Technical Parameters & Selection Guide

Selection Criteria: Calculate total current draw of all connected 24VDC loads, including startup surge requirements. Add 20-30% safety margin for future expansion and thermal derating. For applications requiring >8A continuous at elevated temperatures (>60°C), consider the next higher wattage model or implement forced-air cooling. Verify input circuit breaker coordination using the 30A inrush specification.

Extended Functions

Redundancy Configuration Support: When paired with the 1606-XLERED redundancy module (sold separately), enables N+1 backup power architectures. Two or more units operate in parallel with automatic load sharing and seamless failover, ensuring continuous operation during maintenance or component failure.

Remote Monitoring Integration: DC OK relay output provides dry contact status signal for integration with SCADA systems, building management platforms, or remote monitoring solutions. Enables predictive maintenance strategies by tracking power supply health metrics.

Custom Voltage Configurations: Factory customization available for non-standard output voltages (12VDC, 48VDC) or specialized input requirements. Contact technical sales for minimum order quantities and lead times for modified units.

Frequently Asked Questions

What is the recommended circuit breaker rating for this 240-watt power supply?
Use a 10A Type C or D circuit breaker on the AC input side to accommodate the 30A inrush current during cold starts. This prevents nuisance tripping while providing adequate overcurrent protection for the input wiring.

Can I parallel multiple units without the redundancy module for higher current capacity?
No, direct paralleling without the 1606-XLERED module is not recommended. The units lack active current-sharing circuitry, which can result in unbalanced loading and premature failure. Use the redundancy module or select a higher-wattage single unit.

How much energy savings can I expect compared to a linear power supply?
At full 240W load, this switched-mode design dissipates approximately 30W as heat (>89% efficiency). An equivalent linear supply would dissipate 120-150W, reducing cooling costs by 75-80% and lowering panel temperature by 15-20°C in typical installations.

Does this unit require periodic maintenance or calibration?
No scheduled maintenance is required. The electrolytic capacitors are rated for 10+ years at maximum operating temperature. Verify output voltage annually using a calibrated multimeter, and inspect terminal connections for tightness during routine panel inspections.

Is the output isolated from the input for safety compliance?
Yes, the unit provides 4kVAC input-to-output isolation per UL/CE requirements. This galvanic isolation prevents ground loops and protects sensitive control equipment from AC line transients and noise.

What wire gauge should I use for the 24VDC output connections?
For 10A maximum current, use minimum 14 AWG (2.5mm²) copper wire for runs up to 10 meters. For longer distances or to minimize voltage drop, upgrade to 12 AWG (4mm²). Ensure terminal torque does not exceed 0.8 Nm to prevent damage.
