Over 30 years since we founded Karak in 1977, we have achieved solid growth in audio, video, security and PA (Public Address) system business. All of the outstanding performance that Karak has attained became to fruition through the trust and affection of customers and cooperative parties who expressed interest in Karak. We are expanding our line-up from low price analogue products to high technology digital products to meet various demands of the buyers in price and quality. We would like to draw your attention to such brand new products as PRODIGI (full digital OTL amplifier) and U-SOTEC (Network PA system) series, which can make you more competitive in the market. Karak is taking our first step into the next 30 year. We will exert ourselves to world audio and PA market to provide valuable audio an PA experience for world potential customers. Eventually we will be the one who create and give back more value to the world potential customers.

The new 9250/9251 amplifier generation unites all the features that make modern measurement data acquisition actually possible for the first time. Network-compatible, high-precision, user-friendly, smart and versatile: the combined system of amplifier module and bus controller can be integrated into any existing setup. The amplifier 9250 in conjuction with the fieldbus controller 9251 takes signals exactly to the point where they can be combined, monitored and linked efficiently to other data. The fieldbus interfaces give you flexibility, speed and perfect connections, and save you time, money and other resources when integrating your measurement setup with existing systems. Automatic sensor recognition due to burster TEDS lets you play absolutely safe, protecting you from setting incorrect parameters. The broad supply voltage range permits operation on standard power supplies used in switch gear cabinets.

Situations often occur in practice in which it is necessary to place a measuring amplifier immediately in the neighborhood of the sensor in order to be able to access a standard signal there. In this way, long distances to the evaluating electronics can be covered. This task can ideally be performed by the 9236 in-line measuring amplifier. With its high degree of protection (IP67) its singlechannel version can be integrated into the application even in the tough environment outside the switch gear cabinet. — Automatic production machinery — Laboratory measurements — Integration into customer‘s circuit boards — Field measurements Features: — Operates with up to 4 measuring channels — Voltage output 0 to ± 5 V / 0 to ±10 V — Protected against reverse connection and short-circuit — Also available as circuit board without housing — Simple configuration using DIP switch — High degree of protection up to IP67

In practice the requirement often arises to convert the measurement signals of a sensor into a standard signal in the simplest possible manner in the immediate proximity of the sensor. This permits trouble-free, low-loss transmission of measured values over longer distances to an instrument board or plant controls. Ideally suited for this purpose is the in-line measuring amplifier, which is inserted in between in the connection cable by means of plug contacts. Owing to its compact, robust design and low weight, it finds use in almost any application. Even movable locations subject to forces of acceleration, for example manipulators, present no problems. It is intended mainly for use of control cabinets in just about any location and is matched to a specific sensor. The aluminium housing is extremely sturdy and affords the greatest possible protection even in harsh environments.
