Siemens SINAMICS V20 6SL3210-5BB13-7UV1 0.37 kW 1-Phase VFD

Siemens SINAMICS V20 6SL3210-5BB13-7UV1 0.37 kW 1-Phase VFD

The 6SL3210-5BB13-7UV1 is a Siemens SINAMICS V20 compact variable-frequency drive for controlling an appropriately selected three-phase AC motor from a single-phase AC supply. It is the 0.37 kW, 200–240 V, unfiltered FSAA product version. A built-in Basic Operator Panel and built-in USS / Modbus RTU communications support local and serial configuration; IP20 construction means appropriate protection and cabinet design may be necessary. The converter is intended for variable-speed applications where the motor rating and drive duty are correctly matched.

Electrical Ratings

This 0.37 kW SINAMICS V20 converter receives single-phase AC power and delivers adjustable-frequency, three-phase motor output. The Siemens datasheet gives a 200–240 V AC nominal input with −15%/+10% tolerance and 47–63 Hz line frequency. Output voltage is listed as 230 V IEC or 240 V NEC nominal, subject to the available input voltage and drive operating conditions. The drive is not a voltage step-up device.

Both Low Overload (LO) and High Overload (HO) power are 0.37 kW, and both continuously rated currents are 2.30 A. The Siemens datasheet lists 0.37 hp for LO and 0.50 hp for HO; these are manufacturer-listed classifications, not conversions. Siemens notes the output-current and HP ratings apply at 220–240 V. The programmable output frequency range is 0–550 Hz; the motor and machine manufacturer must determine the safe operating speed.

Control Modes and Performance

The SINAMICS V20 family provides voltage/frequency (V/f) control for general-purpose variable-speed motor operation; commissioning and supported V/f characteristics must follow the drive operating instructions. For this exact power variant, Siemens specifies LO overload of 110% rated output current for 60 seconds on a 300-second cycle. The HO overload rating is 150% for 60 seconds on a 300-second cycle. These percentages describe temporary current capability, not continuous motor-current ratings. Match starting and operating loads to the correct duty class and apply applicable derating.

Communication and Configuration

The model includes USS and Modbus RTU communication. These are serial protocols, distinct from Ethernet communications; configuration details and wiring are governed by the Siemens operating instructions. The converter has a built-in Basic Operator Panel (BOP) for local setup and parameter access. Siemens product information identifies four digital inputs, two digital outputs, two analog inputs and one analog output for the variant. Verify wiring and signal functions before connection. Optional interface accessories must not be assumed to be supplied.

Braking, EMC and Built-in Functions

Part number 6SL3210-5BB13-7UV1 is the unfiltered version: Siemens specifies no integrated EMC line filter. It must not be described as having the integrated Class C1 filter of 6SL3210-5BB13-7BV1. The exact product datasheet identifies no integrated braking chopper. Do not assume a braking resistor, braking unit or dynamic-braking module is included. Any external EMC measures, line filters, cable shielding, grounding or braking accessories must be chosen for the installation and compliant drive configuration. V20 functionality includes parameterized speed control and application functions documented for the family, but no certified safety function or onboard PLC is asserted here.

Installation and Typical Applications

The FSAA enclosure is rated IP20 / UL open type and uses convection cooling. Manufacturer dimensions are 68.0 × 142.0 × 107.8 mm (W × H × D). Wall or side-by-side mounting is specified. Siemens lists an installation altitude of 1,000 m before altitude-dependent considerations and an operating ambient range of −10 to 60 °C; output derating is required at temperatures of 40 °C and above. Maximum listed motor cable lengths are 25 m shielded and 50 m unshielded, subject to installation and EMC requirements.

Potential uses include speed control for appropriately rated small fans, pumps, conveyors, agitators and simple machinery. These are technically suitable examples rather than guarantees of compatibility. Confirm motor current, load torque, starting duty, heat dissipation, wiring, stop behavior, and applicable machine protections before selection.

Exact Variant Verification

The exact Siemens number 6SL3210-5BB13-7UV1 identifies the 0.37 kW, single-phase 200–240 V AC, unfiltered FSAA unit. The similar 6SL3210-5BB13-7BV1 is a filtered Class C1 variant and must not be substituted without checking the electromagnetic-compatibility design. Likewise, the older UV0 designation has a different mechanical frame and supply tolerance; its specifications must not be copied to UV1. The Siemens manufacturer documentation used here establishes the electrical identity; motor-specific installation decisions require the actual application information.
