rated for 0.020 VA
- Compact 1.40 in H x 1.08 in D x 1.03 in W footprint
- RoHS and REACH compliant
The PT120PC is a printed-circuit-board mount instrument potential transformer from the PT Series. It is designed to measure the voltage of 120 VAC systems with 5 Volt full scale A.C. voltmeters, taking a 120V, 50/60Hz primary down to a 0-5V secondary, and suits OEM engineers building line-voltage sensing directly onto a circuit board.
Windings are high accuracy (1%), with the drawing marking the secondary 0-5V 1.0% ACC., and the series is VA rated for 0.020 VA. Instead of flying leads, the PT120PC uses .025 square pins for P.C. board pin mounting; the drawing shows the primary on pins 1 and 5 and the secondary on pins 6 and 10.
Overall dimensions are 1.40 in (36 mm) high, 1.08 in (27 mm) deep and 1.03 in (26 mm) wide, and no chassis mounting hole is used (n/a). Ship weight is listed as 2.1 oz on the spec sheet and 0.15 lbs (0.07 kg) as shipping weight; the drawing titles the part a PC mount potential TX.
The PT120PC is listed as RoHS and REACH compliant. A chassis-mount version with the same 120V nominal line voltage is available as the PT120CF.
Ideal For
- On-board 120 VAC line voltage sensing
- Measuring 120 VAC with 5 Volt full scale A.C. voltmeters
- PC board instrumentation designs
