Technical Parameters
- Power supply from monitored DC rail, acceptable voltage 24V..55V DC
- Protection against the wrong polarity of the power supply
- The maximum current through DC transducers: 50A
- The orientation of DC transducer against the DC wire direction is irrelevant; the absolute value of current is measured
- Measurement of DC voltage and current and power
- Radio band 433 MHz, range up to 100m, depending on the shielding of walls and electromagnetic interference
- Measurements every 5 seconds
- DC rail voltage indicated on the Homebase display
- The transmitter is intended for interior use, keep away from moisture, water, snow or ice
