MidNite Solar MNSPD-300-DC Surge Protector Device, 3-Wire, 300VDC, For Classic and Other Charge Controllers, Off-Grid Combiners and 120/240VAC Circuits
Protection for Classic and Other Charge Controllers, Off-Grid PV Combiners and 120/240VAC Circuits.
The MidNite Solar Surge Protective Device (MNSPD) is a Type 2 device per UL1449 rev3 and designed for indoor and outdoor 4X applications. Engineered for both AC and DC electric systems, it protects both transformer and transformer-less inverters without interfering with the GFP protection circuit, it provides protection to service panels, load centers, Classic and other charge controllers, off-grid PV combiners, 120/240 VAC circuits or where the SPD is directly connected to the electronic device requiring protection. Maximum protection will only be achieved if the SPD is properly installed. Please read the installation manual carefully and follow the instructions.
The MidNite Solar SPD is offered in four models and three different voltages to maximize the required protection level. Protection is achieved by reducing the clamping surge voltage to a safe voltage that your system can sustain without damaging any electronics in the system. By using the chart below, select the SPD's that provide the protection your system requires.
The MidNite Solar SPD voltage rating should be chosen according to the nominal voltage of the system. Do not install an SPD with Maximum Continuous Operating Voltage (MCOV) below the nominal voltage of the system; this will deteriorate the SPD and making it unavailable when you most need it.
NOTE: The DC SPD will work well on all DC circuits up to 300 volts as well as any 120/240 VAC circuits. The difference between the AC and DC SPD is the way the LED's are powered.
Size: 3.8"W x 4.4"L x 3.5"D
