SENTROL-EM3

Description: Soft Start Controller.

Application: Reduced Voltage Starting of Three Phase A C Motors.

Features:

   PROTECTION:-----1) 2-millisecond Fuses are standard with every SENTROL-EM3.
                   2) Vbo Clamping, integral to the power circuit design, provides
                      Transient Voltage Surge Protection for the semiconductors.
                   3) Natural Convection Cooling of the integral heatsink chassis
                      allows a 50 degree-C Operating Temperature Rating at Full Load
                      without fans or thermal derating.
                   4) Standard Duty units use Class-10 Overload Relays, 
                      High Inrush units come standard with a Class-20 Overload Relay.
   SMART:----------1) Operates from any control input from 95-220VAC, or
                      to operate in line with existing across-the-line starter.
                   2) Adjustable Starting Torque.
                   3) Adjustable Acceleration Time.
                   4) Adjustable Deceleration Time.
                   5) LED Status indicators.
                   6) VISI-RAMP output indicator - optional)
 
  CONTROL OUTPUTS:-Seal Contact and End-of-Ramp Auxiliary Contacts standard on all units.
   COST EFFECTIVE:-Low unit cost, low installation cost, no regular maintenance required,
                   no mechanical parts to wear out or replace.

Note-1 KW ratings are calculated for: 230v starters at 230vac, for 460v starters at 380vac
Note-2 For 25hp, 208vac motors, use "High Inrush" starter only.
Note-3 For use on 380/415vac, must specify on order. Specify "-3-", use "-4-" prices,dimensions.
Note-4 For high inrush rating, add suffix "H" to model number. Example: for 460vac,100hp
       starter, with high inrush rating, the correct model number would be 18EM3-4-100HP3H.
