3 1/2 digit LED, 20V

The DP-350 Series is an ultra-compact, highly reliable LED panel meter. This meter is ideal for applications requiring bright easy-to-read digits in a small package. The flexible window-mount packaging with optional bezel enables embedding within OEM equipment or traditional panel mounting. The simplicity of function, overvoltage protection, and low power consumption all contribute to the high reliability of this device.

Three input voltage ranges are offered: ±200mV, ±2VDC and ±20VDC. A 4 to 20mA current input adapter (DP-370) is also offered. Automatic polarity, overrange indication adjustable decimal point, and display HOLD are standard features. The DP-350 Series employs a dual slope integrating A/D converter, and operates from an internal 100mV reference via a precision DC-to-DC converter. Typical accuracy is ±0.1%.
