MeloAuto-Trusted PLC & DCS Parts Supplier
The 51404170-175 power supply module feeds regulated DC voltage to Honeywell TDC 3000 control cabinets. This unit converts incoming AC line power into stable backplane current for connected boards. Plant engineers rely on its steady output through long production runs.
Output Ratings and Component Count
The 51404170-175 delivers 15 A at +5 VDC to the card file backplane. It also provides ±12 VDC auxiliary rails for analog circuit support. The assembly carries 58 discrete components, including 6 filter capacitors and 4 rectifier stages. Additionally, 2 cooling fans keep internal temperatures within safe limits.
Physical Dimensions and Weight
This module measures 14.0 inches in length and 8.0 inches in width. Module height reaches 4.5 inches, while the unit weighs approximately 6.8 pounds. These dimensions fit standard TDC 3000 power chassis bays directly. Consequently, technicians swap units quickly during planned maintenance outages.
Interface, Protection, and Energy Storage
Four terminal blocks handle AC input and DC output distribution. The 51404170-175 provides 1500 VAC isolation between input and output circuits. Two internal capacitors store enough energy to ride through brief line sags. Therefore, the module keeps logic boards running during short power disturbances.
Input Requirements and Thermal Parameters
The unit accepts 120/240 VAC input at 50/60 Hz with automatic range selection. Operating temperature ranges from 0°C to 50°C under full load. Overvoltage and short-circuit protection circuits guard downstream boards from damage. Meanwhile, efficiency stays above 85% at rated output.
