Product Description:
The 131X0848 drive is produced by Danfoss according to the product code FC-302PK37T5E20H1BGXXXXSXXXXALBXCXXXXDX as a three-phase frequency converter. It has an IP 20 rated chassis that allows it fit into a typical industrial setting with ease and its size measures 26.8 cm in height and 9.0 cm in width and 20.5 cm in depth, though alternative options have a depth of 22.0 cm.
The 131X0848 drive has a nominal power rating of 0.37 kW at 400 V AC and its input voltage is between 380 - 500 V AC. It is designed for continuous operations with a rated continuous current of 1.2 A and a peak periodic current of 1.9 A. The unit’s apparent power rating is 0.9 kVA to ensure efficient performance while consuming minimal energy and its power loss value at rated full load is specified as 35 W. It possesses an efficiency of 160% at maximum load rating and for electromagnetic compatibility, the drive features a class A1/B RFI filter to keep interference to a minimum level in sensitive applications. The drive includes a brake-chopper for safe stopping functionality to ensure the system operates with minimal risk in case of power failure.
The 131X0848 drive features IGBT braking for safe functionality and its graphical presentation is through an LCP 102 panel for easy monitoring and diagnostics. It comes with standard cable entries and does not include any mains power options. The drive possesses 2 programmable relay outputs, with NO and NC points that supports load of 2 A at 240/400 V AC and at 24 VDC it supports up to 20 mA. Its software is up-to-date with the latest version of the standard package and supports a standard language pack.
Frequently Asked Questions about 131X0848:
Q: How does the brake chopper in Danfoss 131X0848 protect the motor during stopping?
A: The brake chopper dissipates excess energy from deceleration by directing it into a resistor, preventing voltage spikes. It ensures safe and swift stopping, protecting both the IGBTs and the motor windings.
Q: What role does the RFI filter class A1/B serve in the 131X0848 drive?
A: It reduces electromagnetic interference transmitted back to the power lines and nearby equipment. This compliance helps in sensitive industrial settings and meets EMI standards.
Q: Why would one choose the 131X0848 model over a standard entry-level VLT drive?
A: The 131X0848 offers expanded motion control, higher I/O flexibility, and better dynamic response. It is well-suited for applications needing synchronization or positioning under varying loads.
Q: What is the benefit of having 2 programmable relay outputs in 131X0848?
A: The users can configure relays for fail-safe, alarm, or process-status signaling based on custom conditions. This enhances integration with safety or monitoring systems without extra hardware.
Q: How does the steady current versus peak periodic current specification in 131X0848 matter for motor sizing?
A: The nominal current (1.2 A) must match the motor’s continuous rating to avoid overheating. The peak current (1.9 A) defines how much transient load or torque the system can handle without tripping or damage.
