This Thomson TS 880 Automatic Transfer Switch is ideal for mission critical commercial and industrial three phase applications up to 1200A. Open Transition configuration is standard. Options include Closed Transition and Bypass Isolation.

TRANSFER SWITCH FEATURES

  • Numerous three phase voltages available up to 600V – 3-wire or 4-wire systems. Three or four poles.

  • Two user Programmable Output Contacts rated 2A, 24VDC resistive and Two user Programmable Output Contacts rated 15A, 24VDC resistive, Form A. Each
    output contact is user programmable to 20 different functions including: Load on Utility, Load on Gen, Load Disconnect Contact (LDC), Fail to Transfer (FTT), Utility Power Available (UPA), Generator Power Available (GPA), Utility Power Fail, ATS Not in Auto, and ATS in Auto.
  • The Transfer Switch is pre-programmed with the following outputs enabled: Load on Utility, Load on Gen, Load Disconnect Contact (LDC), Fail to Transfer (FTT), and ATS Not in Auto.
  • Local and remote utility power fail simulation test.
  • Local plant exercise initiate push-button control.
  • Engine start contact (8A, 120/240VAC resistive max.).
  • Transfer fail/forced transfer logic.
  • Automatic force transfer to alternate supply should load voltage become de-energized.
  • 24VDC control power.
  • Remote Load Test/Peak Shave Input.
  • Under/Over Frequency Protection- Utility and Generator Sources.
  • 3 Phase Over Voltage Protection – Utility and Generator Sources.
  • Phase Sequence and Phase Rotation Protection between Utility and Generator Sources.
  • Voltage Phase Loss/Unbalance Protection.
  • Programmable Inputs (Quantity 8 Digital Input-voltage free input).
  • RS485 Modbus Remote Communication Port (Modbus Serial RTU).

CLOSED TRANSITION OPTION

  • Employs two electrically interlocked insulated case power switching units and a microprocessor based controller to automatically allow a Closed Transition load transfer when both utility and generator sources are available.
  • All Closed Transition transfer sequences ensure both sources of power are in synchronism prior to transfer and load is transferred without power interruption.
  • Automatic control & protection circuits ensure the generator and utility supplies are only in parallel for a maximum of 100 milliseconds to permit an uninterrupted load transfer.
  • Reverts to an Open Transition load transfer sequence when only one power source is available.
  • Ideal for Emergency Power System applications such as commercial, industrial, or government institutions that require automatic standby power and minimal power interruptions to the load.
  • Allows optional use of integral over current trip elements within the power switching units thus eliminating the need for external, upstream protective devices.

BYPASS ISOLATION OPTION

  • Employs an interlocked power switching mechanism that provides an easy and safe procedure for system maintenance personnel to manually isolate and bypass the automatic transfer switch.
  • Manually operated switch allows either generator or utility source to be bypassed to maintain power to the load while the automatic transfer switch is tested for maintenance procedures as required.
  • Allows a fast, simple and reliable method of isolating and bypassing the automatic transfer switch through a “break-before-make” bypass design.
  • Mechanical interlocking mechanism ensures that the utility and generator sources cannot be paralleled under any circumstance and the transfer switch may be bypassed to either source.
  • Closed Transition option may be operated in a “make-before-break” sequence at the operators’ direction.
  • Supplied as a single complete assembly with all power conductors provided between the bypass mechanism and the transfer switch.
  • Provisions for all external power cabling for the utility, generator and load conductors are provided for in the bypass/isolation compartment of the switch.
  • Bypass/isolation switch and transfer switch are mounted in separate barriered compartments.
  • Bypass isolation mechanism consists of 2 mechanically interlocked power switch devices and draw-out transfer power switching devices with key interlock mechanism.
  • Utilizing independent switching units provides a high degree of reliability and redundancy not available in other switches.
  • Specifically designed and certified to UL 1008 and CSA 22.2 No. 178 Safety Standards.
