HR1520 adjustable regulated DC power supply — stable 0–15 V DC, 0–20 A output, designed for precise, reliable testing and burnin applications. Key benefits Stable, lownoise power for sensitive electronics: frequency toroidal transformer minimizes voltage ripple and reduces energy consumption, delivering clean power for accurate test results and safe device aging. Fast, precise control: realtime voltage and current shown on a large multidigit color display, with load stability ≤0.001±2mV and response time ≤100µs for quick, repeatable adjustments. Protects your devices and saves troubleshooting time: builtin overcurrent and overvoltage protection plus an intelligent shortcircuit location function with buzzer alert prevents damage and speeds fault finding. Quiet, durable cooling for extended use: sevenblade brushless cooling fan provides rapid heat dissipation at low noise levels so the supply can run long tests without overheating. Compact, versatile, and easy to use: lightweight (0.55 kg) and compact (10 × 12 × 4.5 cm), fits on crowded benches and integrates into lab racks or production stations. Universal 110–220 V input supports global use.

Speeds fault diagnosis: fast response time and shortcircuit locator reduce downtime during development or production testing. Prevents equipment damage: builtin protections guard prototypes and finished devices during prototyping, , or automated testing. Fits limited workspaces and portable setups: small footprint and light weight make it easy to move between benches, labs, or field service jobs. Typical applications Electronics testing and development: bench power for circuit debugging, component evaluation, and lab experiments requiring stable DC supply. PCB burnin and aging tests: continuous, lowripple power for prolonged stress testing and quality assurance on production lines. Mobile device and assembly: stable power for charging tests and functional checks on phones, tablets, and other consumer electronics. What makes HR1520 stand out Combines current capacity (up to 20 A) with precision control and rapid response. Intelligent protection and audible shortcircuit location save time and protect hardware. Compact, energyefficient design using a frequency toroidal transformer for lower ripple and reduced power loss. Package suitability and compatibility Compatible with a wide range of DCpowered electronics: mobile phones, tablets, development boards, sensors, and small appliances under 15 V/20 A. Suitable for laboratories, R&D teams, shops, smallscale production, and automated test environments. User controls and convenience Clear, colorful numeric display for immediate readout of voltage and current. Metaltextured rotary knob with clicktoswitch mode and smooth fine adjustment. Simple language switching between Chinese and English for broader usability. Safety and operation notes Observe the specified 0–15 V and 0–20 A limits to avoid triggering protection circuits. Ensure correct wiring and proper ventilation when running extended tests to maintain cooling.
