Product Description:
Kollmorgen developed the ROL-20012 as a high-performance analog amplifier that can provide precise control for tough tasks. The ROL amplifier works over a range of 2000:1 speeds and gives off a steady 12 ADC current, making sure that it works well and reliably. The amplifier works with industrial control systems that need to quickly and reliably change power sources. The ROL amplifier is very efficient in control applications thanks to its PWM switching frequency of 22 kHz ± 15%.
The amplifier is powered by the power line and can work with a main bus voltage range of 30 VAC to 130 VAC. The amplifier has a predictability of 0.2% full scale, which means that the output performance is always accurate. The highest frequency that can be used is 125 kHz that allows the signals to be processed quickly. The ROL-20012 Analog amplifier is made with a minimum inductance of 250 µH so it can work reliably in tough situations. The amplifier is very small, measuring 94 mm wide, 108 mm deep, and 187 mm tall. Its small size makes it easy to add to current systems. For continuous running at a temperature of 40°C, the amplifier sends out 12 ADC of current all the time.
The ROL-20012 analog amplifier uses a protected standard that makes sure the system always works efficiently. The amplifier generates a peak current of 25 ADC for up to two seconds that provides the necessary power at times of heavy demand. The input voltage needs to be between 135 VDC and 190 VDC so that it can work with a variety of power sources. For long-term use, the amplifier needs a separate fan to keep the temperature at the right level. The design and specs make it possible for precise motion control and effective power stabilization in automation settings.
Frequently Asked Questions about ROL-20012-0000:
Q: Why does the ROL-20012 require a separate fan?
A: The amplifier generates heat during continuous operation that requires cooling. A separately mounted fan ensures optimal thermal management for stable performance.
Q: Does the ROL-20012 support high-speed signal processing?
A: Yes, the amplifier operates with a maximum frequency of 125 kHz. This enables precise control in fast-response applications.
Q: Do the voltage ranges of ROL-20012 ensure compatibility?
A: Yes, the main bus operates between 30 VAC and 130 VAC. The input voltage range of 135-190 VDC supports various power sources.
Q: Why does the ROL-20012 have a 250 µH inductance?
A: The minimum inductance of 250 µH stabilizes current flow. This ensures smooth operation and reduces the risk of fluctuations.
Q: How does the ROL-20012 maintain output precision?
A: It features 0.2% full-scale linearity that minimizes deviation. This guarantees accuracy in power delivery and signal control.
