RF4 RF-2003M 60W Regulated Digital Power Supply

Description

The RF4 RF-2003M digital regulated power supply (60W / 15V / 3A) is a fundamental measurement and diagnostic equipment for B2B repair workshops, micro-soldering technicians and refurbishment centres. Specially developed for the analysis of smartphone and tablet motherboards, this stabilized DC voltage source allows you to simulate a battery connection, perform cold boot tests and quickly isolate underlying short-circuited lines without risking damage to surrounding semiconductor components.

In terms of electronic design, the RF4 RF-2003M delivers an adjustable voltage from 0 to 15 Volts and an adjustable current from 0 to 3 Amperes, with a high-precision display resolution reaching 10 mV and 1 mA. The device is built around a regulation circuit with very low thermal and electromagnetic ripple (Low Ripple), guaranteeing a linear electrical signal of exceptional stability (precision <= 0.5%). The front panel features a triple digital LED screen enabling instantaneous and simultaneous reading of voltage (V), current consumption (A) and power output in Watts (W). A 5V / 2A auxiliary USB port is directly accessible on the front panel to power or test the charge of external peripherals.

The station's safety relies on a multi-level architecture incorporating an independent physical output switch (Output button), allowing the technician to interrupt the power supply to the component under test without shutting down the station or altering the saved settings. An automatic overload protection system (Overload Protection) and a T3A/250V protective fuse react immediately to the slightest overcurrent to prevent any destructive thermal shock on iOS and Android motherboards.

Workshop Tip & Usage

For your short-circuit troubleshooting operations via voltage injection on a motherboard (known as the Voltage Injection technique), always make sure to set the voltage limit below the maximum power supply threshold of the targeted line (for example 1.2V to 1.8V for a VDD_MAIN or CPU line) before activating the output via the independent Output switch. Do not use generic, poor-quality starter cables: prefer shielded boot ribbons with low internal resistance to avoid parasitic voltage drops. In case of repeated tripping of the overload protection, check the integrity of your ground braids before modifying the current thresholds.
