Battery Eliminator 12 Volt
Battery Eliminator 12 Volt (Product Code: SCL-416/105) is a mains-powered lab power supply unit used to replace dry cells in school and college electricity experiments. A rotary switch selects outputs from 2 V to 12 V DC in 2 V steps, and the input is selectable for 110–220 V AC. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the 12 V Battery Eliminator Used For?
The eliminator powers low-voltage DC circuits in place of cells, such as an Ohm's law experiment kit, resistance and meter bridge circuits, electromagnets, small motors and bulb circuits. Stepped outputs of 2, 4, 6, 8, 10 and 12 V let teachers start a circuit at a low setting and raise it one step at a time while students record readings.
Unlike cells, a mains unit does not run down during a long practical, which keeps readings consistent across a lesson. Set the input selection to match the local mains before switching on, turn the rotary switch to the lowest output before connecting a circuit, and use the colour-coded sockets to keep polarity correct. The stackable housings save bench space in storage.
What to Specify When Ordering
- Mains input setting required: 110 V or 220 V AC
- Number of units, for example one per bench or student group
- Connecting leads, rheostats or meters needed with the units

Frequently Asked Questions
What output voltages does the Battery Eliminator 12 Volt give?
The Battery Eliminator 12 Volt (SCL-416/105) gives 2 V to 12 V DC in steps of 2 V, selected with a rotary switch that has positive click stops. That covers 2, 4, 6, 8, 10 and 12 V settings for school electricity experiments.
What mains input does the Battery Eliminator 12 Volt need?
The Battery Eliminator 12 Volt accepts a selectable 110–220 V AC input at 50–60 Hz, and its primary side is protected by a 0.5 A fuse. Always set the input selection to match the local mains supply before switching the unit on.
Is the output of this Battery Eliminator regulated?
The listing for the Battery Eliminator 12 Volt describes double-wound transformers with bridge rectifiers but does not state voltage regulation or smoothing. If your experiment needs a regulated or smoothed DC output, ask us through the ScienceLab contact page before ordering.
What safety features does the Battery Eliminator 12 Volt have?
The Battery Eliminator 12 Volt has colour-coded safety sockets for its outputs, a separate safety socket for earthing, a 0.5 A primary fuse and a rigid ABS housing. The housings are stackable and stand on ergonomic feet, keeping benches tidy.
Who supplies the Battery Eliminator 12 Volt?
The Battery Eliminator 12 Volt is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. Schools, colleges, dealers and importers in India and international markets can request it alongside leads, rheostats and other electricity apparatus.
Is a calibration certificate available for the Battery Eliminator 12 Volt?
Calibration-certificate availability for the Battery Eliminator 12 Volt should be discussed with us before ordering. Mention the requirement in your enquiry so the quotation can state clearly what documentation, if any, accompanies the unit.
