Backplane Bus Communication Velocity & Enclosure Integrity
The 1606-XL240E power module delivers regulated DC distribution to preserve backplane bus communication velocity across high-density I/O chassis assemblies. Featuring switchable single and parallel operating modes via jumper selection, the unit supports up to five parallel operations for high I/O density scaling. Dual front-panel LEDs (green and red) provide real-time diagnostic feedback, while internal electronic components rated for 105 deg C ensure long-term thermal dissipation stability.
Frequently Asked Questions
Q: What is the preset output voltage of the 1606-XL240E power supply, and can it be adjusted?
A: The front panel potentiometer features a factory preset of 24.5 VDC with a guaranteed adjustable output range.
Q: How many 1606-XL240E units can be connected in parallel for redundant configurations?
A: The module supports up to five parallel units when configured in parallel mode via the onboard jumper.
Field Installation Guidelines
Mount the 1606-XL240E securely onto a standard 35 mm DIN rail within the control enclosure, ensuring proper vertical spacing for thermal convection.
Connect the three-phase 480 VAC input lines to the primary terminals, verifying that the dedicated primary fuse is installed prior to energizing.
Set the operating mode jumper to single or parallel mode depending on system load redundancy requirements before connecting DC outputs.
Connect protective earth (PE) grounding conductors to maintain surge protection performance and reduce high-frequency electrical noise.
