PR300 - Yokogawa Power Recorders

Yokogawa PR300 Overview

PR300 is a panel-mounted meter designed to meet two user needs: a power facility meter and a meter for monitoring energy consumption. This panel-mounted power and energy meter with a large, three-row LED display integrates all the measuring functions required for power management in locations such as factories and buildings into a single unit.
With the objective of working toward the preservation of the global environment by saving energy and performing equipment maintenance, the PR300 is designed to display and output the energy of various types of electrical equipment.

• Saves on cost, wiring, and space
  Integrates a wide selection of functions for measuring things like energy (active, regenerative, reactive, and apparent), power (active, regenerative, reactive, and apparent), voltage, current, frequency, and power factor into a single unit
• Employs a large, three-row LED display
  Capable of displaying three-phase current and voltage simultaneously, and the measurement items you assign
• Analog output function
  Equipped with a transducer function for power (active, regenerative, reactive, and apparent), voltage, current, frequency, and power factor (4 to 20 mA DC)
• Demand measurement
  Measures the average power and current within a specified period. It also allows you to set up alarm points to output alarms
• Equipped with a multitude of functions
  Enables measurement of the maximum and minimum values of voltage and the maximum value of current, as well as, for example, the use of external digital input to measure energy at arbitrary times
• Pulse output
  Capable of outputting pulses proportional to energy (one measurement item from active, regenerative, reactive, and apparent energy)
• Converts the phase and wire system of an AC power system and an input voltage circuit to a universal format
  The PR300 can handle from the single-phase two-wire system and single-phase three-wire system to the threephase three-wire system and three-phase four-wire system, and also universally cope with input voltage circuits up to 600 V AC
• Compatible with ANSI 4-inch round form size and DIN 96-square instrument size
  The ability to attach and detach JIS/ANSI-mounting kit makes the PR300 compatible with panel cutouts of ANSI 4-inch round form, JIS 110-square instrument size, and DIN 96-square instrument size
• Standard equipped with an RS-485 communication function and capable of Ethernet communication 
• Compatible with overseas requirements
  Power line indications A, B, and C provided for overseas use, in addition to R, S, and T
