1 IntegraPower Features and Models

2 L1L2L3 T1T2T3 RS-232 cable to PC TB1 connections: Remote ON/OFF Remote indicator light Y-  Control Bypass contactor control TB2 connections: Remote power supply Escalator safety chain Indicator LEDs Line Side Load Side (to motor) Basic Connections 35A IntegraPower-E

3 Operator Interface Software MAIN CONTROL SAVINGS CONTROL SOFT START SAFETY CONTROL SOFT STOP WYE-DELTA CONTROL DATA FEEDBACK

4 Two Energy Saving Methods Combined in One Controller 1. Power Attenuation using SCRs 2. Intelligent Y-  Switching

5 Energy-Saving Method 1: Power Attenuation Using SCR Switches

6 Motor A AA a bc V VV Voltage Sensors Current Sensors SCR Switches Voltage Zero Crossing Current Zero Crossing A / D Calculate Phase Angle SCR Control Signal Digital Signal Processor Basic Architecture 3-Phase Power Phase angle between current & voltage Light Motor Load: large phase angle Heavy Motor Load: small phase angle

7 Energy Saving Method Explained Further… No SavingsWith Savings Voltage AC Waveform Current AC Waveform

8 kW without IntegraPower controller 2.05 kW with IntegraPower controller1.43 kW reduction29.5% Escalator Example: Nevada Casino (up escalator)

9 Energy-Saving Method 2: Intelligent Wye/Delta Switching (if Y-  starter present)

14 Y- and Voltage Reduction Savings

15 Example Wiring Diagrams

16 Basic Connection

17 With 2 button On/Off Control

18

19 PLC Remote Control

20 Indicator Light Control GREEN – Control board has power Self test passed YELLOW – Start signal received (controller will output power to motor) AMBER – Controller is in savings mode (Y – Delta) RED – Fault condition detected Switch S1 - setting selects when 1 to 2 shorts

21 Like most Soft Starters

22 Bypass & Disconnect

23 WYE – Delta

24 The Logic for Y - Delta

25 Escalator

26 Typical Industrial Application

27 Mounting on Unistrut

28 Power Quality Capacitors  Data taken on GE 4 pole motor for 2 different loads (PF =.87 and PF =.64 before the capacitors.  Based upon this limited data, it is observed that the % KW savings is slightly higher with the capacitors than without the capacitors. The % KVA savings is slightly lower with the capacitors than without the capacitors.
