The Beta D-50 Tester/Analyzer is a self contained unit for discharge capacity testing of rechargeable batteries. It has been designed to accurately test and guarantee the emergency capacity of sealed or vented lead-acid or nickel-cadmium batteries.
The Beta D-50 enables testing of a battery's capacity by loading it with a constant current of max 50 amperes (usually set to 80-100% of the battery's capacity rating) during a fixed period of time (usually 60 minutes). The D-50 analyzes the discharge characteristics and passes or fails the battery depending on the battery's ability to maintain a specified minimum voltage (cutoff voltage) for the duration of the test. The unit has pass/fail indicators as well as displays for discharge current, cutoff voltage, battery voltage, and test time.
The flexibility of test parameters of the Beta D-50 makes it usable for a wide variety of batteries and voltages. The unit accurately tests lead-acid batteries of 12 or 24 volts, as well as nickel-cadmium batteries of a single cell to 24 volts.
The use of solid state circuits in the Beta D-50 has kept its weight to a mere 30 lbs. (14 kg). Consequently the unit is easy to move around to accommodate flexibility in the work environment.
