Product Description:
The 195N1100 refers to VLT2875PT4B20SBR1DBF00A00C0 drive unit. It is designed for 7.5 kW or 10 HP motor applications. The VLT 2800 Low Voltage Drives from Danfoss are reliable AC drives.
The 195N1100 drive uses a rated supply of 3 × 380-480 V. It generates 7.5 kW or 10 horsepower of motor power. The output frequency range is adjustable between 0 and 120 Hz. It can handle an overload of 150% for 60 seconds. The switching frequency is temperature-controlled, ranging from 4.5 to 14 kHz. It is protected by UL-certified Bussmann KTS-R fuses. Motor connections are U, V, and W on terminals 96–98. The ground terminal is positioned at 99 to ensure safety. Terminals 81-82 can accept brake resistor connections up to 850 VDC. Cooling is accomplished using forced air and an integrated fan system. A clearance of 100 mm is required above and below the unit. The design enables for side-by-side mounting and unrestricted installation orientation. The motor cable length is supported up to 75 m unshielded or 25 m shielded. It has customizable digital inputs on terminals. Terminal 53 provides an analog input with a voltage range of 0 to 10 VDC. Terminal 60 provides a current input of 0/4-20 mA. The relay outputs on terminals 01-03 are utilized for status and alarms. Terminal 46 provides a digital output to indicate status or frequency. Terminal 42 supports analog output for frequency or torque signals.
The 195N1100 drive is protected by a UL class 20 electronic thermal relay. Automatic Motor Tuning evaluates stator resistance without spinning. The torque modes are constant torque, variable torque, CT-start, and special motor mode. Load sharing is enabled on DC bus terminals 88-89. The operating temperature ranges from 0 to 40 °C without derating. With derating, it may work at temperatures as high as 55 °C. The humidity tolerance is 5–85% non-condensing. The altitude is supported up to 1000 m without derating. It offers stable performance for industrial and commercial motor control.
Frequently Asked Questions about 195N1100:
Q: How does the temperature-controlled switching frequency benefit the 195N1100 VLT Drive?
A: It reduces heat stress on internal components. This ensures longer lifespan and stable drive performance during varying load conditions.
Q: Why are shielded cables recommended for the VLT 2800 Low Voltage Drives?
A: Shielded cables help reduce electromagnetic interference during operation. This improves drive communication reliability and compliance with EMC standards.
Q: How does the 195N1100 VLT Drive handle high ambient temperatures?
A: It operates up to 40 °C without derating. With derating applied, it can still function reliably up to 55 °C.
Q: Why is an Electronic Thermal Relay used in the 195N1100 VLT Drive?
A: The relay provides precise motor thermal protection. This prevents overheating and extends motor service life under heavy operation.
Q: What advantage does the forced air cooling method provide?
A: Forced air cooling keeps components at safe operating temperatures. It also allows consistent performance even in compact installations.
