FH Portable PM Operator Box
Product Overview
Permanent Magnetic Actuator (PMA) System with Portable Operating Box
Powerful. Reliable. Portable.
The operating energy for the permanent magnetic actuator (PMA) is supplied by energy-storage capacitors. Our Portable PMA Operating Box ensures fail-safe operation of PMA switches even during secondary control system failures, enabling manual open/close operations when needed.
Key Features
- Compact & Lightweight – Easy to carry and store
- Sleek Design – Durable and user-friendly
- High Reliability – Minimal components, maximum uptime
- Dual Backup Power Options – Supports battery (DC) or hand-crank generator
- Essential for Power Utilities – Ensures uninterrupted operation and improved power supply quality
Universal Compatibility
Works with both single/double-coil PMA switches (monostable & bistable)
Seamless replacement for failed PMA drive circuits – manually open/close breakers during control system failures
Compact & Field-Ready Design
Ultra-lightweight (easy to carry) + ergonomic shoulder strap for hands-free portability
Fits in toolkits – ideal for substation/field maintenance
Enhanced Safety & Reliability
Integrated capacitor discharge circuit
Ensures fast, safe discharging
Extends capacitor lifespan by preventing overvoltage damage
Coil health monitoring
Dedicated test ports for multimeter-based coil diagnostics (detect open/short circuits)
