Slim Single-Phase Power Controllers with LED Display SPR1 Series

Product Overview

The SPR1 series single-phase power controllers are specifically designed for environments where space is at a premium, with a slim form factor that measures just 55 mm in width. These controllers feature an LED display that provides real-time monitoring of essential parameters, including control input, load voltage, current, power, resistance, and heat-sink temperature. The SPR1 series supports various control methods, such as phase control, cycle control, and ON/OFF control. Additionally, an advanced feedback control option (constant current, voltage, or power) is available, ensuring precise and stable power management.

Key Features

• Slim and Elegant Design: The SPR1 series is designed to fit into tight spaces without sacrificing performance.
• Real-Time Monitoring: The LED display offers live monitoring of crucial control parameters, ensuring optimal operation.
• Advanced Control Options: Includes phase control, cycle control, and ON/OFF control methods, with an optional feedback control for enhanced stability.
• Communication Capabilities: Models are available with RS485 communication output, utilizing the Modbus RTU protocol for seamless integration with existing systems.
• Comprehensive Alarm Functions: Features alarms for overcurrent, overvoltage, heater disconnection, fuse breakage, heat-sink overheating, and diode errors, providing robust safety and reliability.
• User-Friendly Installation and Maintenance: Designed for easy installation with mounting brackets and straightforward fuse replacement, minimizing downtime.
• High-Performance Components: Incorporates a high-performance SCR (Silicon-Controlled Rectifier) and IXYS diodes for efficient and reliable operation.

Communication Interface

The SPR1 series features an RS485 communication interface that supports Modbus RTU protocol. This allows for seamless integration into larger systems, with a maximum connection capacity of 31 units. The interface supports various communication speeds, ranging from 2,400 to 38,400 bps, and has a maximum communication distance of 800 meters. The communication setup includes asynchronous methods, with options for parity and stop bits.

Product Components

Each SPR1 controller comes with the following components: 

• The power controller unit.
• An 11-pin connector.
• An instruction manual for quick and easy setup.

Dimensions and Installation

The SPR1 series offers compact dimensions that vary depending on the rated load current:

• 25 A, 35 A, 50 A Models: Compact design with natural cooling.
• 70 A Model: Includes forced air cooling with a cooling fan.
• 100 A, 150 A Models: Larger units with additional cooling features to handle higher currents.

These dimensions are optimized for space-constrained environments, ensuring that the controllers can be easily integrated into existing systems.

Software Integration

The SPR1 series is compatible with Autonics' DAQMaster software, a comprehensive device management tool. This software allows for easy parameter setting, real-time monitoring, and efficient data management, enhancing the functionality and usability of the power controllers.
