Product Description:

The Danfoss 131B0402 Automation Drive comes with a rated capacity of 1.25 kVA to provide regulated power for applications with reliable output. It has a frame size A2 that offers a miniaturized structural profile, making it ideal for installations where limited panel space is a prominent consideration.

This drive is designed with an output current of 1.6 A to provide reliable compatibility with motor loads running under specified current ranges. For better system reliability, it features a power backup capability through the use of the MCB-107 24V DC module, keeping control functions stable during power shutdown. This automation drive works using a power supply frequency of 50/60 Hz ±5% and can be used flexibly in regions with varying power grid standards. The gross weight of this drive is 5.436 kg, which indicates a solid and easy-to-manage construction for enabling uncomplicated integration into equipment cabinets. Its displacement power factor of greater than 0.98 indicates close-to-unity efficiency, reducing reactive power losses and promoting maximum system energy performance. The 131B0402 drive has a dissipation energy of 42 W to ensure balanced heat production for minimizing thermal overload risk under long-running duty cycles.

This automation drive features two programmable pulse inputs. Each of these inputs provides 0.1% of full-scale accuracy to allow high accuracy in process measurement. For communication, this drive features a PROFIBUS DP MCA 101 interface. This interface ensures a reliable networked operation for fast exchange of control data with automation controllers. This automation drive has an overload handling capacity of 160% at 0.55 kW, which enables the handling of short-duration excess loads safely. The 131B0402 drive features an RFI Class A1/B (C1) EMI filter that efficiently minimizes electromagnetic interference and helps to ensure industrial noise standards compliance.
