Product Description:
The 175H2912 Variable Speed Drive is engineered by Danfoss, and it requires a three-phase supply voltage for operation. This drive provides a rated output power of 11 kW, which is appropriate for medium industrial loads where consistent drive performance is a requirement.
This drive functions with an input voltage range of 380–415 V, with a tolerance of ±10% to offer compatibility with commercial electric systems. It facilitates an input switching frequency of 2 times per minute to guarantee a controlled operational frequency for system startup and shutdown cycles. This drive demands a maximum pre-fuse rating of 50 to meet the safety needs of electrical protection against overload and abnormal current conditions. The 175H2912 drive has a power factor of 0.9/1.0 to maintain effective electrical performance while optimizing energy under changing industrial operating loads. Its operating transparency is enhanced with specific indicator LEDs of Alarm and ON states, allowing for immediate identification of operational status and fault conditions. It provides an adjustable output frequency range of 0 to 120 Hz for accurate adjustments according to various motor needs in different application situations. The ramp times of this drive can be configured by the users between 0.1 and 3600 seconds to produce smooth acceleration and deceleration ramps.
The 175H2912 drive features a maximum input current of 22 A for stable electrical operation while offering consistent performance under rated loads. Its electrical connectivity supports 6 AWG maximum cable cross-section for secure wiring installations and safe current handling in tough environments. This drive’s mechanical robustness is enabled by vibration conformity of 0.7 g for reliable operation in environments with mechanical movement or vibration. This drive favors ambient storage and transport temperatures between -30 °C and +70 °C, to provide stability in handling, shipment, and non-operational modes.
Frequently Asked Questions about 175H2912:
Q: How does the adjustable ramp time feature in the 175H2912 improve motor operation?
A: Adjustable ramp times reduce mechanical shock by controlling acceleration and deceleration. This helps extend motor lifespan and prevents stress on connected mechanical systems.
Q: Why is the vibration conformity of 0.7 g important for the Danfoss 175H2912?
A: It ensures reliable function in environments with mechanical vibrations. This is crucial for industrial setups where equipment movement or heavy machinery is present.
Q: What role do the Alarm and ON indicator LEDs serve in the 175H2912 drive?
A: These LEDs provide immediate operational status feedback. They allow quick troubleshooting and minimize downtime by highlighting issues before they escalate.
Q: How does the input switching rate of 2 times per minute support safe operations?
A: It limits frequent switching to reduce stress on electrical circuits. This ensures safer handling of power loads and prevents premature component wear.
Q: Why does the Danfoss 175H2912 include a ±10% voltage tolerance in its design?
A: The voltage tolerance accommodates fluctuations in industrial power supply. This ensures the drive maintains stability and consistent performance despite grid variations.
