Description

The DU Series are a re-engineered version of the UM series. They have a faster processor, providing faster and more accurate readings. These economical DPMs are application specific with header selectable full scale ranges, 0.56” red LED display or optional high-efficiency green or super bright red LEDs. Scaling is user selectable between -1999 to +1999. The power supply is a isolated, linear and also user selectable from 100 to 120 V AC or 200 to 240 V AC, 50/60 Hz. For greater flexibility, an optional auto sensing and isolated switching supply (AC/DC 12 to 24 V AC, 9 to 36 V DC) or a 24 V AC isolated linear power supply are available. These meters provide enough flexibility for most applications, ideal for OEM applications.

n.b. Special meter inputs and scaling can be factory modified.

  • An economical option is the dummy (non-functional) right hand side zero which allows the meter to display readings from –19990 to +19990 without going to the expense of a 4.5 digit meter. The apparent resolution with the dummy zero option would be 10 counts.
  • The DU-Series have a matching DIN case style that is complementary to the Lynx, Leopard and Tiger family of meters. DU-Meters are the OEM’s choice for economical switchboard and process indication. For economy, each model is dedicated to a specific application and designed for quick and easy installation
