SP 200
3? Digit Backlit LCD Voltmeter Module
PRODUCT DESCRIPTION
The SP 200 features a 200mV d.c. measurement range with auto-zero and auto-polarity. Decimal points are user
selectable. The SP 200 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 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.
