Aluminum Base Soft Starter for Single and 2-Phase Motor Control

Feature: 1. Motor Start Module supports soft start for water pumps, fans, vehicles, and standard single-phase motors. 2. Soft start controller can replace adjustable auto-transformers, inverter-based soft start systems, and similar devices. 3. Simple wiring design; no bypass contactor required, making it cost-effective, practical, and efficient. 4. Easy installation with no complex operations needed. 5. Designed for reliable performance, the motor start board delivers consistent operation over extended periods. Specification: Item Type: Motor Start Board Type: Module / Module + Radiator (optional) Model: SSR-20WA-R1 (1KW) (with soft start, without soft stop) Voltage Compatibility: Single-phase 220VAC, 2-phase 380VAC, Frequency: 50-60Hz Soft Start Time: Adjustable from 0 to 30 seconds (refers to voltage rise from 0 to 220V or 0 to 380V) Starting Voltage: Adjustable from 0% to 50% of rated voltage (220V–380V) Two Operation Modes: 1. When the switch is closed, main power is connected and soft start initiates automatically. 2. Use the switch to control operation: close to start (soft start initiates), open to stop. Adjustment Examples: - At half adjustment of starting potentiometer: starting voltage is approximately 200V. - Maximum soft start time is 30 seconds, reaching full output voltage (380V). Power Supply 220V: - Half adjustment: initial voltage 55V, soft start duration ~22 seconds - Full adjustment: voltage rises from 110V to 220V in approximately 15 seconds Power Supply 380V: - Half adjustment: initial voltage 95V, soft start duration ~22 seconds - Full adjustment: voltage rises from 190V to 380V in approximately 15 seconds Dimensions: Size 1: Approx. 92mm x 74mm x 47mm (3.6in x 2.9in x 1.9in) Approx. 104mm x 35mm x 43mm (4.1in x 1.4in x 1.7in) Size 2: Approx. 125mm x 80mm x 110mm (4.9in x 3.1in x 4.3in) Approx. 28mm x 100mm (1.1in x 3.9in) Package List: 1 x Module
