Designed to provide primary high capacity industrial surge protection at main service entrance locations, the DSP-M range gives ten-mode protection with a maximum surge handling capacity of 150kA or 180kA per phase. With built in redundant full varistor networks, the Sollatek DSP-M series ensure your premises are never unprotected. Visual warning or remote warning alerts the operator of the failure of one varistor network while the redundant unit keeps protecting the site thus ensuring your equipment is always protected, even after a direct strike. For even greater levels of protection, Silicon Avalanche Diode versions are available (DSP-150-SD) incorporating both SAD and MOV technology allowing for a lower limiting voltage; the worst-case voltage that will get through to the protected equipment. Remote monitoring is enabled by means of the unit’s normally-closed remote indication contacts. The unit is IP66 rated and UL 1449 approved.

* For even greater levels of protection, Silicon Avalanche Diode (SAD) versions are available incorporating both SAD and MOV technology. The SAD option allows for a lower limiting voltage; the worst-case voltage that will get through to the protected equipment.
