Michael J. Coyle founds MCG Electronics in Bay Shore, NY. A graduate of New
York University, School of Engineering (BSEE), his subsequent engineering
activities at Sperry Gyroscope and Hazeltine centered on high power (10
megawatt) radar systems and high voltage systems (to 270kV) with specific
attention to pulse modulators.
Voltage Crowbars, devices that sense when a DC over-voltage occurs and
switches rapidly from an “open” to a virtual “short circuit,” are the first

any other combination of voltage or current before the metal oxide varistor
device is physically damaged, ruptured or cracked. Michael Coyle.

DCP-90 which 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.
