CONVOY MF33 series 10~120KVA low frequency UPS is transformer based, fully digital, online double conversion, highly intelligent UPS which integrate digital control, information technology, network connectivity. With powerful information gathering system, signal processing system and full protection system, It offers perfect sine wave output which suits all kinds of load. With digital architecture and abundant options which you can customize specially for your needs, CONVOY MF33 series provide all kinds of power protection to your investment.
Online Double Conversion, complete isolation between load and Grid/Generator Zero phase shift output isolation transformer based. Superior overload capacity. Minimize the neutral to earth voltage and load harmonic current to protect inverter. Powerful capacity to handle 100% unbalanced load.
High rated output power factor 0.9, deliver more real power
High input power factor 0.95 (with filter), lower pollution
Fully digitally controlled by dual DSP, more stable and reliable
Wide input voltage tolerance (±25%)
Wide input frequency range (45~65Hz)
superior overload capacity and short circuit capacity (5s) to ensure system stability and safety under extreme harsh condition.
Temperature compensation function Battery discharge time assessment, periodic self detection
Battery switch status gathering, detection and control
Up to 6 cabinets direct paralleling, no need centralized bypass cabinet
LBS (Load Bus Synchronization) enable two independent UPS systems to form Dual Bus Architecture for higher reliability
Power Walk In function lower down the inrush current of system start, so to minimize the requirement for generator capacity
Automatically adjust fan speed according to inside temperature and load rate to obtain lower noise, longer fan life and less energy consumption
Start the UPS into battery (charged) mode directly, convenient operation option for user
The UPS can be programmed to auto restart after invert shutting down when the battery reaches EOD (End of Discharging)
IGBT based SVPWM inverter. Power devices built in rectifier, static switch and inverter are equipped with independent dissipaters. Combine with front access design, make installation and maintenance easier
ARM controlled large LCD (7 inch TFT for 30KVA and above) provides real time UPS operating tatus and parameters information in bilingual
Self-diagnose when starting Full software and hardware protection (short circuit, inverter overheat, battery voltage low & high, surge)
Normal mode, Battery mode, Bypass mode, Maintenance mode, Auto-restart mode, Source Share mode, ECO mode, Frequency converter mode
Standard: R232/R485, Optional: SNMP/JBUS/MODBUS/Dry contact card. Flexible connectivity for real time management.
