Necessary for Photovoltaic Power Generation Integrated measurement and protection
Protection relay integrating RPR, OVGR, instrumentation (multimeter), and backup power supply required for photovoltaic power generation equipment. It contributes to system construction with the industry’s most compact size. The OVGR is a top-class multimeter for load-following control in self-consumption photovoltaic power generation systems, with a fast response time (100 ms or less), enabling reductions in power costs and efficient use of energy.
The system is also easy to install, shortening the construction period for additional installation in existing facilities.

Are you looking for a Relay product?
When selecting Relay for your company’s needs, there are several important points to consider during the comparison and evaluation process.
1. Relay Type
Identify the type of relay needed based on its application, such as electromagnetic relays, solid-state relays, thermal relays, or reed relays.
2. Contact Configuration
Compare the contact configurations of different relays, such as normally open (NO), normally closed (NC), or changeover (CO), based on your specific circuit requirements.
3. Current and Voltage Ratings
Check the maximum current and voltage ratings of the relays to ensure they can handle the electrical load and are compatible with the circuit.
4. Switching Speed and Response Time
Evaluate the switching speed and response time of the relays, especially for applications where fast response is critical.
5. Coil Power Consumption
Assess the power consumption of the relay coil to determine its impact on the overall energy efficiency of the system.
6. Electrical Life and Durability
Check the electrical life rating of the relay, which indicates the number of switching cycles it can endure before experiencing failure.
7. Mounting and Form Factor
Consider the physical size and form factor of the relay to ensure it fits within the available space and is compatible with the mounting method required.
8. Coil Voltage and Control
Verify the coil voltage requirements and the control method (AC or DC) to match the relay with the available power source and control circuit.
9. Environmental Conditions
Take into account the environmental conditions in which the relay will operate, such as temperature, humidity, and vibration, to choose a relay with suitable specifications.
10. Brand Reputation and Reliability
Research the reputation of the brand offering the relay and consider the reliability and quality of their products.
