Allen-Bradley 150-F780JHE SMC-Flex Solid State Controller 780A

Product Overview

The Allen-Bradley 150-F780JHE is a solid state controller from the SMC-Flex series, designed for demanding motor starting and protection applications. With a robust IP54 (Type 12) enclosure, this unit withstands harsh industrial environments while delivering a controller rating of 780 A and 600 Hp @ 460V AC. It operates on a 200-208V AC, 3-phase input line at 50 and 60 Hz, making it suitable for global installations. The control voltage is 110/120V AC for 625-1250 A units, ensuring compatibility with standard control systems.

Technical Specifications Breakdown

Key parameters for the 150-F780JHE are listed below for quick reference:

Industry Applications

Its 780 A rating supports large induction motors up to 600 Hp at 460V AC, reducing inrush current and mechanical stress. Compared to lower-rated models, the 150-F780JHE offers higher current capacity without sacrificing protection, providing a cost-effective solution for high-power applications.

Installation & Setup Guidance

Mount the controller on a flat, vertical surface to ensure proper cooling. Verify that the input line voltage matches the 200-208V AC, 3-phase supply. Use appropriately sized copper conductors rated for the 780 A continuous current. The control voltage must be 110/120V AC for the control circuit. Ensure all connections are torqued to manufacturer specifications and that the enclosure door is sealed to maintain IP54 integrity.

Maintenance & Reliability

Periodically inspect the enclosure seals and cooling fans for debris. Check all power and control connections for signs of overheating or corrosion. The IP54 rating protects against dust and water splashes, but avoid high-pressure washdowns. Schedule annual thermal imaging scans to detect loose connections early.

Compatibility & Integration

The SMC-Flex series integrates with Allen-Bradley PLCs via standard discrete I/O or optional communication modules. The 150-F780JHE is compatible with SMC-Flex soft starter accessories such as bypass contactors and overload relays. Use the same control voltage (110/120V AC) for consistent system design.

Selection Guide & Purchasing Advice

When selecting a solid state controller, match the full-load current of your motor to the controller rating. For lower horsepower, consider smaller SMC-Flex models. AutoDCSTech stocks this unit and can advise on lifecycle status and availability. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

If the controller fails to start, verify input line voltage (200-208V AC) and control voltage (110/120V AC). Check for tripped overloads or blown fuses. Overheating may indicate blocked ventilation or excessive ambient temperature. For persistent faults, consult the SMC-Flex user manual for diagnostic codes.
