IGBT rectifier
Type GR-3864
Bidirectional rectifier with TFT display
With our IGBT rectifiers, modern power supply solutions are realised taking into account low THDi values and energy efficiency (low apparent power consumption, regenerative).
Equipment
- Regenerative IGBT rectifier
- Low ripple (<0,5%)
- Low mains feedback due to PFC
- Systems can be connected in parallel
- Input contactor for rectifier
- Automatic charge
- Programmable battery test with full nominal power through mains regeneration
- Analogue control
- Microprocessor-controlled monitoring
- Digital display with event ring memory (non-volatile); colour TFT panel with touch screen
- Power unit with two-stage temperature monitoring
- Galvanic isolation between input and output
- 8 remote signals (potential-free contacts, configurable)
- RS232
State of the art
- High MTBF values
- Power factor input at nominal power >0,99
- Total harmonic distortion THDi < 6 %
- User-friendly, intuitive operation
- Temperature-controlled charging voltage
- 3 Charging characteristics IU (Automatic)
- Design according to current standards
Options
- Temperature controlled charging voltage
- Earth fault monitoring
- Profibus, Modbus, SNMP and other interfaces
- Increased protection class (e.g. IP21)
- Further options on request
