UNIT OVERVIEW

PRECISION DC POWER

> THE ADJUSTABLE DC POWER SUPPLY IS STANDARD-ISSUE LAB EQUIPMENT FOR WEYLAND-YUTANI ENGINEERING, R&D, AND MAINTENANCE DIVISIONS. DELIVERS CLEAN, REGULATED DC POWER FROM 0 TO 30 VOLTS AND 0 TO 10 AMPS — 300 WATTS OF CONTINUOUSLY VARIABLE OUTPUT FOR PROTOTYPING, TESTING, AND COMPONENT CHARACTERIZATION.

> THE HIGH-VISIBILITY 4-DIGIT LED DISPLAY SHOWS VOLTAGE, CURRENT, AND POWER SIMULTANEOUSLY — NO SWITCHING BETWEEN READOUTS. VOLTAGE IS ACCURATE TO 0.01V AND CURRENT TO 0.001A, GIVING YOU PRECISE VISIBILITY INTO EXACTLY WHAT YOUR CIRCUIT IS DRAWING AT ALL TIMES.

> DUAL REGULATION MODES — CONSTANT VOLTAGE (CV) AND CONSTANT CURRENT (CC) — WITH AUTOMATIC CROSSOVER. SET YOUR VOLTAGE AND CURRENT LIMITS, AND THE SUPPLY MAINTAINS WHICHEVER CONSTRAINT IS ACTIVE. ONE-BUTTON OCP ADDS A HARD CURRENT CUTOFF FOR ADDITIONAL CIRCUIT PROTECTION.

> BUILT-IN USB-A AND USB-C FAST CHARGING PORTS DELIVER 18W EACH WITH QC 3.0 SUPPORT — CHARGE DEVICES AND DEVELOPMENT BOARDS DIRECTLY FROM THE BENCH WITHOUT SEPARATE CHARGERS. FOUR PRECISION KNOBS (V-COARSE, V-FINE, A-COARSE, A-FINE) ENABLE RAPID SETUP AND MICRO-ADJUSTMENT.

TECHNICAL CAPABILITIES

POWER CAPABILITIES

30V / 10A ADJUSTABLE

Continuously adjustable voltage from 0 to 30V and current from 0 to 10A delivers up to 300W of clean DC power. Coarse and fine adjustment knobs for both voltage and current provide precision control down to 0.01V and 0.001A.

4-DIGIT LED DISPLAY

Three simultaneous high-visibility LED readouts show real-time voltage (V), current (A), and power (W) at 4-digit precision. No guesswork — see exactly what your circuit is drawing at all times.

CV / CC REGULATION

Automatic switching between Constant Voltage and Constant Current modes. CV mode maintains set voltage regardless of load; CC mode limits current to protect sensitive components. LED indicators show active mode.

OCP PROTECTION

Dedicated Over-Current Protection with one-button enable. Set your current limit and the supply cuts output instantly if exceeded — preventing damage to prototype circuits, components, and connected equipment.

USB-A & USB-C 18W

Built-in USB-A and USB-C fast charging ports with QC 3.0 support deliver 18W each. Charge phones, tablets, and development boards directly from the bench supply without separate chargers.

COARSE + FINE CONTROL

Four precision knobs — V-Coarse, V-Fine, A-Coarse, A-Fine — enable rapid rough adjustment and then precise fine-tuning. Dial in exact voltage and current limits without overshooting or hunting.

CONTROL

PRECISION INTERFACE

V-Coarse / V-Fine knobs

Rapid voltage set with coarse dial, then micro-adjust to 0.01V precision with fine dial — no overshooting

A-Coarse / A-Fine knobs

Set current limit with coarse dial, fine-tune to 0.001A with fine dial — precise current limiting for sensitive circuits

CV / CC mode indicators

LED indicators show whether supply is operating in Constant Voltage or Constant Current mode — automatic crossover

OCP one-button enable

Dedicated Over-Current Protection button adds hard current cutoff — output kills instantly if limit exceeded

OUT button isolation

Set voltage and current before connecting — press OUT to enable output only when you're ready. Safe hot-plug workflow.
