Product Description:

As a product of Sanyo Denki, the PRS-1972B is represented as a servo amplifier. It belongs to the PRS Series, which focuses on controlling industrial automation. The amplifier provides capabilities for operating with single-phase or three-phase AC inputs. The amplifier functions at 200 to 240 VAC voltage. The control circuit needs power from a single-phase 200 to 240 VAC electrical supply.

The PRS-1972B servo amplifier features a 15 A capacity, which supports different operational requirements. The device uses IGBT-based sinusoidal PWM control system technology as its operation method. The PRS-1972B amplifier includes pre-installed regenerative resistors, which improve its energy efficiency. The device provides functionality for optical incremental encoders to achieve high measurement accuracy. The device uses 1000 or 2500 pulses per revolution as its encoder resolution options. The PRS-1972B servo amplifier contains built-in amplification together with encoder signal filtering functionality. The amplifier functions reliably between 0°C and +55°C. The storage temperature range supported by the device extends between -20°C and +65°C. The operation of this device works properly when the humidity levels exceed 90% RH to a point where condensation does not occur. The product operates effectively between 0 to 1000 meters elevation above sea level.

The PRS-1972B servo amplifier shows resistance to vibrations at levels of 4.9 m/s². This device confirms its ability to experience operational impacts at speeds reaching 19.6 m/s². Users can check for specific system status conditions through front-panel indicator lights present on the amplifier unit. Users can mount these amplifiers either on a DIN rail or custom brackets according to their needs. This unit structure is built to match the design of multi-axis control racks. The stainless steel build of this device enables it to endure tough industrial conditions.
