BOLTEK

The Boltek LD-250 Lightning Detector puts a live lightning map on your laptop or desktop computer. Within milliseconds of a lightning strike the detector beeps and your computer displays the strike location. The LD-250's direction-finding antenna measures lightning strike direction while the LD-250's receiver estimates distance from received signal strength. Advanced signal processing in software improves distance accuracy, reducing the effects of strike-to-strike variations in strike energy.
The LD-250 can warn of both close and severe thunderstorms. If a storm is detected closer than a preset distance or the strike rate exceeds a preset limit, the LD-250 sounds its internal alarm and activates the computers alarm tone or WAV file notification. Both the Close Storm and Severe Storm alarm statuses are indicated on the LD-250's front panel.
Strike rates, both Close Strikes / Minute and Total Strikes / Minute are shown for the previous hour on the Strike Rate Trend Graph letting you easily see if storms are increasing in severity or dying off.
Three display ranges, 100, 200 and 300 miles (160, 320 and 480 km) allow you to zoom into the region of interest. Zoom out to the maximum range of 300 miles (600 miles across) or zoom in to 100 miles to see only the nearby storms.
LD-250 lightning data is live! Your computer beeps and displays the strike within milliseconds of the strike happening! With the LD-250 Lightning Detector you are actually detecting the lightning strikes themselves. There are no on-line or recurring charges of any kind.
LD-250-(220V) Lightning Detector Includes LD-250 Receiver, Antenna, 15 meters of Antenna Cable, 220VAC Power Supply, 12VDC Automobile Power Cord, USB Cable, RS232 Cable, GPS Cable, Windows Software, and Manual.

BOLTEK LD-350 LIGHTNING DETECTOR

The Boltek LD-350 Lightning Detector puts a live lightning map on your laptop or desktop computer. Within milliseconds of a lightning strike the detector beeps and your computer displays the strike location. The LD-350's direction-finding antenna measures lightning strike direction while the LD-350's receiver estimates distance from received signal strength. Advanced signal processing in software improves distance accuracy, reducing the effects of strike-to-strike variations in strike energy.

BOLTEK RLO-10 RELAY OUTPUT MODULE

The RLO-10 Relay Output Module provides three solid-state relay outputs for interfacing external devices to the LD-250 or LD-350 alarms and strike indicators. External devices such as PLC inputs or auxilliary indicators can be activated when the LD-250 or LD-350 alarm activates.

The Close Storm Alarm output contacts will close for one minute each time a strike is detected closer than 25 miles. Constant close lightning activity will hold the contact closed. The contact will open again when no close strikes have been detected for one minute.
The Severe Storm Alarm output contacts will close if the strike rate rises above 300 strikes/minute. Once the strike rate falls below 300 strikes/minute the contacts will open.
The Strike output contacts will close for 200ms every time a strike is detected.
