The 1361-NO61-2-5 is an Allen-Bradley drive isolation transformer featuring a 5.0 kVA power rating and a NEMA Type 1 enclosure for indoor protection. This model is specifically configured for a 230V AC primary and 575V AC secondary voltage transformation, utilizing grain-oriented silicon steel cores to ensure efficient electrical performance within a compact footprint.
Electrostatic Copper Shielding
Class 180 (H) Insulation
NEMA Type 1 Enclosure
This transformer incorporates an electrostatic copper shield between the primary and secondary windings to attenuate high-frequency line noise and protect sensitive drive logic from transients. It is engineered with a Class 180 (H) insulation system to withstand the harmonics and non-linear loads of solid-state motor controllers, supporting a 115°C or 150°C temperature rise over standard ambient conditions.

Motor Drive Systems
Used to provide electrical isolation and voltage matching for AC and DC variable speed drives. The electrostatic copper shield attenuates high-frequency noise and protects the drive's sensitive microprocessor logic from line-side voltage transients.
Precision Manufacturing
Applied in automated assembly lines where sensitive electronic controllers require protection from ground loops. The Class 180 (H) insulation system is engineered to handle the non-linear loads and harmonics generated by solid-state power conversion equipment.
HVAC Control Systems
Implemented in large-scale commercial building management to isolate variable frequency drives (VFDs) used for fans and pumps. It ensures that switching noise from the power transistors does not migrate back into the building’s main electrical distribution system.
Water Wastewater Treatment
Utilized in pumping stations to provide a dedicated secondary power source for motor controllers. The NEMA Type 1 enclosure provides a degree of protection against incidental contact with internal components in indoor control room environments.
Industrial Automation Cells
Deployed in robotic workcells and CNC machining centers to stabilize voltage levels for precision motion control. The grain-oriented silicon steel core design ensures high efficiency and reliable performance under continuous-duty operating conditions.
Food Processing Plants
Used in conveyor systems and packaging machinery to isolate the drive electronics from the plant's power grid. Its dual 50/60 Hz frequency rating allows for international equipment standardization across different geographical power standards.
The 1746-NR4 module is identified as a specialty I/O module and should not be installed in a slot adjacent to AC or high-voltage DC I/O modules or the system power supply to avoid electrical noise interference. For all RTD or resistance inputs, use shielded twisted-pair cable with the shield grounded at the SLC chassis end only to prevent ground loops and ensure the highest noise rejection by selecting an input filter frequency that matches the AC line frequency. To maintain specified accuracy across the entire operating temperature range without manual adjustment, the module performs an autocalibration cycle upon power-up and at periodic intervals during operation.
Furthermore, the 1746-NR4 provides continuous diagnostics for open-circuit and short-circuit conditions and can be configured to measure direct resistance in ranges up to 3000Ω, allowing for interfacing with non-standard resistance-based sensors or linear potentiometers.
