1606-XL240E

Overview

1606-XL240E is a high-performance switched mode power supply from Rockwell Allen-Bradley, designed for industrial applications requiring reliable 24V DC output with robust overload handling and EMI suppression.

Input Specifications

• Input Voltage:

  • AC: 100–120 / 200–240V (switchable), 47–63 Hz

  • AC Range: 85–132 / 176–264V

  • DC Range: 240–375V (switch must remain in 230V position)

• Input Current:

  • <6A (115V switch position)

  • <2.6A (230V switch position)

  • DC-in at open output: 8 mA (preserves battery sources)

• Inrush Current (Typical): <30A at AC 264V, cold start

• Recommended Fuse: 10A slow-acting (HBC) or 1492-SPU1C100 supplementary protector

Efficiency & Reliability

• Efficiency (Typical): 90% @ AC 230V, 24V/10A

• Power Losses (Typical): 26.7W @ AC 230V, 24V/10A

• Hold-up Time: >25 ms @ AC 196V, 24V/10A

• MTBF: 425,000 hours (Siemensnorm SN 29500 @ 24V/10A, AC 230V, Tamb = +40°C)

• Electrolytic Capacitor Life: Long-life rated for +105°C

Start / Overload Behavior

• Startup Delay: Typical 0.1 s

• Rise Time: Approx. 5–20 ms (load-dependent)

• Overload Design:

  • No disconnection or hiccup under overload

  • Supports up to 1.6 × INom with gradual voltage reduction

  • 20% power boost: 12A short-term; continuous at 45°C or with forced cooling

• Advantages:

  • High short-circuit current for reliable startup

  • No fold-back “sticking” behavior

  • Reliable secondary fuse operation

Output Specifications

• Output Voltage: 24–28V DC (adjustable via front panel potentiometer, preset: 24.5V ±0.5%)

• Voltage Regulation: Better than 2% overall

• Ripple / Noise: <30 mVpp (20 MHz bandwidth, 50Ω measurement)

• Overvoltage Protection: Typical 35V

• Power Back Immunity: 34V

• Parallel Operation: Supported; load sharing available on request

• Protection: Short-circuit, open circuit, and overload

Environmental Ratings

• Operating Temperature: 0°C to +70°C (derating above +60°C)

• Storage Temperature: –40°C to +85°C

• Humidity: Max 95%, non-condensing

• Derating: Typical 6W/K from +60°C to +70°C

Load Ratings

• Continuous Loading with Convection Cooling:

  • Tamb = 0°C to 60°C:

    • 24V/10A (240W)

    • 28V/8.6A (240W)

  • Tamb = 0°C to 45°C:

    • 24V/12A (288W)

    • 28V/10.3A (288W)

  • Short-term operation also supported at 60°C

EMI & Indicators

• EMI Suppression: Radiated values below EN50081-1, even with long, unscreened output cables

• Front Panel Indicator: Green LED
