LUMEL P30H data logging DC Power Transducer with RS-485, Ethernet

P30H was designed for photovoltaic, battery, telecommunication and railway installations. P30H measures and records current, voltage, power, energy and other d.c. circuit parameters.

The output signal is galvanically isolated from the input signal and the power supply.

Programmable parameters can be configured with the use of buttons, via RS-485 interface and free e-con software or Ethernet or any web browsers.

Transducer is available in 3 versions:

• basic,
• with SD/SDHC card,
• with Ethernet and internal file system memory.
