Product Description:
The VLT 8102 Frequency Converter is designed to provide a reliable efficient solution for controlling the speed and performance of motors. It is capable of controlling a wide range of motor types with varied voltage and frequency parameters. This device offers flexibility in operation with precise control over power delivery.
The VLT 8102 frequency converter operates within a wide voltage range and offers an output voltage of 0 – 100 % of the supply voltage. It also accommodates a frequency range from 0 to 120 Hz. The device supports a high true power factor of 0.90 at rated load and has a displacement factor near unity (greater than 0.98) that ensures efficient energy consumption. The frequency converter features an allowable on/off switching sequence of approximately 1 time per 2 minutes and a maximum short circuit current of 100 kA for strong protection against electrical faults. It is also equipped with eight programmable digital inputs that operate with a voltage level of 0 - 24 V DC with positive logic signals and an input resistance of around 2 kΩ. The scanning time per input is approximately 3 ms that ensures fast response times. The control card of this converter operates on a 24 V DC supply with a maximum load of 200 mA and a designated ground connection for added safety.
The VLT 8102 frequency converter from Danfoss delivers a starting torque of 110 % for one minute and can provide a high break away torque that reaches up to 130 % for 0.5 seconds. This ensures efficient motor start up even under load. The acceleration and overload torque are set at 100 % and 110 %, respectively.
Frequently Asked Questions about VLT 8102:
Q: What startup behavior can be expected from the MCD3018-T5-B21-CV4 when integrated into sensitive mechanical assemblies?
A: The unit uses a timed voltage ramp-up method to smoothly increase motor voltage to full line level. This reduces mechanical shock and electrical surges during initial engagement.
Q: How does the MCD3018-T5-B21-CV4 Soft Starter improve startup performance in high-friction motor applications?
A: It features an adjustable initial torque up to 85%, along with a kick start function for breakaway loads. This allows stable motor engagement even in high-inertia or tight mechanical systems.
Q: What control voltage flexibility does the MCD3018-T5-B21-CV4 offer for integration across diverse panel configurations?
A: It supports universal control voltage from 24 to 480 V AC or DC. This enables compatibility with varied control systems without requiring additional voltage adaptation hardware.
Q: How does the MCD3018-T5-B21-CV4 manage thermal stress during continuous duty operation?
A: Its heatsink is made of black anodized aluminum for effective thermal dissipation under extended load. Combined with a robust electroplated steel base, it maintains operational stability in warm enclosures.
Q: How suitable is the MCD3018-T5-B21-CV4 for systems requiring frequent cycling and rapid diagnostic feedback?
A: It allows unlimited start/stop cycles per hour on 15 A and 25 A models. The built-in LED status indicators provide immediate fault or operation status for faster troubleshooting.
