Material: Main body: FR-4 flame-retardant PCB board (high-temperature resistant, corrosion-resistant) Shell: ABS engineering plastic (conforming to CPC E 94V-0 flame retardant standard); Electrical components: Surface mount resistors, capacitors, relays (switches with a lifespan of ≥ 100,000 times)
Technical specifications: Delay time of 3 to 5 minutes (to prevent frequent starts); Flame retardant grade CPC E 94V-0 (maximum flame resistance grade); Protection grade IP44 (Splash-proof, suitable for indoor humid environments)
Note: Before installation, disconnect the power supply of the device and wait 5 minutes until the capacitor discharges to avoid the risk of electric shock; Compare the wiring ports of the new and old control boards to ensure that the wiring sequence is consistent
