DC Digital Ammeter Current Sensor | SZD07 Overload Protection & Alarm | 0.3-50A Range for Automotive/Solar Systems/Industrial Equipment | DC8-35V Input, Hall Sensor

Electrical surges silently damage your equipment - melted wires, fried controllers, and dead batteries costing hundreds in repairs. Imagine uninterrupted operations where every current spike gets neutralized before disaster strikes. Our SZD07 ammeter is engineered for absolute vigilance. Its Hall sensor detects 0.3-50A fluctuations with industrial-grade accuracy while programmable relays lock down circuits within seconds. See real-time data on the digital display and set custom alarms for your solar array or automotive rig. We include the sensor and ammeter so you can secure your system in one move. Stop guessing about electrical health - master it with laboratory-grade monitoring that works relentlessly in subzero winters or scorching summers.Item Type: DC Digital AmmeterMaterial: PlasticModel: SZD07Input Voltage: DC8-35VMeasurement Type: DC currentRange: 0.3-50ASensor: Hall sensorSensor Input Current: 60ASensor Output Voltage: 2.5±0.625VSampling Frequency: 2 times/sAlarm Output: Upper and lower limit alarms are output from the same relayConnection Capacity: 6A/250VAC, 6A/30VBC, resistive loadWorking Environment: Temperature -10~50℃, temperature Accuracy Level: 0.5 levelPackage List：1 x DC Digital Ammeter1 x Sensor Note:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.

• Real-Time Current Monitoring - DC digital ammeter tracks live current flow with 0.5 accuracy level, displaying accurate readings every 2 seconds. Built for electrical circuit diagnostics to avoid unexpected failures in electrical supplies or battery systems.
• Programmable Relay Alarm System - Hall sensor supports customizable upper/lower limit alerts with delay and return difference settings. Relay connection handles 6A/250VAC loads, delivering immediate protection for motors or inverters when current exceeds secure thresholds.
• Overload Protection Circuit - This current sensor automatically cuts off electrical supply during surges up to 60A input, safeguarding connected devices like solar controllers or car audio systems. High-grade plastic housing resists heat deformation for long-term durability.
• Wide Voltage Compatibility - Operates flawlessly from DC8V to 35V, ideal for RVs, marine batteries, and industrial panels. Installation requires just two wires, reducing setup time to under 5 minutes with included sensor.
• Dual Alarm Security Assurance - Relay outputs simultaneous high/low alerts with 6A/30VDC capacity, eliminating false triggers through adjustable delay. Robust construction withstands -10℃ to 50℃ environments, ensuring year-round stability.
