Description

The PACIFIC 6445-001-K-N is a high-reliability industrial switching power supply designed to deliver stable, regulated 24 V DC power to automation systems in demanding environments. Manufactured by Pacific Scientific (later acquired by Danaher and integrated into the broader industrial controls portfolio), this module is widely used in legacy and current-generation control panels for PLCs, I/O racks, relays, and instrumentation. The PACIFIC 6445-001-K-N features universal AC input capability, robust protection circuitry, and a compact DIN rail form factor—making it ideal for space-constrained cabinets in process and discrete manufacturing.

As part of Pacific’s 6400 series of industrial power supplies, the PACIFIC 6445-001-K-N emphasizes simplicity, durability, and long service life without requiring active cooling. Its convection-cooled design eliminates fans—a common point of failure—ensuring silent, maintenance-free operation even in dusty or corrosive settings. The PACIFIC 6445-001-K-N is frequently specified as a direct replacement in systems originally built with Allen-Bradley, Modicon, or GE Fanuc controllers, where consistent voltage regulation is critical to preventing logic faults or communication dropouts.

Main Features and Advantages

Fanless reliability for continuous operation: The PACIFIC 6445-001-K-N operates entirely through natural convection cooling, eliminating moving parts that degrade over time. This design significantly enhances mean time between failures (MTBF)—often exceeding 100,000 hours—and makes the unit suitable for environments where dust, moisture, or explosive atmospheres prohibit fan use.

Universal input for global deployment: With an ultra-wide input range (85–264 V AC or 100–370 V DC), the PACIFIC 6445-001-K-N automatically adapts to varying line voltages without manual switches or jumpers. This simplifies inventory management for multinational plants and ensures uninterrupted operation during brownouts or voltage sags—common in remote industrial sites.

Comprehensive protection safeguards downstream equipment: The PACIFIC 6445-001-K-N includes automatic recovery from short circuits, fold-back current limiting during overloads, and crowbar-style overvoltage clamping. If internal temperature exceeds safe limits, thermal shutdown engages and resets only after cooling—preventing catastrophic failure. These features protect sensitive PLCs, I/O modules, and network switches from damage due to field wiring errors or transient grid disturbances.

Compact footprint with high power density: Despite delivering 120 W, the PACIFIC 6445-001-K-N occupies just 45 mm of DIN rail width—enabling high-density power distribution in control panels with limited space. Its low-profile depth (115 mm) also avoids interference with rear-mounted terminal blocks or backplanes, a common issue with bulkier legacy supplies.

Application Field

The PACIFIC 6445-001-K-N is commonly deployed in industrial control cabinets across oil & gas, water/wastewater, packaging, and material handling systems. In upstream oilfields, it powers RTUs and safety relays in remote wellhead control panels where ambient temperatures fluctuate dramatically and maintenance access is limited. Its fanless design prevents sand or salt ingress from compromising performance—critical for offshore platforms or desert installations.

In municipal water treatment facilities, the PACIFIC 6445-001-K-N supplies clean, ripple-free 24 V DC to level transmitters, motor starters, and SCADA I/O modules. The unit’s immunity to voltage dips ensures pumps and chemical dosing systems remain operational during grid instability. Similarly, in automated bottling lines or conveyor systems, the PACIFIC 6445-001-K-N provides stable power to photoelectric sensors, solenoid valves, and small PLCs—minimizing unplanned downtime caused by power-related glitches.

Many legacy automation systems originally equipped with older linear or unregulated supplies are retrofitted with the PACIFIC 6445-001-K-N to improve efficiency and reliability. Its pin-compatible mechanical and electrical interface allows drop-in replacement without rewiring, making it a cost-effective upgrade path for aging infrastructure still in productive service.
