Product certification
The product meets the certification requirements of CE、TUV、EMC、RoHS、REACH、EEI≤0.23-part2
Note：RoHS2.0 and REACH are third-party test reports.
Startup time: the starting time of the circulating pump is less than 8S, that is, the time from power on to reach the maximum speed.
In PWM mode, when starting the circulating pump from the stop state (without power supply), 90% of the maximum speed must be reached in at most 8 seconds;
In PWM mode, start from standby mode to reach 90% of the maximum speed in at most 8seconds.
Shutdown time: the shutdown time of the circulating pump is less than 1s, that is, the time from power failure to shutdown of the circulating pump.
