Product Description:
This Danfoss 175U3310 Brake Resistor is made to provide superior durability and reliability in harsh conditions. It has resistance tolerances of 10% and a dielectric strength of 2500 V AC in 1 minute and provides steady operation at high voltage conditions. It is resistant to multiple operating environments and it is an efficient product in situations demanding a consistent power supply and strong insulation.
The 175U3310 resistor is engineered to handle extreme conditions with outstanding efficiency and performance. It sustains constant power load of 450 W at full load and is reliable in terms of long term operation. It can also operate pulse load power to 5 kW at a 40 percent duty cycle, which is appropriate in applications where the high power must be used only in peaks. The module is compatible with a broad set of environmental conditions with a maximum temperature of 300 C on the housing, which offers impressive protection against heat. It is also stable in environments with relative humidity of 5-85 percent without exposure to condensation, which is why it is suitable in diverse industrial environments. Moreover, the presence of a temperature switch contributes to an additional protective measure, which can prevent excessive heating. The product is constructed to withstand dust and water ingression, with an IP54 rated wire which is less prone to failure in harsh environmental conditions.
This 175U3310 resistor is built with superior insulation, boasting an impressive 20 MΩ resistance at 1000 V. Its resistance of 410 ohms gives it consistent stable performance in a wide range of applications. It also supports derating at high altitudes and maintains 100 percent up to 1000 meters above sea level.
Frequently Asked Questions about 175U3310:
Q: How does the 175U3310 Brake Resistor handle pulse load power?
A: It supports pulse load power up to 5 kW with a 40% duty cycle. This makes it ideal for applications requiring high power only in short bursts.
Q: What is the significance of the IP54 rating for the wire?
A: The IP54 rating ensures the resistor's wire is protected against dust and water ingress. This makes it suitable for use in environments where exposure to moisture or dust is a concern.
Q: How does the resistance tolerance of ±10% affect the 175U3310’s performance?
A: The resistance tolerance impacts the accuracy of power dissipation. Variations within this range can affect the efficiency, but it remains within acceptable limits for most industrial applications.
Q: How does the insulation resistance of > 20 MΩ improve safety?
A: This high insulation resistance ensures minimal leakage current, protecting sensitive equipment from electrical faults. It also enhances safety by reducing the risk of short circuits under high voltage conditions.
Q: How does the 175U3310 resist the impact of humidity during operation?
A: It operates effectively within a 5-85% humidity range, without condensation. This range makes it well-suited for environments where fluctuating moisture levels are present, such as factories and outdoor applications.
