Product Description:
The 178F0665 Low Voltage Drive is the product of Danfoss that has been tested to withstand oscillations or mechanical shaking up to 0.7 g which indicates a robustness against environmental vibration. The rotating output available to the driven machine corresponds to 1.5 kilowatts of usable mechanical power.
The 178F0665 low voltage drive can safely endure fault current of 100,000 amperes at the supply unit without being destroyed which represents the peak fault capacity of the drive's input circuitry. The modules' weights a little over 2 kilograms which makes it relatively lightweight and simple to handle, install or mount. Its line inputs can be switched on or off no more than twice in a sixty second period which protects the power electronics inside from repeated stress caused by frequent energizing and de energizing. When it is fully loaded, the ratio of real power delivered to apparent power is about 90 percent which means it has reasonably good efficiency in converting electrical energy into useful mechanical work. It can deliver a turning force that is one and a half times greater than its rated torque for a short duration of sixty seconds.
This VLT 2800 Low Voltage drive can function in environments with very low value up to 5% to very high air humidity up to 93% as long as it does not condense. It has an ambient thermal limit of 45 °C for operation but the average over twenty four hours should not surpass forty. It is able to deliver up to 2.6 kVA of apparent power when it is powered from a four hundred volt supply. It provides an RMS output current of approximately 3.7 amps to the connected motor under nominal conditions.
Frequently Asked Questions about 178F0665:
Q: How does the 178F0665 Low Voltage Drive handle frequent supply switching?
A: It is limited to a few reconnections per minute to prevent thermal and electrical stress. This extends component life and ensures stable input conditions.
Q: What happens if supply voltage imbalance exceeds tolerance?
A: Excessive imbalance can cause overheating in motor windings and uneven torque. The drive compensates slightly, but performance and efficiency drop outside limits.
Q: Can the 178F0665 Low Voltage Drive be installed in high-humidity environments?
A: Yes, as long as condensation is avoided to protect electronic boards. Proper enclosure rating or cabinet ventilation may be required in humid regions.
Q: How does high starting torque capability benefit motor-driven systems?
A: It helps start heavy-load machinery like pumps or conveyors without stalling. This reduces the need for oversized motors or mechanical soft starters.
Q: What impact does its power factor have on facility power quality?
A: A near-unity power factor lowers reactive current draw from the grid. This minimizes utility penalties and reduces transformer loading.
