Precautions 2.1 Precautions Power Supply Input Polarity and Maximum Voltage Always ensure that the polarity and voltage of the external power connected VDD power input connector J8 is correct. Overvoltage or reverse-polarity power applied to this terminal can damage the evaluation module. 2.2 Operating Instructions List (See Figures 2−2 and 2−3.) Table 2−1. Typical Jumper Settings J1(FREQ) J2 (INT/EXT) J3 (SHUTDOWN) ON ON ON - Power supply 1) Ensure that all external power sources are set to OFF.
Operating Instructions List For example, consider the load to be a TEC element and the dc control voltage to be the output of a temperature control circuit. In this example, as temperature increases the output of the temperature control circuit increases. The TEC element should therefore be connected with the anode at PWM and the cathode at H/C to ensure that the TEC element cools when the temperature increases.
