1 General Specifications Model PR300 Power and Energy Meter GS 77C01E01-01E Oeriew This panel-monted power and energy meter with a large, three-row ED display integrates all the measring fnctions reqired for power management in locations sch as factories and bildings into a single nit. With the objectie of woring toward the preseration of the global enironment by saing energy and performing eqipment maintenance, the PR300 is designed to display and otpt the energy of arios types of electrical eqipment. Featres Saes on cost, wiring, and space Integrates a wide selection of fnctions for measring things lie energy (actie, regeneratie, reactie, and apparent), power (actie, regeneratie, reactie, and apparent), oltage, crrent, freqency, and power factor into a single nit. Employs a large, three-row ED display Capable of displaying three-phase crrent and oltage simltaneosly, and the measrement items yo assign. Analog otpt fnction Eqipped with a transdcer fnction for power (actie, regeneratie, reactie, and apparent), oltage, crrent, freqency, and power factor (4 to ma DC). Demand measrement Measres the aerage power and crrent within a specified period. It also allows yo to set p alarm points to otpt alarms. Eqipped with a mltitde of fnctions Enables measrement of the maximm and minimm ales of oltage and the maximm ale of crrent, as well as, for example, the se of external digital inpt to measre energy at arbitrary times. Plse otpt Capable of otptting plses proportional to energy (one measrement item from actie, regeneratie, reactie, and apparent energy). Conerts the phase and wire system of an AC power system and an inpt oltage circit to a niersal 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 for-wire system, and also niersally cope with inpt oltage circits p to 600 AC. Compatible with ANSI 4-inch rond form size and DIN 96-sqare instrment size The ability to attach and detach JIS/ANSI-monting it maes the PR300 compatible with panel ctots of ANSI 4- inch rond form, JIS 0-sqare instrment size, and DIN 96-sqare instrment size. Standard eqipped with an RS-485 commnication fnction and capable of Ethernet commnication Compatible with oerseas reqirements Power line indications A, B, and C proided for oerseas se, in addition to R, S, and T ANSI 4-inch rond form size The ability to attach and detach JIS/ANSI-monting it ensres compatibility with two sizes.
