Rockwell Automation Introduces New Line of Switched-Mode Power Supplies for Low Voltage Control Applications

Allen-Bradley® Bulletin 1606 power supplies deliver improved safety and reliability in a compact, easy-to-install package

MILWAUKEE, July 28, 2003 — To meet the increased safety and reliability demands required for many low-voltage power supply applications, Rockwell Automation has introduced a new line of general-purpose switched-mode power supplies – the
Allen-Bradley® Bulletin 1606. The comprehensive line of low-voltage power supplies accepts wide ranges of both AC and DC input voltages and has global approvals to meet worldwide single-phase and three-phase application requirements.

Comprised of two distinct families – the 1606-XL (standard) and 1606-XLP (compact) – the Allen-Bradley Bulletin 1606 power supplies feature start-up and overload response capabilities that provide smooth electrical load distribution. The standard units are designed with a power boost that provides additional power reserves of up to 15 percent without any reduction in output voltage. All units feature an overload design that delivers up to 80 percent higher continuous current (above maximum device rating) at a reduced voltage, with no negative thermal effects. This eliminates the need for designers to oversize the power supply system and minimizes potential overload damage.

When wired in parallel with an identical device, the special, redundant power supplies provide 1+1 redundancy with no need for additional hardware. The result: panel designers are able to achieve greater cost efficiency because they no longer need to buy extra components to build a redundant design.

In conditions where input power is unreliable, the Allen-Bradley 1606-XLBUFFER module gives panel designers an extra measure of protection against unpredictable threats, such as voltage dips or “brownouts.” This supplementary module accommodates input power fluctuations by allowing the control circuitry to bridge over voltage dips and keep the system running. The buffer unit is compatible with 5 to 20A, single-phase and three-phase supplies and provides DC power backup for all types of AC power faults.

With the smallest per-watt profile in the industry, the 1606-XLP compact power supplies feature a frame size that is 50 percent smaller than most comparable units, while providing the same performance advantages as the standard devices. In addition, all compact power supply units are DIN-rail-mounted and feature spring-clamp terminations that require no tools to install. This speeds installation, reduces wiring costs and provides a stable electrical connection under high vibration conditions.

The Bulletin 1606 power supplies offer efficiencies ranging from 85 to 93 percent and provide cost-effective redundancy for 2.5-, 5-, 10-, 20- and 40-amp applications.
