Fast & Reliable
Hioki IR5051-90 PV High-Voltage Insulation Tester with wireless adapter, 2000 V is available at EquipTestPro.com with fast shipping and great prices.
Features
Dedicated Measurement Function
In addition to a normal insulation resistance measurement mode, the IR5051 also features a specialized mode for measuring PV insulation resistance.
Flexible Voltage Range
Effectively measures 1500 V solar PV systems and is prepared to accommodate systems up to 2000 V as technology advances.
Standards Compliance
Complies with IEC 62446-1 for Category 1 and Category 2 tests, ensuring robust safety and performance
Measure insulation resistance while the solar PV system continues to generate
The CAT III 2000 V and CAT IV 1000 V rated IR5051 can measure insulation resistance and open-circuit voltage in solar power systems up to 2000 V safely.
The IR5051 has a PV insulation resistance measurement function. It features the ability to measure even while PV systems are generating power. This means you don’t have to wait until night for measurement or stop power generation.
Identify ground faults in solar power systems using our free app, GENNECT Cross
The CAT III 2000 V and CAT IV 1000 V rated IR5051 can measure insulation resistance and open-circuit voltage in solar power systems up to 2000 V safely.
Intuitive and precise high-voltage insulation testing
Easy-to-use insulation resistance meter with intuitive rotary knob operation.
Precision stability in high voltage insulation testing
When the test object has very high resistance, the insulation resistance meter measures minute currents. Because such measurements are sensitive to even minor changes in the environment, the readings can become unstable. The IR5051 reduces environmental influences using shielded wires, and its unique measurement technology enables stable measurements up to 10 TΩ.
Tailored measurement methods with advanced insulation diagnostic functions
When a high test voltage is continuously applied to the circuit under test, the insulation may break down. Failures caused by the application of a high voltage can be prevented by keeping the applied voltage as low as possible while testing the insulation.
The IR5051 is equipped with various insulation diagnostic functions, allowing you to choose the optimal measurement method according to the testing application.
Automatically calculated and displayed insulation diagnostics
After measurement completes, the instrument can display more than just the insulation resistance and leakage current, but also judgement index values of PI, DD, and DAR. It calculates these indexes based on the measured values and displays it as a pass/fail judgment.
High-Safety design insulation resistance meter
CAT III, CAT IV rated IR5051 hold the highest standards in safety performance. You may think that insulation resistance measurement is not dangerous because it is performed under power outage conditions, but on the contrary, accidents can be dangerous. The IR5051 have enhanced safety performance in case of such an accident.
Start test: Press and hold for 1 sec. to start measurement. This feature helps prevent inadvertent activation of a high voltage.
To encourage caution, the MEASURE button flashes when a high voltage is being generated or discharged.
Complete: The IR5051 will start discharging automatically as soon as the test is over. During this time, the test start button will flash red to indicate that it is discharging.
Wireless support (*1)
Installing the Wireless Adapter Z3210 on the instrument enables Bluetooth® wireless communication, facilitating the transfer of measurements to your smartphone or tablet.
*1: Wireless Adapter Z3210 is necessary.
Enhance your insulation resistance meter with GENNECT Cross
A time-series graph of the current provides a visualization of the insulation state of a high-voltage cable. Utilize the logging function of GENNECT Cross to generate time-series graphs of data recorded at one-second intervals, enhancing the analysis and understanding of trends.
Field Maintenance function: Using a picture of the site, this function can display the measurement values where the measurements are made.
Report function: Easily create PDF reports with measurement results.
Excel® Direct Input Function
Boost work efficiency in the field by letting you directly transfer measurement data to (i.e., enter measured values directly into) templates created as Excel®.
Wireless Adapter Z3210 is necessary.
Transfer data via USB after measurement
Transfer measured values and logging data saved on the instrument to a PC via USB (*2). This function requires Sequence Maker, a free Excel add-in.
*2: DMM Communicator DT4900-01 is required (sold separately).
Dustproof & waterproof case for outdoor work
The Carrying Case C0212 is a rigid case with IP65 dust and water protection. It provides space for the insulation resistance meter and test leads so that they can be transported easily.
