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 and
reduce the abnormal behavior of the CoolSET. The diode can be a fast speed diode such as IN4148.
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 principle behind is to drain the high surge voltage from Live/Neutral to Ground without passing through
the sensitive components such as the primary controller, IC11.
