Low Voltage Soft Starters: RVS-AX

RVS-AX

Ratings: 8-170A, 230-600V
The RVS-AX provides an optimal solution for small to medium size motors, with the simplicity of
analog control. Easy to install and operate, but with built in Current Limit and Motor Protection, the
RVS-AX
is an ideal cost effective replacement for Star-Delta and Auto-Transformer type starters.

RVS-AX Information

The analog soft starter with a built-in bypass

RVS-DXM Combo

For small to medium size motors the RVS-AX provides an optimal solution. The RVS-AX includes Current Limit and Motor Protection and is a cost effective replacement for Wye-Delta and Auto-Transformer starters.

RVS-AX Application

Advantages at a Glance

  • Reduced inrush current & mechanical shock
  • Soft, smooth, stepless acceleration and deceleration
  • Built-in motor protection
  • Maintenance free, all solid state, with a built-in bypass (31-170A)
  • Compact, small footprint, book type, light weight - all aluminum case
  • Easily installed and operated
  • Heatsink and bypass system designed for starting at 350% In for 20 sec. at 40°C ambient temperature
  • Superior construction - IP20 up to 58A. Enclosed front panel for increased safety

Motor and Starter Protection

  • Electronic Overload - Inverse time Electronic Overload. Operational at end of acceleration process
  • Phase Loss - Operational when starter is energized and protects the motor from single phasing. Trips the starter when one or two phases are missing for more than 1 sec.
  • Heatsink Over Temperature Protection - A thermal sensor mounted on the heatsink trips the starter when the temperature rises.
  • Fault logic, Trip and Reset circuits. When a protection operates, the starter locks in fault mode, disabling SCR firing, the LED indicates the fault, and the Trip contact closes

LED Indicators

  • On - line voltage connected
  • Ramp Up / Down
  • Run
  • Overload
  • Phase Loss
  • Over Temperature

Auxiliary Relays

  • End of Acceleration Relay, one-N.O contact
  • Fault Relay, one-N.O contact

Typical applications

  • Pumps
  • Fans
  • Compressors
  • Conveyors and monorail systems
  • Weak power source starting (diesel generators, long cables, etc).
