TBK 218 Adjustable DC Bench Power Supply 0-30V 0-10A | Digital Waveform & Analog Meter

The TBK 218 is a professional-grade DC regulated power supply engineered for precision electronics repair and laboratory testing. Capable of delivering a stable, adjustable output of 0-30V and 0-10A, this unit is powered by a robust 300W toroidal transformer, ensuring low-noise and consistent power delivery even under heavy loads. The device distinguishes itself with a hybrid display system: a 4.3-inch HD IPS screen for digital readouts and real-time waveform plotting, alongside a high-sensitivity analog pointer meter. This combination allows technicians to monitor dynamic current consumption and analyze circuit boot sequences effectively. With integrated short-circuit protection and multiple USB outputs, the TBK 218 serves as a versatile diagnostic center for mobile phone logic board repair and general electronics maintenance.
