1 PRODUCTS FOR ELECTRICAL SUB-STATIONS UPS, DC-AC INVERTERS, BATTERY CHARGERS, DC-DC CONVERTERS, 1-PHASE TO 3-PHASE CONVERTERS GAMATRONIC ELECTRONIC INDUSTRIES LTD.

2 1. Introduction Founded in 1970, Gamatronic Electronic Industries Ltd. has spent the last 47 years developing and manufacturing products for a wide range of AC and DC power management applications. Our product line includes UPS systems, AC-to-DC rectifiers, battery chargers, voltage and frequency converters, and more. Gamatronic s headquarters and factory are located in Jerusalem, Israel. Business operations, including development, engineering, purchasing, manufacturing, sales, logistics, and customer service are handled in-house. Some assembly work is performed outside of our premises by leading Israeli subcontractors. Having developed hundreds of products, Gamatronic is an experienced designer of customizable power systems. Gamatronic prides itself on producing systems that meet the diverse needs of the ever-changing market, supported by our hard-earned reputation. Over the years, Gamatronic has gained extensive engineering experience in the power management sector, and we have many satisfied customers within Israel and throughout the world who can attest to our excellent service. Our list of past and present Israeli customers includes: Motorola, Israel Electric Corporation (IEC), Israel Railways, Israel Defence Forces, telecommunication companies such as Partner, Pelephone, Cellcom, and Hot Mobile, Siemens, Nokia/Alcatel, water desalinization corporations, hospitals, banks and more. Gamatronic has subsidiary corporations in the UK and China as well as local offices in South Africa and Brazil. Throughout the world Gamatronic has partners who help manage and support local activity. Our list of past and present customers abroad from the rail field includes: Bombardier, Korail (Korea Rail), KZA S.A (Polish rail), Irish Rail, China Rail and more.

3 2. Business Relationship Israel Electric Corporation (IEC) is one of Gamatronic s highest-volume customers. Their purchases include integrated UPS systems, rectifiers of various voltages (e.g. 220 Vdc, 48 Vdc.), DC-to-DC voltage converters, custom DC power supplies, and more. IEC utilizes a multi-stage approval process, checking that all Gamatronic products meet IEC s rigorous standards. After submitting a winning bid, these procedures cover compliance with specifications and design approval through delivery of a prototype for testing, volume production, and finally acceptance testing of each unit. Gamatronic's relationship with Israel Electric Corporation spans decades. Our history demonstrates that Gamatronic has the know-how and experience to rapidly move an idea from inception to a tested and approved solution, including all of the standard deliverables and any special requirements. Our familiarity with IEC s internal processes gives us an important advantage in projects for IEC. Gamatronic service technicians are authorized for entry to IEC s facilities, including those responsible for installation, maintenance, and repair. Our technicians undergo periodic training and continuing education at IEC. Their work is evaluated by IEC management over an extended period of time to ensure our customer s complete satisfaction. On the client side, IEC technicians are familiar with the operation of the abovementioned Gamatronic systems, leading to a shorter learning curve for all parties involved.

4 3. Gamatronic s Solution Gamatronic manufactures various types of systems needed by electrical substations, including: Uninterruptible Power Supplies 5KVA Power supplies 220 VDC, 30 A DC-to-DC converters 220vdc To 48vdc/60vdc 1-phase to 3-phase inverter, 120 kva 3.1 UPS 5 kva Gamatronic s UPS is a true online uninterruptable power system, designed according to IEC s specifications, and tested and approved by IEC. Hundreds of these units have been supplied to IEC. The unit is single-phase, with input and output of 230 Vac at 50 Hz. It employs Pulse Width Modulation (PWM) and is controlled by a 16-bit microprocessor. The design of the UPS s cabinet and the layout of its components were built as specified by the customer. Easy access to the terminals, including for the external battery, and for all maintenance activities, is provided through the front panel of the cabinet. The UPS is easy to operate; the controller includes an LCD screen on which input and output voltage, input (option) and output current, and system status information can be displayed. The controller maintains a log of the last 200 system events, including start-up, shutdown, and any system errors or alarms. The UPS can be connected to a computer via an RS232 link to view system status and measurements. The communications card provides an SNMP link to a local or remote computer, for viewing system status or power measurements, and enables notification of system alarms via .
