Curtis Instruments recommends a 4-layer PCB with a dedicated ground plane, and thermal vias under the device to ensure efficient heat dissipation. A minimum of 1 oz copper thickness is recommended for optimal performance.
To ensure EMC, Curtis Instruments recommends using a shielded enclosure, keeping the device away from high-frequency sources, and using a common-mode choke on the input lines. Additionally, a 10nF capacitor between the input lines can help reduce EMI.
Curtis Instruments recommends a pi-filter configuration with a 10uF capacitor, a 10uH inductor, and a 10nF capacitor to reduce input ripple and noise.
Curtis Instruments recommends checking the input voltage, output voltage, and current sense resistors for any signs of damage or wear. Also, verify that the device is properly configured and that the input voltage is within the recommended range.
Curtis Instruments recommends using an external thermistor or thermocouple to monitor the device temperature. The 701PR-102 has a built-in thermal shutdown feature that will disable the device if the temperature exceeds 150°C.
