Nexa® 1200
1.2 kW Fuel Cell System
The Nexa® 1200 is the new generation of power modules within the Nexa class. Based on the modern FCGen™ 1020 Stack from Ballard, the system convinces through an improved system efficiency and a higher stack lifetime.
- Rated voltage: 24 V
- Rated current: 52 A
- Rated output: 1200 W
- Output voltage: 22 … 36 V
Simplest integration
The fully-integrated module has an enclosed, robust housing and flat design. Profile rails integrated into the housing offer simple and variable attachment possibilities. The installation position and air ducts are variably adjustable to the application. Wall mounting or installation in a 19” rack can be easily achieved.
High level of system efficiency
An innovative system design and the selection of energy efficient peripheral components allow for an increase of overall system efficiency of up to 15% in comparison to the Nexa Power Module from Ballard.
Communicative system
The Nexa® 1200 has tolerant and easily accessible interfaces. A central interface hub on the back of the system houses all interfaces and connectors in one place. The system communicates via CAN-Bus.
Accessories
