Frequency Converters
SENTINEL XR PLUS
Sentinel XR Plus is the ideal solution for frequency conversion. For this series models are available from 5kVA-10kVA single / single phase and 6.5 kVA - 10kVA single phase / three phases. The load is powered continuously by the inverter with a sinusoidal voltage and is filtered in the form of voltage and frequency stabilized. The input and output filters increase the immunity of the load against mains failure.
HIGH QUALITY OF THE OUTPUT VOLTAGE
• Even in non-linear loads (computer science loads with crest factor up to 3:1)
• Very high overload capacity: 150% as an inverter
• filtered, stabilized and reliable voltage
FEATURES
• Frequency conversion 50 Hz or 60Hz
• Output power factor 0.8
• Autorestart (automatically at power, programmable via software or manually)
• Advanced communications
• Standard recovery protection
• RS232 interface
• Inclusive software for monitoring and controlled shutdown of the connected systems
FLEXUS FMH
The series Flexus is an ideal frequency converter for 50Hz or 60Hz. The series Flexus FM is available in the model versions 10, 12, 15 and 20 kVA three-phase output and input phase or single phase. The development and production of Flexus is done with technologies and components in up to date technology in order to guarantee maximum protection of the connected equipment.

SENTRY MPS FC
Sentry MPS FC is a series of frequency converters based on the Sentry MPS UPS that can accept 50/60Hz and deliver a 400Hz output. The device has a double conversion design with a transformer-isolated inverter.
The output voltage is 208VAC and configurable at 200VAC on site with a 115VAC version available on request.
The basic design is a solid state generator with an IGBT - based Inverter controlled using PWM techniques. It is ideal for applications such as avionic repair workshops, hangars, aircraft ground power in civil airports and military bases.
FEATURES
• Easy source
• Low distortion of the input voltage of up to 5 % and power factor of up to 0.93
• Compatibility with the motor generator thanks the functions as power walk-in and power walk-in delay timer
• Isolation transformer on the inverter that protects the load from mains interference in all operating conditions
• Thermal overrating of the inverter to guarantee an overload (kVA) at 110% for 60 minutes
