Product Description:

The HVAC Drive with product code 131F6630 is designed and engineered by Danfoss. This drive resists 5%–93% relative humidity, according to IEC 721-3-3, Class 3K3 (non-condensing) specifications.

The 131F6630 drive accommodates a peak input intermittent current of 64.9 A, which enables it to easily manage high starting requirements. Its efficiency is maximized with an energy efficiency rating of 0.98, reducing power loss over the duration of use. Its ramp-up profile is tailored within a 1 to 3600 sec operating range, allowing operators to choose accurate ramping times to meet application-specific startup requirements. This HVAC drive operates between -10 °C and +50 °C to provide guaranteed operation across diverse climatic conditions. This drive incorporates two analog inputs with a maximum error precision of 0.5% full scale, offering reliable measurement consistency for signals in HVAC applications. In addition to analog inputs, this drive features six digital inputs to ensure suitability with diverse control logic. For enhanced configuration, this drive also includes two programmable relay outputs, which allow connection to auxiliary devices or system alarms with adaptable settings.

Its sustained operation is facilitated with an output current of 73 A at 380–439 V, ensuring consistent motor performance under rated conditions. The standard shaft output of this HVAC drive is 37 kW, which makes it ideal for medium-to-large HVAC applications. At full rated operation, there is an estimated power loss of 739 W, giving precise data for efficiency and thermal management evaluation. Its structure is also durability tested by its vibration resistance of 1.0 g, guaranteeing stability at the time of installation in mechanically vibrating or moving locations. The physical weight of the 131F6630 drive is 22.14 kg, which balances its size and output strength, and facilitates easier planning for installation.
