220V 1KW-8KW Adjustable Single Phase Motor Soft Starter Module Industrial Use

The start potentiometer sets the initial voltage to 200V when adjusted halfway.The soft start potentiometer provides a maximum ramp-up time of 30 seconds, corresponding to a full output of 380V.Example settings:- Minimum adjustment: starting voltage 0V, soft start duration 0 seconds (not recommended)- Power supply 220V, set to halfway: start voltage 55V, soft start time approximately 22 seconds- Power supply 380V, set to halfway: start voltage 95V, soft start time approximately 22 seconds- Power supply 220V, set to maximum: start voltage 110V to 220V, soft start time approximately 15 seconds- Power supply 380V, set to maximum: start voltage 190V to 380V, soft start time 15 secondsRecommended model selection margin: SSR-60WA-R for 2.2kW applications.This product is suitable for motors operating at the following voltages:- 220V (50Hz, 60Hz)- 230V (50Hz, 60Hz)- 240V (50Hz, 60Hz)These voltage ranges are compatible with this device.Applications for single-phase 220V soft start modules include:Petroleum, chemical, fire protection, construction, metallurgy, building materials, mining, environmental protection, and related industries.Suitable for fans, pumps, belt conveyors, ball mills, car wash machines, conveyors, and compressors.Ideal replacement for traditional reduced-voltage starting methods such as star/delta starters, autotransformer starters, magnetic starters, and inverters.Single-phase motor soft start module (motor control application):Models available:- SSR-20WA-R1 (1kW)- SSR-40WA-R1 (1.5kW)- SSR-60WA-R1 (2kW)- SSR-100WA-R1 (4kW)- SSR-150WA-R1 (6kW)- SSR-200WA-R1 (8kW)Selection guideline: Calculate based on 5 times the actual operating current: Power ÷ Voltage × 5Example: For an 8000W motor at 220V: 8000 ÷ 220 × 5 = 181.81A → select 200WA model (closest match).This soft start module is compatible with various single-phase motors, regardless of capacitor use.For continuous operation, motors above 2000W require an external heat sink.Voltage compatibility:- 220V + 0V = single-phase 220V AC- 230V + 0V = single-phase 230V AC- 240V + 0V = single-phase 240V AC- 220V + 220V = two-phase 380V–400V ACFrequency range: 50Hz, 60HzSoft start time is adjustable from 0 to 30 seconds (refers to the complete voltage rise from 0 to 220V or 0 to 380V).Gradually increases output voltage from 0V to full rated voltage (220V or 380V).Two operational modes:1. Close the switch to energize the main power and initiate soft start.2. Use the switch to control start and stop functions—close to start, open to stop.Available configurations:- SSR-40WA-R1: Soft start function only- SSR-40WA-R2: Includes both soft start and soft stop functionsNotes:- Do not apply voltage directly to the control switch.- Do not use a multimeter on the load side to assess product functionality.- Performance subject to field testing.Operating temperature range: -25°C to 60°C
