The CTEK PRO120 gives professional workshops precise control during all types of diagnostics, updating, and repair work. In power supply mode, it delivers selectable output voltages in 0.1V increments from 12.6V to 14.8V to match manufacturers' minimum service specifications exactly, reacting quickly to sudden power spikes with extremely low ripple and no flutter to prevent damage to sensitive vehicle electronics.

The unit's fanless cooling system has no moving parts and keeps the ambient operating temperature constant in hot and cold conditions down to -20°C, preventing derating, where heat generated during use causes output voltage to drop and the diagnostic process to fail. It features a clear, multilingual display and fully automatic, 8-step, adaptive charging that analyses lead-acid batteries and selects the optimal current.
