## Long description

The Dehn DEHNcombo YPV 1200 is a high-performance combined lightning current and surge arrester specifically engineered for photovoltaic systems. Operating at a rated voltage of 1200V DC, this Type 1+2 device serves as a critical safety component, protecting sensitive solar power equipment from the damaging effects of atmospheric discharges and transient switching surges. Its robust design ensures consistent performance in demanding electrical environments, helping to maintain the operational integrity and longevity of solar installations.
Advantages
This surge protection device offers a comprehensive solution by combining Type 1 and Type 2 protection in a single, space-saving unit. By effectively limiting transient overvoltages, it significantly reduces the risk of equipment failure and costly downtime. The compact architecture allows for seamless integration into existing PV string boxes or near inverters, simplifying the installation process while maintaining high safety standards for direct current circuits.
Suitable for
Photovoltaic power systems operating up to 1200V DC
Protection of solar inverters and charge controllers
Integration into PV string boxes and combiner boxes
Residential and commercial solar energy installations
When it may not be suitable
This device is specifically designed for DC circuits in photovoltaic systems and should not be used for AC grid-side protection. It is also not suitable for systems exceeding the rated voltage of 1200V DC, as this would compromise the safety and functionality of the arrester.
Key specifications
Type: 1+2 combined lightning current and surge arrester
Rated voltage: 1200V DC
Application: Photovoltaic systems
Design: Compact, modular construction
How to use
The device should be installed by a qualified electrician in accordance with local electrical regulations and safety standards. It is typically mounted on a standard DIN rail within the PV string box or the inverter enclosure. Ensure that the connections are secure and that the grounding path is properly established to allow the device to divert surge currents effectively. Regular visual inspection of the status indicator is necessary to ensure the device remains operational.
What to consider before purchase
Verify that your PV system voltage does not exceed 1200V DC
Ensure there is sufficient space on the DIN rail for installation
Confirm compatibility with your existing surge protection coordination plan
Check local electrical codes regarding lightning protection requirements
Usage recommendations: It is recommended to perform periodic checks of the status indicator to confirm the device is still providing active protection. If the indicator shows a fault, the module should be replaced immediately to ensure continued safety of the photovoltaic system.
