Product: 1phase tester for DC 100V–500V Key benefits Quickly identifies DC voltage in singlephase circuits between 100V and 500V, speeding up troubleshooting and reducing downtime. Designed for safe, accurate testing to help prevent misdiagnosis and reduce the risk of accidental contact. Compact and easy to operate, so you can carry it to job sites and use it without complex setup. Features and what makes it stand out Function: singlephase DC voltage tester for the 100V–500V range. Performance: provides fast, reliable indications to support accurate checks and measurements. Compatibility: probe and tip suitable for slotted screws and common terminal types found in DC installations. Usability: intuitive operation for technicians and electricians; minimal training required. Portability and build: convenient to carry for field or workshop use; built to be durable for regular use. How it solves problems Pinpoints live DC circuits quickly to prevent unnecessary disassembly and reduce troubleshooting time. Helps confirm voltage presence or absence safely, lowering the chance of accidental shock or equipment damage. Fits slotted screws and tight terminal spaces so you can test without removing hardware or using multiple tools. Practical use scenarios Solar installations: check DC output from panels, combiner boxes, and inverters to confirm correct voltages during installation or maintenance. Battery systems and storage: verify voltage on battery terminals and busbars in battery banks and backup power systems. Electronics and electrical maintenance: test DC circuits and connections in industrial equipment, control panels, and field repairs where slotted screw terminals are used. Quick usage notes Use the tester on DC circuits only within the specified 100V–500V range. Place the probe on the slotted screw or terminal contact while following standard safety procedures. Store the tester in an accessible location to ensure it's available for routine checks and emergency troubleshooting.
