Low-Profile 1/16 DIN Case
Low Cost
The DP315 is an economical, 5-volt powered, 3-1/2 digit DC voltmeter in a compact 1/16 DIN case. The height of the panel cutout is only 22 mm (0.88"), and the depth behind the panel is only 72 mm (2.83"). Low cost, small size and low power consumption at 5 Vdc make the DP315 ideal for OEM and portable-instrument applications.
