1.4 Safety and ESD Notes
EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT!
Standard ESD precautions must be taken when handling electronic equipment. The
78M6610+PSU contains ESD protected interfaces.
Do not connect test equipment or external development boards directly to the
78M6610+PSU hardware. Damage to the 78M6610+PSU and external equipment will
occur due to the 78M6610+PSU’s “high side” reference topology. The
78M6610+PSU’s V3P3 supply rail (i.e., “high side”) is connected directly to Neutral
(Earth Ground) creating a ground reference disparity with any properly grounded
external equipment.
The board components and firmware settings are designed to operate with the following nominal AC electrical
ranges:
Voltage
Current Line Frequency
10–240 VAC 10mA–20A 46–64Hz
1.5 Testing the 78M6610+PSU Boards Prior to Shipping
Before every 78M6610+PSU Kit is shipped, the following procedures have been performed at the factory:
• Full Calibration – Precise energy source equipment is used to calibrate the current, voltage, and ambient
temperature for both the 16-pin and 24-pin daughter cards
• Accuracy Test – A “bench” level test ensures the energy accuracy is within ±0.5%.
