Single phase — 2 HP Siemens V20 AC Drive
Siemens V20 AC drive, single-phase input, 2 HP / 1.5 kW.
Overview
This is a Siemens V20 variable frequency drive (model 6SL3210-5BB21-5UV0), rated 2 HP / 1.5 kW, taking a single-phase AC supply (200-240 V AC, 47-63 Hz) and outputting three-phase power to run a standard induction motor at variable speed. Rated input current is 19.7 A, output current 7.8 A - frame size B, cooled by a single fan.
It takes a 150% overload for 60 seconds, covers an output frequency range of 0 to 550 Hz, and offers linear, quadratic and multi-point V/f control plus flux current control (FCC), set up from its own built-in keypad with connection and application macros or over an RS-485 port running USS or Modbus RTU.
Double the power of the 1 HP model on the same single-phase input, useful where more current is needed but no three-phase supply is available. For more power, the 3 HP and 4 HP models step up further; where three-phase power is available, the three-phase-input V20 range (6SL3210-5BE series) starts at 4 HP and goes up to 10 HP.
The V20 is a genuine Siemens product, not a Tiny Controls design - it is supplied, not assembled or designed, in India.

Questions
What size motor or load does this suit?
Rated 2 HP / 1.5 kW output, 7.8 A output current — double the 1 HP model on the same single-phase supply, useful where more current is needed but no three-phase supply is available.
Can it really run a three-phase motor from a single-phase wall supply?
Yes. It takes single-phase 200-240 V AC in (47-63 Hz) and outputs three-phase power to run a standard induction motor at variable speed.
How is it programmed — keypad, or a PC?
Either: the built-in keypad (with connection and application macros), or remotely over an RS-485 port running USS or Modbus RTU.
What protects the drive if something goes wrong?
The standard SINAMICS V20 fault set: overcurrent (F1), overvoltage (F2), undervoltage (F3) and inverter overtemperature (F4) trips, per the manual's fault code table.
