DVRR-72
This is one of the smallest protection relays in the market which can be used for solar power generation facilities by integrating RPR, OVGR and power meter in one device.
High speed response time (less that 100ms) as a power meter for load following control for self -consumption PV system.
Adoption of split current sensor make installation easy and shortens the construction period when installing additions to existing facilities.

with Reverse Power Relay (RPR)
and Under Power Relay (UPR) in one device.
Size comparison with AA batteries
Enables power conditioner (PCS) control to match instantaneous fluctuations in power consumption. Highly accurate load-following, self-consumption solar power generation systems that do not generate reverse power can be realized while reducing the amount of power sold by factories, commercial facilities, etc.
Reverse Power Relay (RPR), Over Voltage Ground Relay (OVGR), multi-meter function, and backup power supply are integrated into one unit.
Structural design features high-density internal circuit integration technology, screwless spring-type terminal blocks, and a split-type current sensor. Achieved the industry's smallest class compact body (DIN 72 x 72 mm).
Input by a split-type power sensor allows easy installation even in limited space. Flexible for additional installation work.(Current sensor is optional)
Split-type current sensor
As with our various protection relays and multimeters, use with unbalanced loads is also possible without problems.
