Direct
current equipment level surge protectors are designed to protect up to 15A
of continuous DC load current. The MCG-12A-MCG-130A installs at or within
equipment such as DC servo mechanisms, fire alarm monitoring systems,
security system controls, telecom and datacom systems, etc. to provide
compact, heavy duty surge suppression.
The units clamp excess transient
over voltages in less than 5 nanoseconds and automatically reset -- ready
for the next transient. A green LED verifies that protection is present. The
DC protector's low-profile enclosure (4.95" X 2.85" X 1.25") uses
industrial-grade high-impact plastic and installs quickly via solder less
screw terminals.
Typical suppression at 50A using an 8/20 waveform ranges from 34V to
200V. Clamp voltages at 1mA peak is 18V 150V. Surge energy absorption (in
joules, 10/1000us) exceeds 455j. MCOV: 125% rated voltage.
The
DCP-90 is
designed to protect DC powered equipment, such as inverters and charge
controllers used in photovoltaic systems,
from damage caused by lightning. It utilizes high energy 40kA metal oxide
varistors and specialized fuses optimized to conduct transient current
without opening. The unit is dual redundant and has status indicators on the
front panel. Its small size makes it suitable for use in tight cabinets.
Rated at 160kA, the unit protects all modes. The DCP-90 is available in
various operating voltages so it can be customized to your application.
