Battery Eliminator (2–12V DC Variable Power Supply)

The Battery Eliminator (2–12V DC Variable Power Supply) is a compact and dependable laboratory instrument designed to provide a stable low-voltage DC output for educational and industrial applications. Manufactured by Micro Technologies, this unit eliminates the need for disposable batteries by supplying regulated DC voltages required for electronics experiments, circuit testing, and laboratory demonstrations.

Designed specifically for educational laboratories, the Battery Eliminator enables teachers, students, researchers, and technicians to perform practical experiments without the inconvenience of discharged or partially exhausted batteries. It provides a consistent power source that improves the accuracy and repeatability of experiments while reducing operating costs.

The unit delivers selectable DC output voltages of 2V, 4V, 6V, 8V, 10V, and 12V through an easy-to-operate rotary selector switch. A heavy-duty copper-wound transformer with high-quality laminated core minimizes power losses and ensures efficient operation. The integrated full-wave silicon bridge rectifier converts AC input into smooth DC output suitable for laboratory applications.

For enhanced safety, the Battery Eliminator incorporates a built-in fuse to protect against overloads and short circuits. A front-panel power indicator and output terminals provide convenient operation, while robust BTI-15 terminals ensure secure electrical connections.

The instrument is housed in a durable metal cabinet capable of withstanding regular laboratory use. Compact dimensions make it suitable for laboratory benches, demonstration tables, and training workstations.

Available in multiple current ratings, the Battery Eliminator can be selected according to application requirements:

• 1 Amp Output
• 2 Amp Output
• 3 Amp Output
• 5 Amp Output

The Battery Eliminator is widely used in engineering colleges, universities, schools, technical institutes, industrial training centers, electronics laboratories, physics laboratories, vocational education centers, repair workshops, and research laboratories.

Every Battery Eliminator manufactured by Micro Technologies undergoes rigorous quality inspection and performance testing to ensure reliable operation, electrical safety, and long service life.
