SP400-BLUE Lascar

SP 400-BLUE 3 Digit Backlit LCD Voltmeter Module PRODUCT DESCRIPTION The SP 400-BLUE features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are user selectable. The SP 400-BLUE features a negative rail generator which enables the meter to measure a signal referenced to its own power supply GND. Blue LED backlighting ensures excellent readability under low light conditions. The module is easily fitted into the panel, using the fixing clip provided. The module s low cost means it will suit high and low volume applications. The design of the panel meter s housing ensures splash proofing using the supplied seal.

Unless otherwise noted, specifications apply at T =25C, V =5Vd.c. (f =48kHz) and are tested with the module configured for single ended A supply clock input mode. SAFETY To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the modules pins must not exceed 60Vdc. The user must ensure that the incorporation of the panel meter into the users equipment conforms to the relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for Measuring, Control and Laboratory Use).
