DMS-3019X Series www.murata-ps.com Alternate Source for DP-650 Series, 3½ Digit LCD Display Digital Panel Voltmeters FEATURES OBSOLETE PRODUCT ■ Replaces DP-650, DP-652 and DP-654 meters ■ Connects directly to existing wiring ■ ±2V input range Contact Factory for Replacement Model ■ Low power consumption ■ Wider operating temperature range (0 to +60°C) ■ Rugged, epoxy-encapsulated plastic packages ■ Large (0.4˝/10.2mm) LCD displays DATEL’s DMS-3019X Series, 3½ Digit, LCD Display, Digital Panel Voltmeters provide DP-650 users with a superior-quality alternate source. The DMS-3019X Series input/ output connector is pin-compatible with nearly all DP-650 applications. Only minor sheetmetal modifications are needed to attain all the advantages offered by the DMS-3019X Series digital voltmeters. Provisions are also included for the addition of custom input-scaling resistors—a feature found only on DMS-3019X meters. Autozero calibration, autopolarity changeover and a factory-calibrated ultra-stable reference circuit are standard. A reliable, epoxyencapsulated DMS-30LCD digital voltmeter, with large (0.4˝/10.2mm) LCD digits, is used in all three models. All internal and external connections are 100% soldered—no elastomeric connectors are used. The DMS-3019X Series offers many noteworthy improvements over its competitors: wider operating temperature range, lower power consumption and higher input impedance, to name a few. And, most importantly, all DATEL digital panel meters are designed and manufactured in the USA!
