RVS-N

Analogue Soft StarterRVS-N

Heavy Duty Analogue Starter,

for Motors 4-90KW, 220-690V

For small to medium size motors, in demanding applications, the

RVS-N provides an optimal solution. Ease of installation and operation

and incorporating Current Limit and Motor Protection,makes the

RVS-N an ideal cost effective replacement for Star-Delta and Auto-

Transformer starters.

 

Advantages at a glance

  • * Reduced inrush current & mechanical shock
  • * Soft, smooth, stepless acceleration and deceleration
  • * Incorporating motor protection
  • * Maintenance free, all solid state
  • * Compact, light weight
  • * Easily installed and operated.
  • * Heavy duty design indicated by conservative SCR selection and heatsink and cooling systems designed for starting at 400% In for 30 sec. at 50oC ambient temperature, ensure reliable operation under harsh environmental conditions.
  • * Superior construction - IP20 up to 72A. Enclosed front panel for increased safety at higher ratings. Preparation for by-pass contactor standard above 72A.

 

Start Stop Parameters

  • Motor Full Load Current (FLC)
  • This adjustment allows easy matching of the RVS-N to the motor and application. All current based functions (overload, electronic fuse, current limit) are associated with this setting. Range 45-100% of RVS-N rated current.

 

Motor & Starter Protection

  • * Electronic Overload - Inverse time Electronic Overload. Operational at end of acceleration process or after a time delay as set on the Overload Delay.
  • Adjustable 75-150% of starter FLC
  • * Phase Loss - Operational when starter is energized and protects 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 to above 85oC.
  • * Fault logic, Trip and Reset circuits. When any protection operates, the starter locks in fault mode, disabling thyristor firing, the LED indicates the fault, the fault relay trips, and the Trip contact closes.

 

Typical applications

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

Known betweeen 1997-2002 in and around Germany as ESA 3000. Manufactured for a Fanal Germany, the product successor is the RVS-AX. <<< Click this Link
