At Wallco Inc., we offer high-performance ACME Drive Isolation Transformers designed to protect Variable Frequency Drives (VFDs) from power line disturbances and short-circuit conditions. By electrically isolating the incoming power from the drive circuitry, these transformers ensure smoother operation, improved reliability, and extended life of three-phase motors.

ACME transformers provide vital voltage conversion while minimizing electrical noise and disturbances caused by SCR (Silicon Controlled Rectifier) firing, making them essential in industrial environments where VFDs are used to precisely control motor speed.

Features

• Designed for use with VFD to protect them from line disturbances
• kVA ratings from 7.5 through 990 kVA to support your most common applications
• Designed for overcurrent of up to 150% for 60 seconds or 200% for 30 seconds to handle demanding applications.
• NEMA 1 enclosures with optional weather shields for indoor or outdoor protection
• Aluminum winds are standard for a cost-effective solution
• UL and cUL certified to meet your local requirements
