Pyro Safety Module (PSM) HCEVSPF-1L

  • The breaking of this product is realized by pyrotechnic drug producing high pressure gas to cut off the conductor.
  • It can control the action by triggering signal and does not depend on the thermal effect of current.
  • Therefore, it can be broken reliably in the case of low multiple or even no current, the breaking time is less than 1ms;
  • When the short circuit current is large, it can also cut off the circuit quickly to limit the peak current;
  • The external or built-in control circuit can set flexible protection strategy according to the actual working conditions of the system.
