DPM 3AS-BL 3‰ Digit Backlit LCD Voltmeter Module PRODUCT DESCRIPTION The DPM 3AS-BL features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are user selectable. The DPM 3AS-BL features a negative rail generator which enables the meter to measure a signal referenced to its own power supply GND. LED backlighting ensures excellent readability under low light conditions. The design of the panel meter’s housing allows the module to beeasily snapped into a panel. The module’s low cost means it will suit high and low volume applications. The DPM 3AS-BL is intended to replace the DPM 3, DPM 3S, DPM 3-BL and DPM 3S-BL in many applications, usually requiring only minor circuit modifications. • 11mm Digit Height • 200mV d.c.
