AEI editors review the latest testing products, equipment, and technologies used for various automotive applications from the industry's suppliers.

With the modified and extended KPS 004 starter and alternator test bench from Robert Bosch GmbH, powerful alternators and voltage regulators can be tested under conditions comparable to normal operation. The bench is designed to test alternators having a capacity up to 240 A/14 V in 12-V systems and up to 120 A/28 V in 24-V systems, as well as starters with output power up to 10 kW (13 hp). It is equipped with a new display technology; the measured data for rotational speeds, electrical currents, and tensions are indicated on easy-to-read digital measuring devices, which are protected against vibrations by a spring-mounted instrument panel. The KPS 004 also includes a continuously variable-speed adjustment for alternator drives with three-phase ac motor and frequency converter. According to the company, the technology is suitable for all starters and alternators available on the market.
