Product Description:
The 131B5661 Frequency Converter delivers a rated shaft output of 4.0 kW (5.0 HP) at 460 V. It is designed for use in industrial installations with both panel and wall/floor mounting options. The unit provides efficient motor control and constant torque operations.
The Danfoss 131B5661 frequency converter features chassis type A2 with IP20 protection. Under continuous load at 3 x 380 – 440 V, it delivers an output current of 10 A and 8.2 A at 3 x 441 – 480 V. The intermittent current levels are rated at 11 A and 9.0 A respectively. The power ratings of this converter include 6.9 kVA at 400 V and 6.5 kVA at 460 V. The converter handles an estimated power loss of 124 W at full rated load which contributes to overall energy efficiency. The starting torque and overload torque for variable torque applications are both supported up to 110 % for 60 seconds. The input current (continuous) reaches 9.0 A for 3 x 380 – 440 V and 7.4 A for 3 x 441 – 480 V. The unit supports a torque rise time of 10 ms under VVC⁺ control that ensures fast torque response in dynamic applications. The vibration resistance of this model is rated at 1.0 g. The unit performs reliably in environments with relative humidity ranging from 5 % to 93 % (non condensing).
The ambient operating conditions of the 131B5661 frequency converter support full scale performance from 0 °C and reduced performance from - 10 °C. The storage and transport temperatures range from - 25 °C to + 65/70 °C. The converter is certified for installation on walls, floors or inside panels bolted to structural surfaces. The converter’s overload capability for constant torque operation also reaches 110 % for 60 seconds. The architecture of this model supports consistent performance under both light and demanding load conditions.
