Solving Problems in the Photovoltaic Systems Era

Safely Measure High Voltages and Analyze Harmonics

In recent years, there has been a demand for improved work efficiency using IoT to compensate for the aging of people involved in the management and maintenance of electrical equipment and the phenomenon of employees. In addition, the use of high-voltage solar power generation and EV batteries is increasing, and new maintenance demands are also expanding.

To meet these demands, DT4261 has been developed as a measuring instrument that uses IoT to improve working efficiency and can measure high voltages exceeding DC1000V.

Supports Measurements up to DC 2000V for PV Solar Systems with P2000 Probe (to be released in December 2021)

The increasing prevalence of large Photovoltaic Systems comes with the increasing need of measuring voltages above DC 1000V. The DT4261 safely supports measurements between ground to DC 2000V (CAT III 2000V, CAT IV 1000V) with the optional DC High Voltage Probe P2000

P2000 to be released in December 2021.

Analyze Issues caused by Harmonics in the Field

When combined with GENNECT Cross, you can perform simple harmonic analysis. Applications include harmonic measurement of power conditioners for solar systems and problem analysis of power supply systems.

See here for details about GENNECT Cross

Problems that can be caused by harmonics

  • Equipment burn-out and destruction due to overheating
  • Malfunctions of power control devices
  • Increased loss along with reduced service life and efficiency for power devices

Boost Work Efficiency with Digitalization (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®.

Auto Fuse Check Function – Prevents Incorrect Current Measurement

When switching from the clamp function to the current function, a fuse disconnection check is automatically performed.

This allows the user to know if the fuse is broken before current measurement, which prevents erroneous measurement.

Stop Worrying about Losing Test Lead Caps with L9300

Test Lead L9300 incorporate integrated caps for greater convenience and safety. The design lets you change the measurement category simply by sliding the test lead’s protective finger guard. You no longer have to worry about losing caps!

Ensuring safety by preventing erroneous test lead insertion with terminal shutters

Due to the current terminal’s low impedance, measuring voltage after erroneously inserting a test lead into the current terminal will cause the fuse to blow. The DT4261’s terminal shutters are linked to the instrument’s rotary switch such that they block access to test lead terminals that aren’t being used, making it physically impossible to insert a lead into the wrong terminal

Excellent Dust and Water Resistance (compliant with the IP54 international standard)

Highly dust-proof and water-proof suited for rugged use
