短路保护

(Short Circuit

Discharge)

短路保护电流(Short circuit protection current) 见下面过流保护值配置表  ( See the configuration table of overcurrent protection value below)
短路保护延迟时间(Short circuit

protection delay time)

200 400 800 S
短路保护恢复(Short circuit protection recovery) 断开负载后延时 30s 恢复 。   ( Recover after 30S delay after disconnecting the load.)
短路说明:  短路电流小于最小值或高于最大值可能会造成短路保护失效,  短路电流超过3000A,  不保证有短路保 护,  也不建议做短路保护测试。

(Short-circuit description: The short-circuit current is less than the minimum value or higher than the maximum value,  which  may  cause  the  short-circuit  protection  to  fail,  and  the  short-circuit  current  exceeds  3000A, short-circuit protection is not guaranteed, and short-circuit protection testing is not recommended.)
