Scope of application: SVP series fully automatic overvoltage and undervoltage protectors are suitable for users or loads with single-phase AC voltage of 230V, 50/60Hz and rated operating current of 63A and below. Function: The protector has functions such as overvoltage protection and undervoltage protection, low power consumption and long mechanical life. Main features: The main feature of the protector is that when there is an overvoltage or undervoltage or overcurrent in the line, the product can instantly cut off the power supply to protect the electrical equipment from damage; When the line voltage returns to normal, the protector can automatically work normally. Adjustable overvoltage protection value: Adjustable overvoltage recovery value; Adjustable overvoltage protection action time; Overcurrent protection; Adjustable overcurrent protection action time; Adjustable overcurrent protection action time. Use: Mainly used for overvoltage, undervoltage or overcurrent protection of residential distribution lines, or for the protection of single-phase power supply equipment. Overvoltage protection value range: 221V-300V-Off Adjustable (default 280V) Overvoltage recovery voltage mediation range: 220V-299V (default 250V) Overvoltage protection action time: 0.1s - 10s (default 0.1 seconds) Undervoltage protection value range: 219V-150V-Off Adjustable (default 160V) Overvoltage recovery voltage mediation range: undervoltage: 151V-220V (default 180V) Undervoltage protection action time: 0.1s - 10s (default 0.1 seconds) Overcurrent regulation range: 1-63A (default 63A) / 1-40A (default40a) Overcurrent action range: 0.1s -512S (default 5.0 seconds) Failure recovery time: 2S - 512S (default 60 seconds) Power-on delay time: 2s - 255s (default 2 seconds) Power consumption: 2W Electrical mechanical life: 4000 times Installation method: DIN rail
