About This Product

■DMR-Pro product overview

DMR-Pro is a protection relay for power receiving and substation equipment that integrates protection, control, and measurement. It detects sudden changes in power, current, and voltage that occur in the equipment's power system and controls circuit breakers and other switches to minimize the impact. Implements up to 4 protection elements and can be used in a variety of power receiving and substation equipment, including general industry (50,51,27) and electric railways (47,84).

■DMR-Pro product features

・Integrated protection, control, and measurement Integrates up to four elements of protection functions required for power receiving and distribution equipment, multiple measurement functions such as meters, and circuit breaker control functions into one unit. Achieved space saving and reduced design and assembly man-hours. - Enhanced display functions Improved visibility with the use of a high-brightness white backlight. The large LCD can measure 4 elements simultaneously and display various information such as detected values ​​when an accident occurs. ・Highly reliable design Conforms to electric power standard B-402 (revised May 2016). Duplicated trip circuit and fail-safe function prevent malfunction. A two-behavior method is adopted for the ``on'' and ``off'' operations of the circuit breaker. ・Extensive lineup A lineup of 7 models to suit different applications. JEC/JIS standard products can be used for ZCT. Compatible with a wide range of inputs, including wide-area CT, which eliminates the need for CT replacement even when changing load capacity. ・Various protection characteristics Equipped with 6 types of overcurrent protection characteristics, including a general time limit and a 3-step step time limit. Flexible support is possible even for equipment with severe restrictions on protection coordination. ・Improved workability and maintainability By using a removable terminal block and connector, wiring work can be reduced. Equipped with two types of test modes, contributing to shortening test time during periodic inspections.
