CONDITION : BRAND NEW PRODUCT WITH ALL ITS ACCESSORIES AND SOFTWARE DISK INSIDE ITS ORIGINAL BOX

Key Features & Specifications

1. Model & Revision

   • Part Number: 8440-1868

   • Revision: K (latest firmware/hardware updates)

   • Series: DTSC 200 (Digital Transfer Switch Controller)

2. Primary Functions

   • Automatic Transfers: Switches between power sources (e.g., Utility ↔ Generator) upon failure.

   • Closed Transition: Supports in-phase transfers (load uninterrupted) where configured.

   • Engine Start/Stop: Integrates with generator control systems.

   • Load Shedding: Prioritizes critical loads during low-power conditions.

3. Inputs & Outputs

   • Voltage Sensing: 120–600V AC (phase-to-phase or phase-to-neutral).

   • Frequency Monitoring: 40–70 Hz (adjustable thresholds).

   • Relay Outputs: 6–12 configurable contacts (for breaker control, alarms).

   • Communication: RS-485 (Modbus RTU) or optional Ethernet/IP for SCADA.

4. Settings & Programmability

   • Adjustable Timers:

     • Transfer delay (0–30 sec).

     • Retransfer delay (0–60 min).

     • Cool-down delay (engine cooldown post-transfer).

   • LED Indicators: Status for power sources, alarms, and active relays.

5. Environmental & Certifications

   • Operating Temp: -40°C to +70°C (-40°F to +158°F).

   • Standards: UL 1008 (ATS compliance), IEC 60947-6-1.

Typical Applications

• Data Centers: Uninterrupted power during outages.

• Hospitals: Critical load transfers to backup generators.

• Industrial Plants: Process continuity with redundant power.

• Wiring & Installation

  1. Voltage Inputs:

     • Connect to Source 1 (Utility) and Source 2 (Generator) via potential transformers (PTs).

  2. Control Outputs:

     • Wire to ATS motor operator or breaker coils.

  3. Communication:

     • RS-485 for Modbus integration with BMS/SCADA.

  Configuration Steps

  1. Set Voltage/Frequency Thresholds: Define under/over-voltage and frequency limits.

  2. Adjust Timers: Customize transfer/retransfer delays per application.

  3. Test Mode: Simulate power failures to verify ATS response.
