Battery Eliminator
Product Code : SCL-EAE-11164
Quick answer: A battery eliminator is a bench power unit that replaces dry cells as the low-voltage DC source in school circuit experiments. This one gives 0, 2, 4, 6, 8, 10 or 12 V DC from a rotary selector, up to 2 A, at positive and negative terminals, with an ON/OFF switch and a front-panel fuse. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
Dry cells run down during a practical, their voltage falls as they age, and a class set soon becomes expensive. A battery eliminator draws its energy from the mains and delivers a chosen low DC voltage at its terminals, so every group starts each lesson with the same supply. The 2 V steps make it easy to change the voltage in equal increments, which is what is needed for Ohm's law readings and for studying how lamp brightness depends on voltage.
- Place the unit on a dry, stable bench and keep it switched off while connecting the circuit.
- Set the rotary selector to the lowest voltage needed.
- Connect the circuit to the positive and negative terminals, observing polarity.
- Switch on and take readings, then step the voltage up as the experiment requires.
- Switch off before changing connections, and keep the load current below 2 A.
Key features
- Seven DC settings from 0 to 12 V in 2 V steps via a rotary selector.
- Maximum output current of 2 A, marked on the front panel.
- Clearly identified positive and negative output terminals.
- ON/OFF switch for safe connection and disconnection.
- Front-panel fuse position for protection.
