Product Description:
Danfoss manufactures the control drive 134L5912 in accordance with the product specification code FC-102P3K0T2E55H2XGCXSXS009XAXBXCXXXXDX for precise motor control in HVAC systems. It is rated for 3.0 kW shaft power at 208 V operation and it delivers a nominal output current of 12.5 A, while its intermittence current reaches 13.8 A for a brief time of 60 sec.
The 134L5912 drive possess an overload capacity of 110% for one minute within ten minutes and its input voltage range is 3 x 200 to 240 VAC at 50 or 60 Hz. Its gives efficiency up to 98% in normal duty and 155 W of typical estimated power loss. The unit’s switching frequency is adjustable up to 16000 Hz and its ramping time can be set up to 3600 s. Its maximum output frequency extends up to 590 Hz for motor applications and its environmental protection is ensured with IP55 as well as through UL Type 12 enclosure. The 134L5 drive provides six digital inputs supporting 0 to 24 VDC signals and its input resistance is approximately 4000 Ohms, with scan times of 5 ms. Its 2 digital inputs allow pulse operation with 0.1 to 1 kHz range and 2 digital outputs are rated at 24 VDC at 40 mA maximum. The unit’s relay outputs are rated at 240 VAC and 2 A for switching.
The 134L5912 drive relies for communication on embedded protocols that include BACnet MS TP, Modbus RTU, Johnson N2 and Siemens FLN protocols. Its protective functions include thermal monitoring of motor windings and short circuit, along with ground fault protections that are integrated on motor terminals. Its vibration tolerance is around 0.7 g and it comes with graphical screen interface of LCP 102.
Frequently Asked Questions about 134L5912:
Q: How does the adjustable switching frequency benefit motor performance in the 134L5912?
A: A higher switching frequency allows smoother motor operation with reduced audible noise and lower harmonic distortion, improving overall system comfort. It also enables more precise control of motor torque and better response in variable-load scenarios.
Q: Why is the 110 % overload capacity for one minute within ten minutes useful in the 134L5912?
A: It allows the drive to handle temporary load surges without tripping, ensuring reliability during peak demands such as startup or transient conditions. This prevents unnecessary shutdowns in HVAC systems where brief overloads are common.
Q: What is the advantage of having analog inputs with both voltage and current ranges in the 134L5912?
A: Its dual ranges (0-10 V or 0/4-20 mA) accommodate various sensor types and control sources without needing external converters. For 134L5912, it increases flexibility when integrating with different building management systems or legacy controls.
Q: How does the relay output rated at 240 VAC, 2 A improve control logic in 134L5912?
A: It allows the drive to directly operate external devices like contactors or alarms without requiring separate relays, simplifying wiring. In 134L5912 systems, this ensures tight coordination between drive status and external safety or feedback elements.
Q: What is the benefit of having 2 digital inputs for pulse operation (0.1–1 kHz) in the 134L5912?
A: The pulse inputs allow precise speed or position control, such as from external tachometers or encoder signals, enabling closed-loop or quasi-closed-loop control without full feedback loops. This feature boosts responsiveness for fans or pumps driven by the 134L5912.
