Soft Start/Boot Module of Low-power Single-phase Motor
Simple Operation; 1-8KW
This module is compatible with 220V and 380V live lines, frequency 50-60HZ, soft boot is 30 seconds, adjustable (time rise: 0-220V). When the main power supply is 220V, the starting voltage starts from 0-110V to the rated voltage 220V; when the main power supply is 380V, the starting voltage starts from 0-180V to the rated voltage 380V. There are two ways to use: 1. when the switch is closed, the main power supply is powered on and soft boot works. 2. External switch to control. Soft boot works when switch is closed and stops when switch is disconnected.
Benefits:
Pumps, fans, cranes, soft boot of ordinary single-phase motor; replace the adjustable auto transformer, soft boot of inverter, etc.. Wiring is simple, and bypass contactor is not needed, economical and practical with powerful functions.
Note:
Model Selection Guide:
Aluminum substrate: SSR- 20WA-R(1KW), SSR- 40WA-R(1.5KW).
Copper substrate: SSR-60WA-R(2KW), SSR-100WA-R(4KW) SSR-150WA-R(6KW), SSR-200WA-R(8KW).
Notes while using:
When the starting potentiometer is set to half, it corresponds to the starting voltage of 110V,The maximum time of soft start potentiometer is 30 seconds, corresponding to the whole 220V.
