Impact Resistance
Test method: Close switch K1, open switch K2. Repeatedly switch K1 ON/OFF for 100 cycles (2S ON, 2S OFF). The test resistor should not become open circuit. (Refer to Figure 3).
Note: Capacitor C selection based on customer requirements; default C=10uF if not specified. Resistor R value selection based on the circuit, converted to internal resistance; resistor power rating 20W, power factor 0.8; for resistors below 10W, typically use 20W, 5.1K(5%).
