Tech Note 1072 Detail

Power connector specifications for SPARK SLS (PS-2008) for extended data collection.

Affected Products:

PS-2008 SPARK Science Learning System

Problem/Symptom:
Alternative power sources for SPARK SLS.

PASCO Solution:

Any unregulated power source (battery pack, solar cell, or power adapter) can be connected via the DC power adapter port of the SPARK SLS as long as the input voltage is within the range of 5 to15 VDC. The recommended external voltage is 12 VDC. As the input voltage approaches the lower limits of this range, the rate of battery charging will diminish. Input voltages in excess of 15 VDC will damage the interface.

The power connector to the SPARK is a center-positive 4.75 mm (OD) x 1.7 mm (ID) barrel connector as shown below:
