Single phase — 1 HP Siemens V20 AC Drive
Siemens V20 AC drive, single-phase input, 1 HP / 0.75 kW.
Overview
This is a Siemens V20 variable frequency drive (model 6SL3210-5BB17-5UV1), rated 1 HP / 0.75 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 - a spindle motor, for instance - at variable speed. Rated input current is 10 A, output current 3.9 A - frame size A, air-cooled without a 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.
At 0.75 kW this is the smallest drive in the range, suited to a light spindle rather than a heavier load. For more power on the same single-phase supply, the 2 HP, 3 HP and 4 HP models step up; where a three-phase supply is available, the three-phase-input V20 range (6SL3210-5BE series) starts at 4 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 1 HP / 0.75 kW output, 3.9 A output current — the smallest model in this single-phase range, suited to a light spindle rather than a heavy load.
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.
What's the overload capacity?
150% overload for 60 seconds.
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 if I need more power, or have a three-phase supply available?
On the same single-phase supply, the 2 HP, 3 HP and 4 HP models in this range step up. Where a three-phase supply is available instead, the three-phase-input V20 range (6SL3210-5BE series) starts at 4 HP.
