Cometek Battery Eliminator 0–12V 2 Amp Non-IC Regulated | Transformer-Based Step Voltage DC Power Supply

• Power : 0–12V 
• Amp : 2 Amp

Features

• Pure Copper Isolation Winding: Houses a premium step-down transformer that provides full galvanic isolation from mains AC voltage, ensuring supreme user safety during school labs.
• Rotary Step Voltage Selector: Heavy duty indexing selector switch guarantees solid, click-into-place mechanical lockouts over each voltage increment, preventing accidental shifts.
• Ruggedized Metal Housing: Encased in a powder-coated, ventilated steel enclosure that rapidly dissipates operational heat while shielding internal components from accidental impacts.
• Built-In Circuit Protection: Safeguarded by an inline secondary overload fuse setup that instantly cuts off current to prevent internal coil damage during accidental short circuits on the bench.

Applications

• Electromagnetism Induction Workloads: Supplies a constant 2 Ampere current pool to activate primary solenoids, horseshoe electromagnets, and magnetic field mapping coils.
• Analog Galvanometer Calibration: Provides smooth, low-noise DC electricity to calculate half-deflection and full-scale sensitivities on sensitive analog instrumentation.
• Basic Series and Parallel Studies: Acts as a centralized, risk-free voltage source to demonstrate voltage distribution across resistor networks, breadboards, and mini lightbulb sockets.
• Introductory Water Electrolysis: Delivers sustained low voltage DC energy through Hoffman apparatus platinum electrodes to cleanly separate water molecules into hydrogen and oxygen gases.
