ZP-DM系列模块式电源浪涌保护器用于直流系统的保护，串联或者并联在直流供电电源与系统设备之间，防护外界（雷击、电磁辐射干扰等）或系统内部（系统拉合闸效应、感应及容性负载的启动和停止等）引起的浪涌脉冲及瞬间过电压对设备的损坏。
ZP-DM Series modular power surge protector for DC system protection, in series or in parallel between the DC power supply and the system equipment, door outside (lightning, electromagnetic radiation interference, etc.) or system internal (pull system closing effect, induction and load start and stop, etc.) caused by the surge impulse and transient over voltage of equipment damage.
