ZZZ-Transtector DCPM Indoor DIN-Rail DC Surge Protectors (SPDs)

Transtector DCPM Indoor DIN-Rail DC Surge Protectors (SPDs) are DIN-rail-style SPDs that use Metal Oxide Varistor (MOV) or Silicon Avalanche Suppression Diode (SASD) technology to protect critical equipment that operates on a 7VDC to 70VDC electrical service. This Transtector DIN-rail DC SPD series provides effective protection against electrical transients generated by lightning and internal switching events. The DCPM Indoor DIN-rail series supports long-term system reliability by safely shunting high amounts of transient energy while maintaining a very low clamping voltage.
