Product Description:

The HVAC Drive 131B6126 by Danfoss provides accurate operation in various air handling and building control systems. The housing of this drive is Type 12 / IP 55, which protects it from dust entry and exposure to low-pressure water.

This drive has a B1 frame size to enable compact installation for integration into small control panels or equipment enclosures. This drive has a standard output of 15 kW to be suitable for medium-load HVAC applications. The power saving of this drive is ensured by an efficiency of 0.98, which enables maximum electrical power to be realized as mechanical power. At full demand, the approximated power loss by this drive is 392 W, thus reducing waste heat production and enhancing operational equilibrium. When short-term load spikes happen, the 131B6126 drive tolerates an output intermittent current of 29.7 A to allow short-term flexibility under challenging applications. This HVAC drive’s 25 A input current matches system needs with efficient reliability and electricity stability. This HVAC drive operates efficiently between a relative humidity level of 5% to 93%. It conforms to IEC 721-3-3 Class 3K3 non-condensing standards to remain functional in changing atmospheric conditions.

With a rated voltage range of 440–480 V, it provides a continuous output current of 27 A to guarantee consistent operation under long-term usage. This drive’s status visibility is provided through three LED indicators, which symbolize On, Warning, and Alarm modes. These indicators present instantaneous diagnostic data, enhancing the operational awareness and efficiency of system maintenance. The 24.35 kg gross weight of the 131B6126 drive provides equilibrium between structural stiffness and convenient handling for transport and installation. This drive also has two integrated analog inputs for compatibility with control systems that demand direct analog signaling.

Frequently Asked Questions about 131B6126:

Q: How does the efficiency of 0.98 in HVAC Drive 131B6126 improve performance?

A: The high efficiency rating ensures minimal energy loss during operation. This allows more input power to be converted directly into useful output.

Q: Why is vibration conformity of 1.0 g significant in this product?

A: It allows the drive to operate reliably in environments with mechanical stress. This helps prevent performance degradation caused by constant vibration.

Q: What benefit do the two analog inputs in the HVAC Drive 131B6126 provide?

A: They enable integration with external controllers for flexible system management. Users can connect multiple signals for better process control.

Q: How do the three LED indicators improve drive usability?

A: The LEDs provide clear status updates of On, Warning, and Alarm. This reduces troubleshooting time and improves safety awareness.

Q: Why is the casing type IP 55 important for the HVAC Drive 131B6126?

A: It ensures the unit is protected against dust and water ingress. This allows use in challenging environments without risk of internal damage.
