M7103

3-Channel Power Measurement Module for LR810x Data Logger Series

Key Features

• Up to 12 / 120 power channels
• Power accuracy: 0.02% rdg. ± 0.05% f.s.
• 1500 VDC / 1000 VAC, CATII
• 5 ms update interval
• DC to 100 kHz bandwidth 

The M7103 power measurement module for LR810x data loggers offers three channels for highly accurate power logging. One LR8101 or LR8102 Data Logger in combination with the M1100 AC power supply module supports up to four M7103 modules, giving the user the ability to log up to 12 power channels simultaneously with one logger. Up to 120 power channels can be recorded by synchronizing multiple LR8102 Data Logger. 

The voltage input channels are designed for direct input of voltages of up 1500 VDC or 1000 VAC, CATII making the M7103 ideal for safe and reliable production line testing. All HIOKI high-precision current sensors with an ME15W connector can be combined with the M7103 power measurement module, offering users the flexibility to choose the ideal current sensor for their specific application. With an update interval of just 5 ms, the module enables detailed logging of power, voltage, or current with exceptional precision.

The sync source sharing feature ensures precise efficiency measurement by using the AC signal's zero-crossing for calculation to synchronize a primary module with secondary modules, making the system ideal for high-accuracy applications like quality inspection in PV string inverter production. This highly flexible logger system offers the possibility to easily expand channels on-site without the necessity to return the equipment to the factory, saving valuable time.
