Product Description:
The 131B0845 Frequency Converter is a compact and efficient drive designed for industrial applications. It operates with a three phase supply voltage between 380 VAC and 500 VAC.
The 131B0845 frequency converter by Danfoss delivers an output power of 5.5 kW or 7.5 HP. Its chassis is built with IP20 protection for safe installation. The product integrates a brake chopper, graphical local control panel and a coated printed circuit board. These features ensure reliable performance and extended service life in challenging environments. The frequency converter also includes RFI Class A1/B and C1 compliance for electromagnetic compatibility. The drive is engineered with strong electrical and mechanical specifications. The frequency converter offers a continuous current of 13 A and an intermittent current of 20.8 A under high overload operation. The rated apparent power is 9.01 kVA with a calculated power loss of 187 W. The converter measures 268 mm in height, 130 mm in width and 205 mm in depth. The gross weight of the model is 7.716 kg that makes it compact for its output rating. The system supports a power rating of 160 % at 5.5 kW for heavy loads.
The 131B0845 frequency converter also includes a control card with + 10 V DC output. The card has an output voltage of 10.5 V ± 0.5 V and a maximum load of 25 mA. The control performance of this converter is precise with a frequency resolution of ± 0.003 Hz across the 0 – 1000 Hz range. The speed control range in open loop is 1:100 of synchronous speed while the speed accuracy in open loop is maintained at ± 8 RPM from 30 to 4000 RPM.
Frequently Asked Questions about 131B0845:
Q: How does the Danfoss 131B0845 frequency converter maintain stability during speed regulation in open loop mode?
A: It delivers ±8 RPM speed accuracy between 30 and 4000 RPM with a 1:100 control range. This ensures consistent output even without encoder feedback in variable speed operations.
Q: What should be considered when sizing control signals for the 131B0845 frequency converter’s integrated control card?
A: The card provides a +10 V DC output with a tolerance of ±0.5 V and supports up to 25 mA load. This allows safe interfacing with external analog devices like potentiometers.
Q: How does the 131B0845 frequency converter respond to rapid load variations in high-demand cycles?
A: It supports heavy-duty overload handling with up to 160% of rated power. This delivers strong torque response during sudden load spikes without performance loss.
Q: What integration advantages does the Danfoss 131B0845 offer for EMC-sensitive industrial environments?
A: It includes built-in RFI filters compliant with Class A1/B and C1 standards. This reduces conducted emissions, making it suitable for installations with strict electromagnetic compatibility requirements.
Q: How does the chassis design of the 131B0845 converter support long-term durability in control cabinets?
A: Its IP20-rated enclosure and coated PCB protect against dust and humidity. The integrated brake chopper and graphical panel simplify setup while enhancing thermal and functional reliability.
