SEMI F47 Low Voltage Ride Through Module
Minimize voltage sags and increase machine uptime

By ensuring SEMI F47 compliance of AC powered IEC contactors and relays, TELEMECANIQUE Low Voltage Ride Through Modules can be used to increase the voltage sag immunity of semiconductor processing equipment. These modules make it possible for AC powered TELEMECANIQUE contactors and relays to exceed the requirements of SEMI F47. Low Voltage Ride Through Modules can be used with TELEMECANIQUE contactors 9A through 80A, as well as the CAD series of control relays.

Key Benefits

• Easy retrofitting. Modules are compatible with TELEMECANIQUE contactors 9 A through 80 A and CA2 series control relays.
• Reduced inventory. Each module covers complete contactor amperage range.
• Increased flexibility. Available in 24 VAC, 120 VAC and 208 VAC versions.
• Unsurpassed operation and performance. Electronics and 8-bit micro-controller optimized to TELEMECANIQUE contactor and relay coils.
  • Overvoltage protection during coil energization
  • Level 4 surge and fast transient burst
• Uses 8-bit micro controller. Micro-controller helps discern between 20 ms micro outages and activation of EMO button for emergency shutdown.
• Exceeds SEMI F47 ride through standards. Guaranteed ride through at 45% of nominal voltage, with no restriction on voltage sag duration, and drop out at 30% of nominal voltage.
• Meets industry standards. Modules carry UL, IEC, CE mark. Also, certified SEMI F47 compliant by EPRI PEAC.
• Easy installation. Modules mount directly to the top of contactors and relays - no wiring required.
