Simple installation of such a motor controller does not require particularly complicated operations. 3. No need to connect bypass contactor, economical and practical, such a motor controller is powerful. 4. Thanks to the craftsmanship of many experts, such engine starting board is entitled to high performance according to strict rules. 5. The motor start module supports the possibility of replacing adjustable autotransformer, inverter soft start, etc. Specifications: Item Type: Motor Start Board Type: Module/Module + Heatsink (Optional) Model: SSR-60WA-R1 (2KW) (with soft start without soft stop) Voltage compatibility: single-phase 220VAC, two-phase 380VAC, frequency: 50-60Hz Soft start time: adjustable from 0 to 30 seconds (soft start time refers to the whole process from 0 to 220 V, 0 to 380 V) Start voltage Adjustable from 0 to 50 % to rated voltage (220- 380V) Two ways to use: 1. When the switch is closed, the main power is turned on and soft start begins. 2. Use the switch to control, first close the soft start, open the shutdown When the start potentiometer is set to half, the start is 200V, the maximum time of the soft start potentiometer is 30 seconds , which corresponds to the full range of 380V. For example: when fully adjusted to the minimum: initial voltage 0V soft start 0 seconds (0 seconds is not recommended) 220V power supply: when fully adjusted to half, the initial 55V, the soft start time is about 22 seconds 380V power supply: When fully adjusted to half, the initial 95V, the soft start time is about 22 seconds 220V power supply: when fully adjusted to the maximum, the initial voltage from 110V to 220V takes 15 seconds 380V power supply: When fully adjusted to the maximum, the initial voltage from 190V to 380V takes 15 seconds Size1: Approx. 92mm / 3.6inch Approx. 74mm / 2.9inch Approx. 47mm / 1.9inch Approx. 104mm / 4.1inch Approx. 35mm / 1.4inch Approx. 43mm / 1.7inch Size 2: Approx. 125mm / 4.9inch Approx. 80mm / 3.1inch Approx. 110mm / 4.3inch Approx. 28mm / 1.1inch Approx. 100mm / 3.9in Package List: 1 x Module
