Adjustable DC Power Supply - Precise Voltage

The Adjustable DC Power Supply - Precise Voltage delivers stable, lab-grade energy control for technicians and makers who demand zero guesswork. Engineered for consistent performance, it replaces unreliable adapters with programmable precision.

Digital Readout: Real-time 4-digit LED screen tracks voltage, current, and wattage down to 0.01V and 0.001A resolution.
Independent Output Switch: Single-press ON/OFF button isolates load connections without cutting main power.
Dual Adjustment Knobs: Separate coarse and fine controls prevent sudden surges during calibration.
Multi-Stage Protection: Integrated safeguards automatically trigger during over-voltage, short-circuit, or thermal events.
Integrated Charging Port: Front-mounted 5V 2A USB outlet powers mobile gear without draining workspace outlets.

This Adjustable DC Power Supply - Precise Voltage eliminates equipment damage by enforcing safe thresholds before circuits fail. The auto-switching constant-voltage and constant-current modes maintain steady delivery across dynamic loads, while the temperature-aware cooling system reduces acoustic noise and extends operational longevity.

5 Frequently Asked Questions:

Is reverse polarity protected? Yes, internal diode arrays prevent backward current flow to sensitive modules.

Can I stack two units for higher current? No, each unit operates independently; parallel wiring requires external synchronization hardware.

Does the display show remaining time? The 4-digit matrix focuses exclusively on electrical parameters to minimize signal lag.

What cable gauges are included? The package contains heavy-duty red/black leads rated for sustained multi-amp draw.

How does over-temperature shutdown activate? Thermal sensors halt output once internal temperature exceeds 50°C until passive cooling restores baseline levels.

Use Cases:

Deployable across automotive ECU bench testing, educational circuit demonstrations, and low-noise sensor validation environments.
