The PD666 series three-phase digital multifunctional meter is a new generation programmable intelligent instrument, which has the functions of measuring three-phase voltage, current, power, power factor, frequency, active energy, and four quadrant reactive energy. It comes standard with RS485 communication interface and can also expand switch input, output, and analog output interfaces; Widely used in electrical measurement and monitoring fields such as smart grids and industrial automation.
Supports three row four position LED display and large screen field LCD display function.
• It can measure three-phase current, voltage, active (reactive) power, power factor, frequency, positive (negative) active energy, and four quadrant reactive energy.
Standard RS-485 communication interface, using standard ModBus RTU communication protocol, baud rate can be set. Expandable switch input.
• Expandable analog output function, with optional transmission specifications of 4-20mA, 0-20mA, and 0-10mA.
• Expandable relay switch output function, capable of achieving upper and lower limit alarm output.
