Allen-Bradley 1756-PB72K ControlLogix DC Power Supply Overview
The Allen-Bradley 1756-PB72K is a conformal coated DC power supply engineered for ControlLogix chassis in demanding industrial environments. Delivering 72W output power with 24-48V DC input range, this unit ensures stable operation in high-humidity, corrosive, and temperature-variable conditions where standard power supplies fail.
Technical Specifications
- Model: 1756-PB72K
- Input Voltage: 24-48V DC
- Output Power: 72W continuous
- Coating: Conformal coating for environmental protection
- Mounting: ControlLogix chassis compatible
- Operating Temperature: 0°C to 60°C (32°F to 140°F)
- Certifications: UL, CE, CSA approved
- Dimensions: Standard ControlLogix module size
Key Applications
This power supply excels in process control systems, manufacturing automation lines, chemical processing plants, offshore platforms, and food & beverage facilities where moisture and contaminants threaten equipment reliability. The conformal coating shields critical circuitry from dust, salt spray, and chemical vapors.
Integration & Compatibility
Seamlessly integrates with ControlLogix 1756 chassis systems. Pair with 1756-PA75 AC Power Supply for redundant configurations, or use alongside 1756-PBM Power Supply Monitor for real-time diagnostics. Compatible with all 1756 I/O modules including 1756-IB16ISOE Input Module.
Why Choose Conformal Coating?
Standard power supplies degrade rapidly when exposed to moisture, dust, or chemical fumes. The 1756-PB72K's conformal coating creates a protective barrier that extends service life by 3-5x in harsh environments, reducing downtime and maintenance costs while maintaining consistent 5V, 3.3V, and 1.2V rail outputs.
Common Questions
Q: Can this replace a 1756-PB75 in existing systems?
A: Yes, the 1756-PB72K is backward compatible with chassis designed for 1756-PB75 units, though verify your total power budget meets system requirements.
Q: What's the difference between K-series and standard versions?
A: The "K" suffix indicates conformal coating for enhanced environmental protection—critical for installations in humid or corrosive atmospheres.
Q: Does it support hot-swap installation?
A: No, always power down the chassis before installing or removing this module to prevent damage.
Q: What warranty coverage is included?
A: All units ship with a comprehensive 12-month warranty covering manufacturing defects and performance issues.
Installation Best Practices
Mount in leftmost chassis slot for optimal heat dissipation. Ensure input voltage remains within 24-48V DC range; use regulated DC source to prevent voltage spikes. Verify chassis backplane connections are clean and corrosion-free before installation. Monitor LED indicators: green = normal operation, red = fault condition requiring immediate attention.
Warranty & Support
Backed by our 12-month comprehensive warranty and technical support team. We stock genuine Allen-Bradley components and ship globally with expedited options available for urgent replacements.
