Surge Protection You Can Count
On!
MidNite Solar Surge Protection
Devices (SPD) are Type 2 device per UL1449 rev3, NEC 2011 Article 285 designed
for indoor and outdoor applications. Engineered for both AC and DC
electrical systems they provide protection to service panels, load centers and
electronic devices that are directly connected to a MidNite Surge Protection
Device.

With lightning you only get
one chance. so get the best!.
The SPD is offered in four
different voltages to maximize the required protection level. Protection is
achieved by reducing the clamping voltage to a safe level that your system can
sustain without damaging any electronics in the system. The MidNite SPD are
designed to clamp a 115,000 amp surge! Blue LED’s provide visual indication of
operation from a distance.
