PM820

The PM820 is a Power Meter that offers high-performance measurement capabilities needed to monitor an electrical installation in a compact 96 x 96mm unit. It offers custom on-board logging and individual current and voltage harmonic readings and an incremental choice of custom logging and power quality analysis capabilities. It mounts using two clips, with no tools required and offers billing (energy and demand), maintenance, alarm and customizable data logs, all stored in non-volatile memory. It offers five channels for demand metering of water, air, gas, electricity or steam utilities (WAGES) through the pulse counting capabilities of the digital inputs. Pulses from multiple inputs can be summed through a single channel. Power meter include an RS-485 port supporting Modbus protocol (ASCII and RTU). An optional module provides Ethernet Modbus TCP/IP communications with e-mail on alarm, full function web server and Ethernet-to-serial line gateway functionality.
