2. Add Y-capacitor (C2 and C3) in the Live and Neutral to ground even though it is a 2-pin input
3. Add negative pulse clamping diode, D11 to the Current sense resistor, R12:
Version 2.0
b. Spark Gap 1 and Spark Gap 2, Live / Neutral to GROUND:
The negative pulse clamping diode can reduce the negative pulse going into the CS pin of the CoolSET
The principle behind is to drain the high surge voltage from Live/Neutral to Ground without passing through the
reduce the abnormal behavior of the CoolSET
sensitive components such as the primary controller, IC11.
These 2 Spark Gaps can be used when the lightning surge requirement is >6KV.
230Vac input voltage application, the gap separation is around 5.5mm
115Vac input voltage application, the gap separation is around 3mm

. The diode can be a fast speed diode such as IN4148.
