SP 300
PRODUCT DESCRIPTION
The SP 300 features a 200mV d.c. measurement range with auto-zero and auto-polarity.
selectable. The SP 300 features a negative rail generator which enables the meter to measure a signal referenced to its
own power supply 0V. The bright red LED display ensures excellent readability under low light conditions. It can be
blanked in applications requiring low power operation. 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 and seal ensures splash proofing in many applications.
FEATURES
TYPICAL APPLICATIONS
• Precision Instrumentation Systems
• Power Supply Monitoring
• Test Boxes
• Panel-Mount Indication
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).
