SR3000 2SR40700 Snubber Resistor Braking Kits for 230 V and 460 V GV3000/SE Drives

The SR3000 Snubber Resistor Braking Unit connects to 230 V GV3000/SE drives of 15 HP or larger and 460 V GV3000/SE drives. It is used to dissipate the power regenerated by the motor during rapid deceleration or during overhauling load conditions.
The regenerated energy is normally consumed, as shownin figure 1, by mechanical loss, by the motor, and by the drive. The remaining energy is stored in the drive’s DC bus capacitor. If the remaining energy causes the capacitor voltage to rise above the normal operating range, the Braking Unit will discharge the regenerated energy before the drive voltage becomes excessive. Two units can be connected (paralleled) o provide increased wait dissipation.

Product Description

The SR3000 Snubber Resistor Braking Unit connects to 230 V GV3000/SE drives of 15 HP or larger and 460 V GV3000/SE drives. It is used to dissipate the power regenerated by the motor during rapid deceleration or during overhauling load conditions.
The regenerated energy is normally consumed, as shownin figure 1, by mechanical loss, by the motor, and by the drive. The remaining energy is stored in the drive’s DC bus capacitor. If the remaining energy causes the capacitor voltage to rise above the normal operating range, the Braking Unit will discharge the regenerated energy before the drive voltage becomes excessive. Two units can be connected (paralleled) o provide increased wait dissipation.

Overload protection of the snubberresistor is provided via the terminalstrip I/O on the faceplate for connection to a user-supplied protection circuit and by the status LEDs. If an overload fault occurs, the Braking Unit will shut down. Figure 2 showsthe faceplate of the Braking Unit with the terminal strip cover removed. Refer to table 1 for a description of the LEDs.

Product parameter

Installing the Braking Unit consists of the following steps:
Mounting the Braking Unit
e Selecting an external resistor, if required
e Installing an external resistor, if required
e Setting the snubberresistor overload detection level
e Wiring the Braking Unit
e Mounting the Braking Unit
e Refer to the dimensionsin figure 3 and use the following guidelines when mounting the Braking Unit:
e Leave a minimum of 50 mm (2 in} clearance between the Braking Unit and the drive.
e Leave a minimum of 80 mm (3.1 in) clearance above and below the Braking Unit.
e if two Braking Units are installed in parallel, leave a minimum of 50 mm (2 in) clearance between each unit.
e Do notinstall the Braking Unit under the drive.
e Grounding the Braking Unit
Usethe following steps to ground the Braking Unit:
e Remove the front cover from the front panel.
e Runa suitable equipment grounding conductor unbroken from the Braking Unit ground terminal to the
earth ground. See figure 2 for the location of the Braking Unit ground terminal.
e Re-attach the front cover.

Application field

SR3000 has a wide range of applications, which can be summarized in the following main aspects:

Electrical Test and Measurement:
The SR3000 four-probe test system is widely used in surface resistance and resistivity testing of ordinary rectangular samples such as liquid crystal display (LCD), ITO, glass, film, etc. This system has the characteristics of remote work and automatic assembly, which meets the needs of automated testing.
Speech recognition and Processing:
The ISD-SR3000 is a new embedded speech recognition processor from Winbond. It integrates a speech recognition engine, a speech compression engine, and recording capabilities to recognize continuous speech signals and support user-defined speech tags. This processor has a low current consumption (only 12mA) in low power mode and is widely used in storable instrumentation, automation control systems, wireless phones, home networks, Internet equipment and other systems.
Water supply control:
The SR3000 variable frequency constant pressure water supply controller is a flow controller used in automated water supply systems. By adjusting the speed of the pump, constant pressure water supply is achieved to ensure the stability and reliability of the water supply system.
Network communication:
Moxa SR3000 Internet Router is a network connection solution for small and medium-sized enterprises, which uses efficient and stable T1/E1 lines, ISDN or asynchronous dial-up to realize enterprise information sharing, remote network access and external Internet networking.
Industrial Automation and Monitoring:
The SR3000 product series is widely used in industrial automation and monitoring systems, such as power, petroleum, chemical, metallurgy, water treatment and other industries, due to its high automation, high reliability, network communication and other functions.
Data acquisition and processing:
Through the operation of dedicated software and personal computers, SR3000 series products can perform a variety of data analysis to meet the needs of data acquisition and processing.
In summary, SR3000 series products are widely used in many fields such as electrical testing, speech recognition, water supply control, network communication, industrial automation and monitoring, and data acquisition and processing.
