RPS-4M
Introduction
The RPS series redundant power supply uses N+1 parallel current sharing (with Load Balancing) method to achieve power backup and stable power supply, and supports hot swapping design. The RPS series provides communication functions (supports Modbus RTU/TCP) for real-time monitoring, reducing inspection manpower.
- Each slot can plug in a 100W power module
- 4-slot design for N+1 redundancy
- The RPS can provide rated power of 3 power modules (300W) when 4 power modules are inserted.
- The RPS can still supply power at all times when any power module fails. (Number of inserted modules > 1)
- Built-in Load Balancing
The load current will be evenly distributed to each power module to avoid premature failure of one power module due to overuse.
- The power module supports hot swapping
- Built-in power module diagnostic function
- Temperature
- Output current
- Module failure (with one relay output)
- Usage time
- Support Modbus RTU/TCP protocol
Diagnostic information can be access via RS-485, Ethernet
Applications
The RPS series can be used with ICP DAS’s redundant solutions, including I/O redundancy (data acquisition), controller redundancy (program control), ethernet ring communication redundancy (ring network communication) and HMI redundancy (display information record) to form a complete redundant system.
