1606-XL480E-3W

Overview

The Allen‑Bradley 1606-XL480E-3W is a compact three‑phase power supply unit characterised by the variety of possibilities of application and low system costs.

Input Specifications

• Nominal input voltage: 3 AC 400...500V, ±15%, 47...63Hz, suitable for IT power systems.
• Rated tolerances:
  • Continuous operation: AC 340...576V resp. DC 450...820V.
  • Please ask for 'application notes' at operation with DC input voltage.
• Input current: 3 x 1.5A.
• Inrush current: < 2.5A eff. resp. < 7A pk.
• Fuse recommendation: 6 A (x3) slow acting fuses (HBC) or supplementary protectors 1492‑SP3C060 recommended. Consult local codes for proper installation.
• 2‑phase operation: Operation is possible even if one phase fails. With high ambient temperature or high load, Pout is adjusted downwards. The red LED is on. Also see Overload Behavior.
• EN 61000‑3‑2 (harmonic current emissions [PFC]) is fulfilled.
• Transient handling: Active transient filter incorporated, so transient resistance acc. to VDE 0160 / W2 (1300V/1.3ms) for all load conditions.
• Hold‑up time: > 11ms at 24.5V/20A, Vin: AC 400V.

Output Specifications

• Output voltage: DC 24...28V adjustable by (covered) front panel potentiometer, preset: 24.5V ±0.5%.
• Output noise suppression: Radiated EMI values below EN 50081‑1, even when using long, unscreened output cables.
• Output protection: Protected against short‑circuit, open circuit and overload.
• Voltage regulation: < 2% static, jumper in 'Single Mode' position.
• Ripple/Noise: < 30mVPP (< 0.1%) incl. spikes (20MHz bandwidth, 50 Ω measurement).
• Overvoltage protection: At 33V ±10%: switch to hiccup mode.
• Power back immunity: max. 35V.
• Parallel operation: Yes, up to ten units.
  • To achieve current sharing: Plug jumper into pos. 'Output parallel use'. This alters the output V/I characteristic to be 'softer' (25V at 2A, 24V at 20A). The output voltage can still be adjusted.
  • Missing jumper = 'Single Use', i.e. 'hard' characteristic.
• Front panel indicator:
  • Green LED on, when Vout = set output voltage.
  • Red LED on, when Vout < set output voltage (with overload and overtemp. as well as overload with 2‑phase op.).
  • Red LED flashes after switch‑off in the Fuse Mode.

Start Behavior

• Start‑up delay: typ. 0.45s.
• Rise time: appr. 5...20ms, depending on load.

Construction / Mechanics

• Housing dimensions (W x H x D): 150mm x 124mm x 121mm (+ DIN Rail).
• Weight: 1.8kg.
