of the panel meter's housing allows the module to be
suit high and low volume applications. The DPM 1AS-BL is intended to replace the DPM 1, DPM 1S, DPM 1-BL and
DPM 1S-BL in many applications, usually requiring only minor circuit modifications.
FEATURES
TYPICAL APPLICATIONS
• Precision Instrumentation Systems

• Panel-Mount Indication
• Low Power Voltage Measurement
ELECTRICAL SPECIFICATIONS
SAFETY
To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pins must not exceed
60Vdc. The user must ensure that the incorporation of the panel meter into the user’s equipment conforms to the
relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for Measuring, Control and
Laboratory Use).

* To ensure maximum accuracy, re-calibrate periodically.
** Operation of the meter beyond the maximum supply voltage rating may cause permanent damage to the meter.
*** An external series resistor is required above 5V, see Applications.
