Orbit International Corp. (NASDAQ:ORBT) today announced that its Power Group, through its Behlman Electronics subsidiary (“Behlman”), received three new orders with a combined value of over $645,000.

The first order, valued at approximately $234,500, is for a commercial power supply used by a major appliance manufacturer to help improve the accuracy of its product testing and demonstration. For over 20 years, Behlman’s power supply has been used by appliance manufacturers to test the performance of household appliances, such as refrigerators and freezers, clothes washers and dryers, dishwashers, electric ranges and microwave ovens. Deliveries have commenced and should continue through the third quarter of 2013.

The second order, valued at approximately $157,000, is for a special commercial power supply used to deliver AC signaling for a high speed railroad system. Behlman has been supplying this power unit to several customers in the rail transportation industry for over 15 years and this order is part of the latest high speed railroad extension project. Deliveries have commenced and should continue through the fourth quarter of 2013.

The third order, valued at approximately $254,000 is a follow-on order for a COTS power supply used to power the optics on a fire control system for United States Navy ships. Behlman has been supplying these power units for a number of years and anticipates additional awards for these units through 2016. Deliveries are expected to commence in the fourth quarter of 2013 and continue through the first quarter of 2014.

Orbit also announced that it entered into an Amendment to its Credit Agreement with its primary lender whereby the maturity date for the Company’s $6 million committed line of credit was extended to July 1, 2015.

Ron Storm, President of Behlman, commented, “Despite challenging economic conditions, Behlman’s business from its Commercial division remains strong with activity for both new and repeat orders for its products. Behlman continues to work with major OEMs developing power solutions for many commercial and military programs which should continue to provide many years of repeat business.”

Mitchell Binder, President and CEO of Orbit International, commented, “2013 has been a year of strong bookings for the Commercial division at our Power Group. Although bookings for our COTS division and our Electronics Group as a whole are sporadic due to budget uncertainty, our legacy programs remain intact and we have great confidence in the long-term prospects of our business. I am pleased to announce that our primary lender shares our confidence with a two-year extension to our credit agreement. Our strong financial position should enable us to take advantage of new opportunities in our marketplace.”
