DEHN DCU 2 YPV 1100 1M 2S DC Combiner Unit for PV Systems, 1100 V DC, 1 MPPT, 2 Strings, IP65 900913

The DEHN DCU 2 YPV 1100 1M 2S combines DC string inputs, surge protection, and a DC disconnect switch in one IP65 enclosure, simplifying PV system wiring and reducing installation time compared to separate components.

Highlights

• Integrated Type 2 surge protection (YPV) per string
• Built-in DC switch disconnector for safe isolation
• Compact polycarbonate enclosure, IP65 rated
• Supports 1 MPPT with 2 input strings, 1 output
• Rated for up to 1100 V DC system voltage

In daily use

This DC combiner unit is designed for wall mounting near the PV array. Connect up to two strings to the screw terminals, route the combined output to the inverter, and use the integrated disconnector for maintenance. The IP65 enclosure protects against dust and water jets, making it suitable for outdoor installation.
