Siemens SINAMICS V20 7.5 kW 3-Phase VFD 6SL3210-5BE27-5UV0

6SL3210-5BE27-5UV0 is the Siemens SINAMICS V20 basic converter rated for a 7.5 kW motor on a three-phase 380–480 V AC supply. This specific UV0 configuration has no integrated EMC filter. Siemens’ exact-part technical datasheet explicitly confirms an integrated braking chopper, so it must not be confused with lower-power UV0 devices that may have different braking hardware. Designed for general-purpose speed control of compatible AC motors, it combines adjustable output frequency, local operator controls and serial communication in an IP20 drive.

Electrical Ratings

The three-phase input supply rating is 380–480 V AC with a stated tolerance of −15%/+10%, at 47–63 Hz. The output is three-phase, with a nominal rating of 400 V under IEC conventions and 480 V under NEC conventions. Siemens specifies 7.50 kW for both Low Overload and High Overload settings, and lists 10.00 HP for the applicable 440–480 V rating range. Continuous rated output current is 16.50 A for both modes. Siemens’ older operating instructions identify a rated input current of 20.7 A. Output frequency is adjustable from 0 to 550 Hz; this is the converter capability, not a guarantee that every connected motor or machine can operate at that speed.

Control Modes and Overload Performance

The SINAMICS V20 family supports fundamental adjustable-frequency motor operation with drive parameterization and ramp control. The exact-part datasheet separates Low Overload (LO), which permits 110% of rated output current for 60 seconds per 300-second cycle, from High Overload (HO), which permits 150% for 60 seconds per 300-second cycle. Both modes list a nominal 16.50 A output current for this exact part. Application selection must consider transient torque, mechanical load, starting conditions, ambient temperature and any required derating.

Communication and Configuration

Siemens specifies USS and Modbus RTU communication for this inverter. These are serial drive protocols and should not be described as Ethernet communication. The official product listing confirms a built-in Basic Operator Panel (BOP) for local configuration and operation. The manufacturer lists four digital inputs, two digital outputs, two analog inputs and one analog output; the detailed electrical characteristics of each terminal must be checked in the installation instructions before wiring. Optional supervisory interfaces, controllers and gateway hardware are separate system components, not confirmed accessories included with this part.

Braking, EMC and Built-in Functions

The integrated EMC-filter class is expressly ‘Unfiltered’. Where EMC compliance or conducted-emission limits require filtering, external filtering and proper cable routing, grounding and installation practices must be engineered for the installation. Importantly, Siemens’ exact-part datasheet identifies an integrated braking chopper (‘Yes’). This built-in switching hardware is not the same as a braking resistor: an appropriately rated external resistor may be required for dynamic braking, and its compatibility and thermal protection must be determined from official Siemens instructions. Do not assume a resistor is supplied with the inverter.

Installation and Protection

The enclosure is IP20 / UL open type and requires a suitable electrical cabinet or other protective installation appropriate to the environment. Siemens assigns frame size FSD with physical dimensions 240.0 × 206.5 × 172.5 mm (width × height × depth). The documented cooling method uses an external fan. Datasheet ambient-operation information spans −10 to +60 °C, with derating precautions at 40 °C or above; installation altitude is stated as 1,000 m before additional derating considerations. Observe the manufacturer mounting clearances, permissible cable lengths, shielding recommendations and electrical safety practices.

Typical Industrial Uses

This drive may be suitable for pumps, fans, ventilation equipment, conveyors, mixers and other general-purpose variable-speed machines where the motor electrical characteristics and duty are compatible with its ratings. Such examples are application suggestions, not confirmation of compatibility with every motor, mechanical load or control architecture. Select the actual motor and driven machine using rated current, torque demand, acceleration and braking needs, ambient conditions and the applicable electrical protection requirements. The available integrated chopper can support a separately engineered dynamic-braking arrangement where necessary.

Exact Variant and Source Verification

This product is the unfiltered 7.5 kW UV0 variant, part number 6SL3210-5BE27-5UV0. The similarly rated CV0 configuration has integrated EMC filtering, while newer UV1 and CV1 ordering numbers may have different enclosure sizes and other characteristics. Siemens’ official exact-part PDF is the authority for the stated FSD dimensions and confirmed integrated braking chopper; do not transfer ratings or size from a successor drive. The Siemens product portal currently labels this part as ‘Phase Out Announce’.
