EX BATTERY CHARGER
Explosion proof Battery Charger
Space efficient, natural cooled, high-tech modular battery charger solution with optimized electrical performance and no maintenance by design. Completely designed for reliable operation in extreme harsh environment and IECEx/ATEX certified for hazardous area zone 1 with optimized thermal management.
Key features
- Highest power density / Smallest footprint
- Hight Efficiency with a very high power-factor close to unity
- Compact design, utilize SMPS MOSFET technology with built in isolation transformer to ensure galvanic isolation between input and output
- Best in class THD
- Low inrush current and soft start behaviour
- No maintenance by design (no replacement of parts during lifetime)
- Suitable for installation in offshore harsh environments
- Modular design and internal redundancy provides maximum availability and makes it suitable for N+N or N+1 redundancy design to ensure reliable and quality power supply
- Smart, local and remote control and monitoring by Ex-d touch screen (access with door closed)
- Natural cooling design optimizes reliability, not reliant on forced cooling
- Maximum safety with Ex-d and Ex-e enclosures
