The DPF53 is a low-cost 31⁄2 digit dc
voltmeter with a full-size 14.2 mm
(0.56") LED, yet housed in a small
3
⁄64 DIN case with a 24 x 72 mm
bezel. The case fits into a standard
3
⁄64 DIN cutout, 22.2 x 68 mm
(0.87 x 2.68"), and requires a depth
of less than 120 mm (4.72") behind
the panel, including the standard
plug-in screw-clamp connectors.
