Core Positioning: The "Universal Power Adapter" for Uninterrupted Test Operations

　　For test engineers, R&D technicians, and on-site testing teams, traditional power supplies fail to meet three critical test equipment needs: interface incompatibility (multiple test devices require different DC connectors), single-device limitation (one power supply for one piece of equipment, causing redundancy), and on-site power gaps (no matched power supply for emergency testing). This interchangeable power supply with universal DC connectors solves these pain points through full-coverage universal DC interfaces, modular replaceable power modules, and test-grade stability, enabling "one power supply for multi-device compatibility (5V-30V), 10-second module swapping for continuous power, and stable voltage output to protect test data accuracy". It acts as a versatile power core for test equipment—no more carrying multiple power supplies or halting tests due to mismatched connectors.

　　Three Core Advantages for Test Equipment Scenarios

　　1. Universal DC Connectors: Cover All Test Device Interface Needs

　　Full-Range Connector Compatibility: Equipped with 8+ commonly used DC connectors for test equipment, including DC barrel plugs (5.5×2.1mm, 4.0×1.7mm), terminal blocks (screw-type for high-current devices), USB-C PD (for low-voltage test tools like multimeters), and custom adapter sleeves (compatible with proprietary interfaces of spectrum analyzers, signal generators). No need for additional adapter cables—direct plug-and-play for 95% of test equipment (e.g., Keysight oscilloscopes, Rohde & Schwarz signal sources).

　　Adjustable Voltage & Current: Supports stepless voltage adjustment (5V-30V) and current limiting (0.5A-10A), matching the power requirements of different test devices: 5V/2A for digital multimeters, 12V/5A for low-power signal generators, 24V/8A for high-performance spectrum analyzers. Voltage regulation accuracy ±0.5% and ripple & noise <50mV—avoids voltage fluctuations affecting test data (e.g., signal amplitude measurement errors).

　　Smart Interface Detection: Built-in connector recognition function, automatically matching the optimal voltage range for the connected test device (e.g., detecting a USB-C PD test tool and switching to 5V/3A mode). Prevents overvoltage/overcurrent damage to precision test equipment (critical for R&D prototype testing).

　　2. Interchangeable Power Modules: Flexible Power Supply for Any Scenario

　　Modular Replaceable Design: Adopts 2-in-1 power supply mode—"built-in rechargeable module + external AC adapter module":

　　Rechargeable module (10000mAh lithium-ion, 18Wh): Supports 4-6 hours of continuous power for low-power test tools (e.g., handheld oscilloscopes) during on-site testing (no AC power access).

　　AC adapter module (100-240V universal input): Provides uninterrupted power for laboratory long-duration tests (e.g., 24-hour stability testing of RF modules).

　　Modules can be swapped in 10 seconds via a quick-release latch—no tools required, ideal for emergency power switching (e.g., on-site AC power failure, switching to rechargeable module instantly).

　　Lightweight & Portable: Single module weighs only 320g (11.3oz), and the whole unit (with 2 modules + connector set) weighs 850g (30oz)—smaller than a standard 15-inch laptop charger. Fits easily in test equipment backpacks or field toolkits, reducing the burden of carrying multiple dedicated power supplies.

　　Dual Power Input/Output: The AC module supports simultaneous power supply to the test device and charging of the rechargeable module (20W fast charging, 1.5 hours full charge). Ensures the rechargeable module is always ready for on-site emergency use.

　　3. Test-Grade Stability: Protect Test Data & Equipment Safety

　　High-Precision Voltage Regulation: Uses a synchronous rectification circuit and digital feedback control, achieving voltage regulation accuracy ±0.5% and load regulation ±1%—meets the power stability requirements of precision test equipment (e.g., avoiding voltage drift affecting oscilloscope waveform sampling).

　　Comprehensive Protection Mechanisms: Equipped with overvoltage protection (OVP), overcurrent protection (OCP), short-circuit protection (SCP), and overtemperature protection (OTP). Automatically shuts down output when abnormalities occur (e.g., test device short circuit), preventing damage to expensive test equipment (e.g., $10k+ spectrum analyzers).

　　Anti-Interference Performance: Passes MIL-STD-461F EMI/EMC tests, with low electromagnetic radiation and strong anti-interference capability. No signal interference with RF test equipment (e.g., avoiding noise affecting signal generator output purity) during laboratory or on-site testing.

　　Empowering Test Equipment Scenarios

　　Laboratory R&D Testing: One power supply replaces 5+ dedicated power supplies for oscilloscopes, signal generators, and prototype boards. Universal connectors reduce desktop clutter, and AC module’s uninterrupted power supports 72-hour stability testing of new products (e.g., IoT module signal testing).

　　On-Site Equipment Debugging: Rechargeable module provides 5-hour power for handheld test tools (e.g., portable spectrum analyzers) during outdoor base station debugging. Quick-swappable modules solve emergency power shortages (e.g., swapping a fully charged module in 10 seconds to continue fiber optic tester operation).

　　Field Maintenance & Calibration: Universal DC connectors ensure compatibility with field test devices (e.g., power meters, network analyzers) without carrying multiple adapters. Voltage adjustment function meets the calibration needs of different precision instruments (e.g., adjusting to 15V for calibrating industrial sensors).

　　Educational & Training Labs: Multi-device compatibility reduces the cost of purchasing dedicated power supplies for student test stations. Built-in protection mechanisms prevent equipment damage from incorrect operation (e.g., student miswiring leading to short circuits).

　　Test Equipment-Focused Cooperation & Support

　　Compliance & Safety: Certified by CE, FCC, RoHS 2.0, and IEC 61558 (safety standard for power supplies). Meets the electromagnetic compatibility requirements of test equipment (EN 61326-1) to avoid affecting test data accuracy.

　　Customization Services: Offers custom DC connectors (e.g., proprietary interfaces for specific test equipment brands like Tektronix, Anritsu) and voltage range expansion (up to 48V for high-voltage test tools). Provides pre-configured packages for test labs (e.g., 10-power-supply kits with full connector sets).

　　Technical Support & Calibration: Provides free 1-year calibration services (traceable to NIST/CNAS) to ensure voltage/current accuracy. 24/7 technical support team (with test equipment expertise) assists in adapting to special devices (e.g., matching power parameters for custom R&D test benches).

　　Bulk Supply & Delivery: Monthly production capacity of 50,000 units, delivery cycle ≤ 3 weeks. Offers flexible packaging (individual toolkits for field teams, rack-mountable bundles for laboratories) to meet different procurement needs.
