Three phase — 10 HP Siemens V20 AC Drive
Siemens V20 AC drive, three-phase input, 10 HP / 7.5 kW.
Overview
This is a Siemens V20 variable frequency drive (model 6SL3210-5BE27-5UV0), rated 10 HP / 7.5 kW, taking a three-phase AC supply (380-480 V AC, 47-63 Hz) and outputting three-phase power to run a standard induction motor at variable speed. Rated input current is 20.7 A, output current 16.5 A - frame size D, cooled by two fans.
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.
This is the largest and highest-power drive in this catalogue's V20 range, sized for a heavily loaded spindle or motor drawing toward 7.5 kW. For less power on the same three-phase supply, the 4 HP, 5 HP and 7 HP models step down; there is no single-phase-input option anywhere near this rating.
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 10 HP / 7.5 kW output, 16.5 A output current — the largest and highest-power drive in this catalogue's V20 range, sized for a heavily loaded spindle or motor drawing toward 7.5 kW.
Does it need a fan, or is it convection-cooled?
Fan-cooled — frame size D, cooled by two fans (the only model in this range with two).
What input supply does it need?
Three-phase 380-480 V AC, 47-63 Hz.
Does it include a braking resistor?
No. On this frame size (D), the braking resistor's continuous power and duty cycle are set via parameter P1237 rather than the dynamic braking module used on frame sizes A-C — but it's still an external, separately-fitted resistor, not built in. The drive's own DC-link overvoltage trip (fault F2) protects it if one isn't fitted, but a sustained regenerative load needs the resistor to avoid tripping.
What if I need less power, or only have a single-phase supply?
For less power on the same three-phase supply, the 4 HP, 5 HP and 7 HP models step down; there is no single-phase-input option anywhere near this rating.
