Dell TK-DCX05030C 5 V USB-C Charger Barrel Connectors

Dell TK-DCX05030C USB-C power adapter

The Dell TK-DCX05030C is a 5 V USB-C charger that carries barrel connectors at both ends. It functions as a buck-boost converter with adjustable output from 0.6 V to 36 V and a current limit up to 5 A. The module includes an LCD showing voltage, current, power, capacity, time and temperature. Multiple protections cover reverse connection, overvoltage, overcurrent, overpower and overtemperature.

Suits bench testing and prototyping

This unit suits engineers and hobbyists who need a compact, adjustable DC supply with real-time readouts. It works well for powering development boards, LED strings or small motors where precise voltage and current limits matter. Buyers who need a fixed-voltage laptop charger or a high-wattage desktop supply should look elsewhere. The 50 W enhanced dissipation ceiling also rules out heavy continuous loads.

Simple bench integration

Connection is straightforward: feed 5 V to 30 V into the input barrel jack and set the desired output with the onboard controls. The intelligent fan starts automatically above 50 °C or 1 A, so no manual thermal management is required. A common issue is the soft-start behaviour; heavily capacitive loads can prevent the module from starting, so enable the load after the output is stable. The LCD cycling button lets you switch between current, power and other parameters without tools.
