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).
TYPICAL APPLICATIONS
• Precision Instrumentation Systems
• Power Supply Monitoring
• Test Boxes
• Panel-Mount Indication
• Low Power Voltage Measurement
DPM 750S-BL
3½ Digit Backlit LCD Voltmeter Module
The DPM 750S-BL features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are
user selectable.
LED backlighting ensures excellent readability under low light conditions. The module's
The meter features a negative rail generator which enables the meter to measure a signal referenced to
its own power supply GND. A low drift bandgap reference circuit ensures accurate readings over a wide temperature
range.
low cost means it will
suit high and low volume applications. This module is supplied with a plastic mounting bezel. A waterproof seal to
IP67 / NEMA 4X is achievable, using the optional BEZ 700-IP bezel.
* To ensure maximum accuracy, re-calibrate periodically.
** An external series resistor is required above 5V, see Applications.
*** This specification linearly derates to 30mA @ 50°C.
