SSD61: The Uninterrupted Guardian for Your Most Critical Motors.
 
The SSD61 Series is Janson Controls’ premier online (full-time) soft starter, specifically engineered for mission-critical applications that demand zero-gap protection. While standard starters bypass after startup, the SSD61 remains fully active in the circuit, providing real-time diagnostic intelligence and an unbreakable safety shield for your motor 24/7.

Always-On Surveillance: By staying online during the entire run cycle, the SSD61 continuously monitors current, voltage, and thermal data, reacting instantly to any anomaly to prevent catastrophic motor failure.

Heavy-Duty Powerhouse: Capable of handling motors up to 110kW (230A), it is the preferred choice for massive industrial loads like primary crushers, heavy-duty mixers, and large-scale mining equipment.

Global Accessibility: Features a detachable, multi-language LCD (English, Russian, Chinese), allowing engineers worldwide to manage parameters and view fault histories in their native language.

Smart Engineering: Not just a starter, but a smart manager. With integrated logic for pumps and sensors, it simplifies complex system automation while ensuring peak operational reliability.

1.Continuous Full-Lifecycle Protection

  • Active Monitoring Mode: Stays in-circuit throughout the motor's operation. It captures even the smallest fluctuations in current or phase, providing a level of safety that bypass-style starters cannot match.

  • Comprehensive Safety Suite: 10+ built-in protections including Phase Reversal, Under-load (Dry-run), Motor Overtemperature, and Short Circuit.

2.Tailored for Heavy-Duty Industry

  • Optimized Start Curves: Selectable Voltage Ramp or Current Limit modes to handle high-inertia loads like Crushers, Ball Mills, and Large Centrifugal Fans.

  • Integrated Pump Logic: Ready-to-use software for water systems, supporting float switches and pressure gauge inputs directly into the starter.

3.Global Interface & Flexible Control

  • Detachable Multi-Lingual LCD: Allows for mounting on the cabinet door for safe monitoring. Supports English and Russian for global project deployments.

  • Rich System I/O: 3 programmable relays, 4-20mA analog output, and multiple digital I/O ports for seamless interlocking with PLC and SCADA systems.

4.Industrial-Strength Build

  • High-Capacity Design: Rated up to 230A with forced air cooling, ensuring stable performance in high-heat environments.

  • IoT & Remote Management: Built-in RS485 (Modbus-RTU) enables remote parameter tuning, fault diagnosis, and centralized data logging.
