The PT120CF is a chassis-mount instrument potential transformer from the PT Series, designed to measure the voltage of 120 VAC systems with 5 Volt full scale A.C. voltmeters. Its 120V, 50/60Hz primary drives a 0-5V secondary, which suits OEM engineers and panel designers who need to read line voltage with low-voltage metering or monitoring electronics.
The drawing identifies it as a channel frame potential transformer. Windings are high accuracy (1%, marked 0-5V 1% ACC. on the secondary), and the series is VA rated for 0.020 VA. Primary leads are red and secondary leads are black, with leads brought out 6.0" minimum.
Overall dimensions are 1.25 in (32 mm) high, 1.10 in (28 mm) deep and 2.06 in (52 mm) wide. The drawing gives A 2.063" +/-.063", B 1.10" TYP, C 1.25" MAX and D 1.75" +/- .063", and a single 0.19 in (5 mm) mounting hole (.187" +/- 0.015 on the drawing). Ship weight is 3.4 oz on the spec sheet, with a shipping weight of 0.26 lbs (0.12 kg).
The PT120CF is listed as RoHS and REACH compliant. Where a printed-circuit-board version is preferred, the series also offers the PT120PC pin-mount model with the same 120V nominal line voltage.
Ideal For
- Measuring 120 VAC line voltage with 5 Volt full scale A.C. voltmeters
